Management of supraglottic dysgenesis presenting as laryngomalacia.

چکیده
Laryngomalacia is a common source of stridor and can lead to significant upper airway obstruction and feeding disturbances in infants. We describe a unique case of supraglottic dysgenesis presenting as laryngomalacia featuring a prominent "s-shaped" epiglottis with both posterior edges fused to the right aryepiglottic fold/arytenoid complex. Although this anomaly is not accounted for in any of the current laryngomalacia classification schemes, modified laser supraglottoplasty was a satisfactory approach leading to successful decannulation. Laryngeal embryology and possible timing of the pathogenesis of this rare occurrence are reviewed as well.

Laryngomalacia and Tracheomalacia — Diagnosis and Treatment
Laryngomalacia is a congenital condition that is characterized by the abnormal development of supraglottic structures, such as the epiglottis. The supraglottic structures tend to collapse during inspiration, causing stridor and, in severe cases, hypoxemia. Tracheomalacia is a more serious condition of abnormally developing tracheal cartilage that is characterized by tracheal lumen collapse dura...

Respiratory symptoms on exertion, such as shortness of breath and wheezing, are commonly associated with asthma, but might also arise from the larynx [1–3]. In recent years, the emergence of exercise laryngoscopy [4] has led to a better understanding of laryngeal movement during exercise, and inspiratory supraglottic collapse on exertion has been established as a common cause of exertional brea...

متن کاملAcquired idiopathic laryngomalacia treated by laser supraglottic laryngoplasty.
Laryngomalacia is the most common cause of stridor in neonates and infants, where the soft cartilages and tissues surrounding the upper larynx collapse inward during respiration. On the other hand, acquired idiopathic laryngomalacia in adults is quite rare, but should be borne in mind for differential diagnosis of upper airway distress. Allergic factors may cause airway distress, but have not b...
