There may be multiple tiny pits or a vestige of the tympanic portion of the temporal bone (cribriform area) that are landmarks used to begin drilling. Drilling continues medially until the thin bony atretic plate and opening into the attic are identified. Recently, acceptable hearing results with canal wall-down atresiaplasties have been reported (discussed later). A majority of surgeons favor the anterior (lateral) approach as described by Jahrsdoerfer. A postauricular incision is made, and the reconstructed auricle is elevated in the plane of the temporalis fascia. Care is taken to leave perichondrium on the auricular graft and to preserve its anterior blood supply. Drilling begins as described in the Key Anatomic Landmarks section provided previously. An angled telescope is used to identify ossicles through an opening in the atretic plate. Diamond burs are used to thin the atretic plate to eggshell thickness, and then it is gently removed with picks and curets. When mobilizing a fixed ossicle, it is important to remove significant bone near the fixation site, lest new bone and fibrosis cause recurrent fixation. If stapes surgery is required, it is preferable as a second stage procedure after complete healing. Jahrsdoerfer recommended placing a small disc of thick Silastic over 208 Prerequisite Skills Extensive experience with tympanoplasty, mastoidectomy, ossicular reconstruction, stapedectomy, atresiaplasty, and some knowledge of microtia reconstruction is required. Avoid drill trauma to ossicles during separation from and removal of the atretic plate. A large external auditory meatus is created by excising a disc of tissue from the reconstructed auricle after a pedicled skin flap has been preserved. The skin graft is brought out through the external auditory meatus and sutured to the skin and flap from the meatus. Combined Microtia and Atresiaplasty Surgeons have combined microtia reconstruction with atresiaplasty. External auditory canal lined with split-thickness skin graft and Silastic disc over temporalis fascia graft. Externally, the incision is extended superiorly just anterior to the root of the helix. Anterior and posterior canal incisions are made from this point to create two triangular flaps that are back-elevated. If exposed bone is extensive/circumferential, then a split-thickness skin graft is required since full-thickness skin is too bulky. A postauricular approach is performed for wide exposure and the auricle is elevated forward. Complications Complications of Atresiaplasty Following atresiaplasty, stenosis is the most common complication (0% to 25%) and most common indication for revision surgery. Triamcinolone injection into the meatus at surgery or subsequently may prevent or improve stenosis. Wicks, stents, and molds decrease or prevent stenosis and may be required for 6 months. In a systematic review, the average hearing gain for atresiaplasty was 24 dB (516 ears), while the average gain for percutaneous osseointegrated implants was 38 dB (100 ears). However, the best possible outcome is an uncomplicated continuous excellent cosmetic and hearing result from atresiaplasty with no requirement for electronic devices. A higher incidence of injury was associated with a lower Jahrsdoerfer grading score, indicating less favorable anatomy. It likely occurs from transmission of drill energy to ossicles during removal of the atretic plate. Effects of aural atresia on speech development and learning: retrospective analysis from a multidisciplinary craniofacial clinic. Hearing outcomes of atresia surgery versus osseointegrated bone conduction device in patients with congenital aural atresia. In the Jahrsdoerfer grading system, the anatomic structure awarded two points is a. Disadvantages of percutaneous osseointegrated implants include all of the following except a. Children with auricular deformities, particularly prominent ears, may be the subject of teasing by peers, which can affect psychosocial development, self-esteem, and school performance. In part, this may be due to how prominent ears draw the eye of the viewer away from the central face and eyes of the subject and toward the auricular deformity. In addition, in popular culture and political cartoons, prominent ears are often used to depict an individual with decreased intelligence. Otoplasty represents a relatively simple surgical solution with potentially very gratifying results. One challenge for the novice surgeon is that more than 200 techniques have been described in the literature. The goal of corrective surgery is to restore the normal contours and dimensions of the auricle, symmetry, and degree of protrusion from the scalp. Proper analysis of the