Fifty-eight infants and children with a severe subglottic stenosis underwent a partial cricotracheal resection with primary thyrotracheal anastomosis. There were 2 grade II, 40 grade III, and 16 grade IV stenoses according to the Myer-Cotton classification. A 100% subglottic lumen was formed in 34 cases and a better than 80% lumen in 23 cases. Fifty-four of the 58 (93%) patients are presently decannulated; one patient sustained a complete restenosis and three patients with a better than 80% subglottic airway still await decannulation for the following reasons: severe tracheomalacia, bilateral cricoarytenoïd joint fixation and laryngeal malformation with fusion of the vocal cords in each case respectively. Forty-four patients have no exercise intolerance, 8 live fully normally but present a slight exertional dyspnea, one patient with a laryngeal malformation is decannulated but suffers from a severe exertional dyspnea, and 4 patients are still not decannulated. The voice is normal in 20 cases, a slight dysphonia is present in 17, a moderate to severe dysphonia in another 17 and 4 patients are still not decannulated.
