Abstract
Between 1987 and 1993, 115 children were operated on for severe forms of laryngomalacia in two pediatric ear, nose, and throat (ENT) departments. The criteria used to determine the severity of the illness were selected following short hospitalization periods during which the children received both pediatric and ENT checkups. Based on clinical manifestations and/or the results of pH monitoring gastroesophageal reflux was found to be present in 68% of the children in the study. Detailed analysis and endoscopy were used to differentiate the symptoms that were related to laryngomalacia from those that were caused by other conditions, including mixed‐breathing, swallowing, and sucking difficulties.Endoscopic resection of the aryepiglottic folds, with or without the use of a carbon dioxide laser, resulted in rapid improvement of both ventilation and swallowing. The success rate of this simple and effective procedure, which has no inherent morbidity, was 98% in an average follow‐up period of 30 months. Only seven children required an additional similar procedure. The procedure failed in only two children, who needed to be tracheotomized. Given these excellent results, endoscopic resection can be considered an effective technique for the management of severe laryngomalacia.