deformity preoperatively is essential to developing an appropriate surgical plan to optimize results and patient satisfaction. Family history: Is there a family history of bleeding disorders, connective tissue disorders, or auricular deformities Ask about medication exposures that may affect bleeding or wound healing, such as: 1) Antiplatelet drugs 2) Herbal products 3) Smoking or smoke exposure Physical Examination 1. Examination of the auricle: Careful examination and documentation of the auricular anatomy is crucial, including measurement of the auricular dimensions, projection, and degree of development of the conchal bowl and antihelix. Examination of the preauricular area may reveal accessory tragi or sinus tracks that may be addressed concurrently. Gentle pressure on the posterior-superior aspect of the helical rim may be used to recreate an antihelical fold and is useful in assessing preoperatively if this is sufficient to correct the deformity. Otoscopic examination Examination of the ears with an otoscope may rule out external auditory canal stenosis or atresia. Facial symmetry Especially in unilateral cases of auricular deformity, the presence of facial asymmetry, hemipalatal paresis, or jaw discrepancy may indicate a need for further assessment for hemifacial microsomia. Most auricular deformities will have been present from birth, but it is important to elicit any changes in ear development or auricular trauma by asking: What did the ear(s) look like at birth Occasionally a child may present for consideration of otoplasty and may actually have grade I microtia or even aural atresia or external auditory canal stenosis. Photo documentation is helpful for preoperative planning; potentially for insurance authorization and for medicolegal purposes. Prominent ear deformity with desire to correct auricular proportions or projection 2. Significant, uncorrected bleeding disorder or nutritional deficiency that would increase risk for complication with wound healing 3. Typical postoperative view of the auricle after addressing the underdeveloped antihelix and deep conchal bowl, with intentional overcorrection of antihelix. Patients should be counseled on postoperative care and advised on realistic surgical outcomes, including that mild asymmetry of auricular shape and protrusion is natural and absolutely perfect symmetry is unrealistic. The pocket should be just wide enough to place the smallest rasp to score the cartilage. Alternatively, the beveled edge of an Adson-Brown tissue forceps may be used for cartilage scoring. Care should be made to ensure that all fragments of cartilage are suctioned or expressed out of the pocket. Fullthickness horizontal mattress sutures using 4-0 undyed nylon suture, or similar, from the postauricular approach to recreate the antihelical fold. These should be tightened up to and just past the point of creating a natural antihelical fold. Address an excessively deep conchal bowl by excising a small fusiform strip of cartilage from the concha cavum, taking care to avoid injury to the crus of the helix and leaving the perichondrium and the skin of the external auditory canal intact. If needed, conchomastoid sutures may be placed in a radial fashion to prevent external auditory canal meatal stenosis. If this suture is placed too far posteriorly, the suture itself may be palpable or even visible and create tenting of the postauricular skin. Placing the sutures in a radial fashion is useful in preventing external auditory canal meatal stenosis. Close the deep layer of the incision with 4-0 Vicryl in an interrupted, buried fashion and the superficial layer with 5-0 plain or fast-absorbing suture, or similar. If the lobule seems to be overly protruding, a small M-plasty may be fashioned at the inferior aspect of the incision to address the lobule protrusion. Apply antibiotic ointment and nonadherent dressing to the incision, fluffs, and a lightly compressive dressing. Overcorrection of lobule and superior aspect of auricle -reverse telephone deformity 5. A less conspicuous head-wrap or headband may be worn thereafter for 2 to 3 weeks to maintain ear position during initial healing. Pain medication: Patients should be expected to have mild pain after this operation. Pain beyond expectation in the early postoperative period may indicate a hematoma or early infection. If using a replaceable head-wrap, such as a Glascock dressing, topical antibiotic ointment may be use on the incision for 3 days followed by Aquaphor ointment, thereafter. Seroma or hematoma-may require needle aspiration or opening of incision for drainage 2. Wound infection and/or breakdown-Any purulence should be cultured and appropriate antibiotic