title: Anterior cricoid split for subglottic stenosis.
abstract: Subglottic stenosis is a common problem that often results from ventilatory support necessary in the premature infant. Previous methods of treatment include tracheostomy with dilatation of the stenosis, steroid injections, and procedures to stent the trachea. Results of these methods have been unsatisfactory because of the multiple procedures needed to obtain an adequate airway as well as the high mortality from long-term tracheostomy in infants. In the past 2 years, seven infants have undergone an anterior cricoid split for tight subglottic stenosis and airway obstruction. Of the seven patients, six were premature, five of whom required ventilatory support ranging from 4 to 30+ days. Each child presented in respiratory distress with symptoms present in five children from 1 to 11 months (mean 3.8) after birth. Bronchoscopy identified the site of obstruction in each case as subglottic, with a narrow lumen, usually less than 2.5 mm in diameter. Anterior cricoid split was performed at ages ranging from 2 to 11 months (mean 5.0). All children were extubated at 10 to 14 days and subsequently discharged home asymptomatic; none required postoperative tracheostomy. Complications developed in five children, including atelectasis, otitis media, phlebitis, and tracheocutaneous fistula in two, one of whom required operative closure. One child was rebronchoscoped at 3 weeks postoperatively for bronchospasm, which resolved on aminophylline. The subglottic trachea was normal. At follow-up ranging from 2 to 21 months (mean 8.3), no child has symptoms referrable to the subglottic region. In one patient, a brief period of respiratory distress recurred 3 months postoperatively due to tracheomalacia.(ABSTRACT TRUNCATED AT 250 WORDS)
