Endoscopic division of the ary-epiglottic folds in severe laryngomalacia.
OBJECTIVE
Laryngomalacia is the commonest cause of congenital stridor. The underlying anatomical abnormality associated with this condition is a prolapse of the supraglottic tissues into the laryngeal inlet during inspiration, and may involve the epiglottis, ary-epiglottic folds and the corniculate mounds of the arytenoids. However, it has been noted that the most consistent structural abnormality seen in these cases is the shortening of the ary-epiglottic folds and marked side to side curling of the epiglottis. We describe the follow-up and outcome of 33 cases treated by the simple division of the ary-epiglottic folds.


METHODS
All case notes were reviewed with respect to indications of operation, age of operation, endoscopic findings, operative technique, complications and follow-up until resolution of symptoms.


RESULTS
Surgical outcomes could only be ascertained in only 32 patients. Twenty-two cases (68.7%) showed complete resolution of stridor and associated complications of laryngomalacia. In the remaining ten cases who could be followed up (31.2%), seven patients (21.8%) showed partial resolution with no further surgery required, two patients (6.2%) required additional excision of redundant mucosa as second procedure, one patient (3%) with associated cleft lip/palate and tracheomalacia had to undergo a tracheostomy. There was improvement in feeding after surgery in all the 12 patients (100%) who had had pre-operative feeding difficulties. All the four patients with cyanosis pre-operatively were cured, but one of the two patients with apnoeic episodes pre-operatively continued to have apnoeic spells despite resolution of their laryngomalacia.


CONCLUSIONS
Simple endoscopic excision of the ary-epiglottic folds is a quick, reliable, highly effective procedure with very few complications. We recommend its use as the first line option in the management of severe laryngomalacia, with more extensive methods reserved for the very occasional case of primary failure.