management prescribed. A portion of the wound may need to be opened to allow for drainage and healing by secondary intention. External auditory canal meatal stenosis-Again, prevention is key by checking external auditory canal patency at the conclusion of the procedure and by placing conchomastoid sutures in a radial fashion. Intraoperatively, if there is concern for stenosis, despite these measures, a canal stent may be placed for 1 week and removed at the first postoperative visit. Editorial Comment Otoplasty may be challenging techniquely for the surgeon but gratifying for the patient. Knowledge of the normal anatomic contours of the ear is crucial for the success of otoplasty. Like many facial plastic surgery procedures, a variety of described methods exist to accomplish the same goal. The most significant variations are for marking the antihelix, for cartilage contouring, and for cartilage excision. In my practice, I mark the desired suture locations for the antihelix with needles placed on the anterior aspect of the pinna. Additionally, I tend to avoid any cartilage scoring or cartilage excision, if possible. Over the years, I have begun to slightly overcorrect the auricular deformity with the expectation that, over time, the ears tend to lateralize. Patients should be pre-operatively counseled that the range of normal is quite broad with regard to the size, shape, and projection of the pinna. The method described above provides a sound approach to achieving the desired patient outcomes and creating a natural, reproducible appearance and symmetry between the ears. There is little evidence to support or to oppose the use of antibiotic prophylaxis routinely for otoplasty. Of the 20 studies between 2000 and 2007 that met the inclusion criteria for review, only one mentioned a wound infection, with a rate of 3. Of the studies without a reported wound infection, only four explicitly described use of prophylactic antibiotics. In 2004 a Cochrane review demonstrated that there is no strong evidence to support antibiotic prophylaxis in clean and clean-contaminated ear surgery. However, there is likely an underreporting bias in the literature, such that most complications in otoplasty are not reported. Thus, although evidence is limited to support its use, I do use cephalexin by mouth for 7 days following the procedure, in addition to bacitracin ointment on the incision for 3 days.

Cranial irradiation may cause vascular endothelial damage and induce development of multiple cavernous or telangiectatic-like lesions in the brain parenchyma 5 medications for hypertension buy paxil 40 mg with visa. No specific correlation has been observed between genotype and phenotype of brain vascular malformation medicine 3604 pill discount paxil 10 mg free shipping. These can be seen as areas of poorly delineated pink or brownish discoloration in the parenchyma (7-53) symptoms internal bleeding order 20 mg paxil free shipping. A cluster of dilated medicine 8 - love shadow paxil 10 mg discount, somewhat ectatic but otherwise normal-appearing capillaries interspersed within the brain parenchyma is characteristic (7-55) treatment jones fracture cheap paxil 40 mg with visa. Capillary telangiectasias are the second most common cerebral vascular malformation k-9 medications buy cheapest paxil and paxil, representing between 10-20% of all brain vascular malformations. Skin and mucosal capillary telangiectasias are even more common than brain telangiectasias. As blood flow within the dilated capillaries is quite sluggish, oxyhemoglobin is converted to deoxyhemoglobin and is visible as an area of poorly delineated grayish hypointensity. Larger lesions may demonstrate a linear focus of strong enhancement within the lesion, representing a draining collector vein (7-57C). Most are cavernous malformations with microhemorrhages, not capillary telangiectasias. Stroke syndromes have significant clinical and pathophysiological heterogeneity that is reflected in their underlying gross pathologic and imaging appearances. Arterial ischemia/infarction-the major focus of this chapter-is by far the most common cause of stroke, accounting for 80% of all cases. With this solid anatomic foundation, we then turn our attention to the etiology, pathology, and imaging manifestations of arterial strokes. In order, these are (1) a short posterior ascending (vertical) segment, (2) the posterior genu, (3) a longer horizontal segment, (4) an anterior genu, and (5) an anterior vertical ascending (subclinoid) segment. Therefore, on anteroposterior or coronal views, the posterior genu is lateral to the anterior genu. The meningohypophyseal trunk arises from the posterior genu, supplying the