Experience with anterior cricoid split for infantile subglottic stenosis

A retrospective study of infants undergoing anterior cricoid split (ACS) from 1989 to 1993 was performed to evaluate our unit's experience with ACS in the management of infantile subglottic stenosis (SGS). Twelve children were identified ranging in age from 10 to 30 weeks and weighing between 1200 and 6500 g. Nine were born at or less than 30 weeks' gestation. Indications for surgery were endotracheal tube dependency, nasopharyngeal continuous positive airway pressure dependency and recurrent croup. All had varying degrees of SGS. Eleven of the 12 patients were extubated successfully following surgery. Two of these required subsequent repeat ACS 6 and 9 months later with one patient eventually requiring tracheostomy. These results suggest that ACS can be safely employed as an alternative to tracheostomy for a variety of clinical presentations of infantile SGS, with a relatively high rate of successful extubation.
