Primary cricotracheal resection in children: indications, technique and outcome

Treatment of subglottic stenosis has benefited greatly from development of grafting techniques such as larygontracheoplasty. Meanwhile, cricotracheal resection of the stenotic area and a major part of the cricoid cartilage have been shown to give excellent results in adults.

From June 1993 to June 2000, we performed cricotracheal resection, as the primary surgical procedure, for acquired (n=13), congenital (n=2) or mixed (n=l) subglottic stenosis in 16 pediatric patients comprising seven boys and nine girls. At the time of surgery, the mean weight was 16 kg and the mean age was 5 years. Degree of stenosis was classified as grade II in one case, grade III in 12, and grade IV in three. Eight patients underwent two-stage procedures with postoperative tracheostomy. A rolled reinforced silastic stent was placed for a mean period of 20 days and the tracheostomy tube was removed within a mean period of 44 days after stent removal. Eight patients underwent single-stage procedures. The Portex endotracheal tube was used for a mean period of 4 days.

All patients underwent regular clinical and endoscopic postoperative examination. Mean follow-up was 38 months. No interference with laryngotracheal growth has been noted in any case, including the five with follow-ups longer than 5 years.

The indications for laryngotracheoplasty and cricotracheal resection in children with subglottic stenosis are still unclear. Decisions must be made on a case-by-case basis. In this article the authors discuss decisional factors in terms of clinical findings, surgical techniques, potential complications, and outcome.