pituitary gland, tentorium, and clival dura. The C2 (petrous) segment is contained within the carotid canal of the temporal bone and is L-shaped (8-1). Biopsy may result in stroke or fatal hemorrhage, so this anomaly must be recognized by the radiologist and communicated to the referring clinician. Coronal images show a round, well-delineated soft tissue density lying on the cochlear promontory (8-4B). A distinct angulation that resembles a 7 is often present, together with a change in contour and caliber (pinched appearance) before the segment resumes its normal course (8-4C). Early in embryonic development, connections form between the primitive carotid artery and the two longitudinal neural arteries (the fetal precursors of the basilar artery). Each is recognized and named according to its anatomic relationship with specific cranial or spinal nerves. This variant is important to recognize prior to transsphenoidal surgery for pituitary adenoma. The primitive otic artery is the first of the fetal carotid-basilar anastomoses to regress and is therefore the rarest of these uncommon anomalies. The A2 segment has two cortical branches, the orbitofrontal and frontopolar arteries, that supply the undersurface and inferomedial aspect of the frontal lobe. The pericallosal artery is the larger of the two terminal branches, running posteriorly between the dorsal surface of the corpus callosum and cingulate gyrus. The medial lenticulostriate arteries pass superiorly through the anterior perforated substance to supply the medial basal ganglia. Arterial Anatomy and Strokes callosomarginal artery courses over the cingulate gyrus within the cingulate sulcus (8-12). An infraoptic A1 occurs when the horizontal segment passes below (not above) the optic nerve. Thalamogeniculate arteries and peduncular perforating arteries arise from the proximal P2 and pass directly superiorly into the midbrain (8-21). The most important branches that arise from the M1 segment are the lateral lenticulostriate group of arteries and the anterior temporal artery. The lateral lenticulostriate arteries supply the lateral putamen, caudate nucleus, and external capsule (8-17). The medial trunk gives off the medial occipital artery, parietooccipital artery, calcarine artery, and posterior splenial arteries, whereas the lateral trunk gives rise to the lateral occipital artery. It also supplies the occipital lobe, posterior onethird of the medial hemisphere and corpus callosum, and most of the choroid plexus (8-23). P4 segments (cortical branches) ramify over the occipital and inferior temporal lobes. Arterial Anatomy and Strokes is present on one side, this can produce substantial left-right asymmetry on perfusion imaging. Knowledge of this common normal variant is essential, as such asymmetry can mimic cerebrovascular pathology. Here a single dominant thalamoperforating artery arises from the P1 segment and supplies the rostral midbrain and bilateral medial thalami (8-88). Unnamed segmental branches arise from V1 to supply the cervical musculature and lower cervical spinal cord. The V2 segment courses superiorly through the C6-C3 transverse foramina until it reaches C2, where it first turns superolaterally through the "inverted L" of the transverse foramen and then turns upward to pass through the C1 transverse foramen (8-24). An anterior meningeal artery and additional unnamed segmental branches arise from V2. It lies on top of the C1 ring, curving posteromedially around the atlantooccipital joint before making a sharp anterosuperior turn to pierce the dura at the foramen magnum. It gives off small anterior and posterior spinal arteries and medullary perforating branches. It terminates in the interpeduncular fossa by dividing into the two posterior cerebral arteries. It supplies both nerves as well as a relatively thin strip of the cerebellar hemisphere that lies directly behind the petrous temporal bone. Arterial Infarcts We first focus on the pathology and imaging of major arterial ischemia-infarction, starting with acute lesions. Subacute and chronic infarcts are then discussed, followed by a brief consideration of lacunar infarcts. Acute Cerebral Ischemia-Infarction As the clinical diagnosis of acute "stroke" is inaccurate in 1520% of cases, imaging has become the basis of rapid stroke triage. When and how to image patients with suspected acute stroke varies somewhat from institution to institution. Acute stroke protocols are based on elapsed time since symptom onset, availability of emergent imaging with appropriate software reconstructions, clinician and radiologist preferences, and availability of neurointervention. Because imaging has become so critical to patient