INTRODUCTION: Laryngomalacia is the most common congenital malformation of the larynx which causes stridor in newborns and infants. The stridor is inspiratory and it is first noted at birth but sometimes may not develop until 2 weeks of age. It increases in severity during crying, nursing, agitation, excitement and is made worse with head flexion or supination. Other symptoms such as supraclavicular, intraclavicular, intercostal and abdominal retractions may be associated. Boys are affected over twice as often as girls. Diagnosis of laryngomalacia is made by rigid or flexible laryngoscopy. Although this disorder is usually self-limited, in some cases the symptoms are so severe that operative intervention cannot be avoided. MATERIAL AND METHODS: Between 2002 and 2005, 13 infants were operated for severe form of laryngomalacia in the Pediatric ENT Dept in Poznań. In all patients the rigid or flexible laryngoscopy was performed to confirm the diagnosis. Then aryepiglottoplasty or epiglottoplasty were performed in all cases. It involved excision of the redundant mucosa over the arytenoid cartilages, the offending parts of he aryepiglottic folds, and trimming the lateral edges of the epiglottis, using microlaryngeal scissors and forceps. RESULTS: In all children symptoms such as: laryngeal stridor, feeding difficulties and dyspnea improved or completely resolved. In one case post-operative ventilation for several hours was required. All patients except one demonstrated significant airway improvement in the immediate postoperative period. CONCLUSIONS: Direct laryngoscopy must be performed prior to the aryepiglottoplasty to decide what amount of tissue to resect. Endoscopic aryepiglottoplasty with use of microlaryngeal instruments is an effective and safe method of the treatment of severe form of laryngomalacia. It is better to perform this procedure in general anesthesia without intubation.
