Cricotracheal resection for pediatric subglottic stenosis.
Until recently, cricotracheal resection (CTR) has not been commonly accepted as a treatment modality for severe subglottic stenosis in the pediatric age group. The reasons have included the risk of a possible dehiscence at the site of the anastomosis, the likelihood of injury to the recurrent laryngeal nerves, and the interference with normal growth of the larynx. Thirty-eight infants and children with a severe subglottic stenosis underwent a partial cricoid resection with primary thyrotracheal anastomosis. Thirty-three patients were tracheotomy-dependent at the time of surgery and 34 were referred cases; 27 were classified as grade III, and 10 as grade IV stenoses according to new Cotton's classification. Nineteen patients were younger than 3 years of age at the time of surgery. The tracheotomy was resected during the surgical procedure in 21 cases. Decannulation was achieved in 36/38 cases after an open procedure. There is one complete restenosis and one good result awaiting decannulation after further surgery for a Pierre Robin syndrome. The authors experienced no lesion of the recurrent laryngeal nerves and no fatality. Thirty-one patients show no exertional dyspnea, three a slight stridor while exercising, and two patients are not decannulated. The postoperative follow-up in longer than 10 years in eight cases. All patients show a normal growth of the larynx and trachea. Compared to laryngotracheoplasties, CTR gives better results for severe subglottic stenosis. This operation should become the treatment of choice for severe (grade III and IV) subglottic stenosis in infants and children.