management, we will focus in detail on hyperacute/acute stroke imaging. There are four "must know" questions in acute stroke triage that need to be answered rapidly and accurately. Vascular Territory the vertebrobasilar system normally supplies all of the posterior fossa structures as well as the midbrain, posterior thalami, occipital lobes, most of the inferior and posterolateral surfaces of the temporal lobe, and upper cervical spinal cord (8-27). In cerebral ischemia, the affected tissue remains viable although blood flow is inadequate to sustain normal cellular function. In cerebral infarction, frank cell death occurs with loss of neurons, glia, or both. Hyperacute stroke designates events within the first 6 hours following symptom onset. In hyperacute stroke, cell death has not yet occurred, so the combined term acute cerebral ischemia-infarction is often used. Arterial Anatomy and Strokes Etiology Ischemic stroke is a heterogeneous disease with different etiologies and several subtypes. Etiology varies with stroke subtype, and stroke subtypes also vary by racial and ethnic groups. Intracranial atherosclerosis causes 30-50% of strokes in Asians but only 8-10% in North America. Genome-wide analysis has also identified a strong overlap between large artery stroke and migraine headaches, especially those without aura. Small artery occlusions, also called lacunar infarcts, are defined as lesions measuring less than 15 mm in diameter. Most involve penetrating arteries in the basal ganglia/thalami, internal capsule, pons, and deep cerebral white matter. Common risk factors include myocardial infarction, arrhythmia (most often atrial fibrillation), and valvular heart disease. Other is a heterogeneous group that combines strokes with miscellaneous but known etiologies together with strokes of undetermined etiology ("cryptogenic stroke"). Oxygen is rapidly depleted, cellular energy production fails, and ion homeostasis is lost. Neuronal death with irreversible loss of function occurs in the core of an acute stroke. A relatively less ischemic penumbra surrounding the central core is present in about half of all patients. This ischemic but not-yet-doomed-to-infarct tissue represents physiologically "at risk" but potentially salvageable tissue. There is a well-defined histologic "hierarchy of sensitivity" to ischemic damage among the different cell types that constitute the neuropil. They are followed (in descending order of susceptibility) by astrocytes, oligodendroglia, microglia, and endothelial cells. There is also a geographic "hierarchy of sensitivity" to ischemic damage among the neurons themselves. Hypertension, diabetes, smoking, metabolic syndrome, and elevated triglycerides are significant known predisposing factors. Acute infarcts can be solitary or multiple and vary in size from tiny lacunar to large territorial lesions that can involve much of the cerebral hemisphere. An acutely thrombosed artery is filled with soft purplish clot that may involve the entire vessel or just a short segment (8-29A). Clot extension into secondary branches with or without distal emboli into smaller, more peripheral vessels is common. Longer and larger thrombi are also associated with reduced probability of reperfusion after intravenous thrombolysis, so thrombectomy may be necessary to maximize the probability and speed of recanalization. Gross parenchymal changes are minimal or absent in the first 6-8 hours, after which edema in the affected vascular territory causes the brain to appear pale and swollen. Frank cerebral infarction is characterized by irreversible damage to all cells within the infarcted zone. Within 12-24 hours, acutely ischemic neurons classically appear "red and dead" with hypereosinophilic cytoplasm, early karyolysis, and pyknotic nuclei. Acute infarcts are pale and often vacuolized, especially near the junction with intact brain. Stroke is the third leading cause of death in many industrialized countries and is the major worldwide cause of adult neurologic disability. Strokes affect patients of all ages-including newborns and neonates-although most occur in middle-aged or older adults. Children with strokes often have an underlying disorder such as right-to-left cardiac shunt, sickle cell disease, or inherited hypercoagulable syndrome. Strokes in young adults are often caused by dissection (spontaneous or traumatic) or drug abuse. Stroke symptoms vary widely, depending on the vascular territory affected as well as the presence and adequacy of collateral flow. Sudden onset of a focal neurologic deficit such as facial droop, slurred speech, paresis, or decreased consciousness is the most common presentation. Between 20-25% of strokes are considered "major" occlusions and cause 80% of adverse outcomes. Six months after stroke, 20-30% of all patients are dead, and a similar number are severely disabled. Nearly half of all strokes have inadequate collateral blood flow and no significant penumbra. Most patients with major vessel occlusions-even those with a significant ischemic penumbra-will do poorly unless blood flow can be restored and the brain reperfused. Stroke treatment options and inclusion/exclusion criteria are continually evolving. Acute ischemia is seen as subtle loss of gray-white interfaces and "blurred" basal ganglia. Exceptions to this general rule include basilar artery thrombosis and patients outside the 6-hour window who have a persistent significant perfusion-diffusion mismatch. Endovascular thrombectomy benefits most patients with acute ischemic stroke caused by occlusion of the proximal anterior circulation and offers an alternative, potentially synergistic method to thrombolysis. Its advantages include delivering site-specific therapy and tailored thrombolytic dosage. Mechanical thrombectomy may also be suitable in patients beyond the therapeutic window or in whom thrombolytic therapy is contraindicated. The primary goals of emergent stroke imaging are (1) to distinguish "bland" or ischemic stroke from intracranial hemorrhage and (2) to select/triage patients for possible reperfusion therapies. Once intracranial hemorrhage is excluded, the second critical issue is determining whether a major cerebral vessel is occluded. Nontraumatic Hemorrhage and Vascular Lesions 212 choice for depicting potentially treatable major vessel occlusions.

This sound was subsequently termed stridor in 1853 by Rilliet and Barthez in their textbook, Of Diseases of Children. It was not until 1897 that the laryngoscopic physical findings associated with this disorder were accurately described in 16 patients by Sutherland and Lack as congenital laryngeal obstruction, while the actual term "laryngomalacia" ("malacia," Greek malakia-softening of part of tissue) was not used until 1942 when Chevalier Jackson described this disorder. The predominant underlying concepts to explain this supraglottic instability are excess redundant mucosa, poor cartilaginous support, and/or abnormal neurologic laryngeal tone. Laryngomalacia affects approximately 35% to 75% of infants presenting with stridor and is the most common cause of stridor in the pediatric age group. Respiratory symptoms are often exacerbated with feeding, exertion, and supine positioning. Swallowing dysfunctions (penetration or aspiration) have been reported in up to 88% of patients with severe laryngomalacia. First described in 1922 by Iglauer, supraglottoplasty is a generalized term used to describe a surgical technique in which the supraglottic structures of the larynx are altered in a manner to prevent further collapse and subsequent obstruction of the glottic introitus. This technique did not replace the tracheostomy for relief of laryngomalacia until the 1980s when refined and modernized by Drs. Supraglottoplasty has a reported success rate of over 90% in otherwise healthy children with this disease. This procedure is performed transorally using suspension laryngoscopy and microlaryngeal instruments. It has a high success and a low morbidity rate, making it a first-line option for the otolaryngologist. Laryngomalacia is predominately self-limiting, with resolution typically by 18 months of age. Children with laryngomalacia can present with various aerodigestive complaints that can affect overall child health as well as child and parental quality of life. Supraglottoplasty is a surgical technique reserved for severe laryngomalacia and is a safe procedure. Supraglottoplasty is the surgical treatment of choice when conservative therapy fails. Congenital anomalies and syndromes 1) Estimated in 8% to 20% of patients with laryngomalacia and up to 40% in patients diagnosed with severe laryngomalacia3,8 2) Down syndrome is the most common associated genetic disorder. Antiplatelet medications and herbal supplementation associated with increased bleeding should be discontinued prior to surgical intervention. Piriform aperture stenosis, choanal stenosis, and choanal atresia should be ruled out by nasal endoscopy or at the minimum cannulation with a 6- or 8-French nasogastric tube. A stethoscope can be placed over the neck, specifically over the supraglottis, glottis, subglottis, and over the thorax to localize stridor and/or wheezing. Allows for examination of supraglottic structures on inspiration and associated pathology contributing to laryngomalacia c. Direct laryngoscopy and bronchoscopy with possible supraglottoplasty should be performed on all of the following:7 a. Infants with laryngomalacia and severe respiratory distress, failure to thrive, apnea events, or recurrent pneumonia b. Medical comorbidities with increased risk of anesthesia and inability to tolerate spontaneous ventilation 2. Patients currently intubated or tracheostomy tube dependent secondary to ventilator dependence. Respiratory and swallowing status should be stabilized to the best scenario prior to surgery (supplemental oxygen, hospital admission, thickening of feeds, and nasogastric tube feeding). Complications and indications of the procedure should be discussed at length with responsible individuals. Polysomnogram-optional Patients with laryngomalacia often demonstrate associated sleep apnea and hypopnea. Incision of the right aryepiglottic fold using microlaryngeal scissors and a microlaryngeal cup-forcep. To avoid this, a long laryngeal suction and an appropriate-sized endotracheal tube should be available. Bulb syringe with normal saline should be readily available for copious irrigation. Intravenous dexamethasone can be utilized prior, during, and post surgery to decrease swelling. Using a laryngoscope in the left hand, the oral cavity is entered from the right side medial to the oral commissure. The tongue is then swept to the left, and the laryngoscope is inserted into the vallecula. Using an anterior superior motion, the tongue is brought out of view, the epiglottis is moved to the anterior superior position, and all supraglottic structures are now in view. Once in proper/desired view of the supraglottic anatomy, the laryngoscope holder is then connected, and the stabilizing arm is lowered onto the Mayo stand to secure the suspended view. Using cup or grasping forceps, apply adrenaline-saturated pledgets to area of planned incision. Using cup or grasping forceps, apply adrenaline-saturated pledgets to area of planned excision. The laryngoscope is positioned to ensure proper view of the lingual surface of the epiglottis and the base of the tongue. Optional: On postoperative day 1, a bedside swallowing evaluation by a speech pathologist can be performed to evaluate safety of oral intake. Postoperative edema and associated airway obstruction Dysphagia Aspiration or penetration Residual laryngomalacia Supraglottic stenosis Alternative Management Plan 1. Observation is the most appropriate form of management for the majority of non life-threatening cases of laryngomalacia, as most symptoms will resolve by 18 months of age. During this time, associated factors such as reflux can be managed conservatively. Historically, tracheotomy was the standard therapy for severe laryngomalacia, though this is now only used in as an absolute last resort after failed supraglottoplasty attempts and is primarily performed on children with other comorbidities. Excision of redundant right arytenoid tissue using curved microlaryngeal scissors and a microlaryngeal cup forcep. Sutures are placed through the superior aspect of the denuded lingual surface of the epiglottis and then through the base of the tongue. Anatomically, the augmented labored respiratory pattern and increased intrathoracic pressure generated in these patients may encourage extraesophageal reflux. When is supraglottoplasty indicated, and how successful is supraglottoplasty in the treatment of laryngomalacia Does supraglottoplasty increase the risk of aspiration or penetration postoperatively Without proper release and incision down to directly above the false vocal folds, incomplete results can occur. Supraglottic stenosis can occur as a result of overly aggressive excision of supraglottic tissue. This occurs when excision of redundant arytenoid mucosa is performed in a medial direction toward the glottis introitus and/or toward the interarytenoid region. Aspiration or penetration can result from overly aggressive surgery in which the supraglottic mucosa has decreased sensation or too much tissue and associated protective elements are removed. Care must always be taken to release the suspension element and ensure that excessive and prolonged pressure are not placed on delicate tissue. Laryngomalacia 1361 Editorial Comment Laryngomalacia is the most common cause of pediatric stridor and is a disease that is encountered by all clinicians involved in the care of children. Though primarily selflimiting, the surgical indications for supraglottoplasty have increased over the past decade as more has been learned about this disease and its global effect on the upper aerodigestive system. Supraglottoplasty is a relatively safe procedure and can improve or resolve all the above ailments when properly performed on indicated children.
