Laryngotracheoplasty to avoid tracheostomy in neonatal and infant subglottic stenosis.

ABSTRACT

OBJECTIVE: To outline the authors' experiences with performing laryngotracheoplasty as an alternative to tracheostomy in neonates and infants with symptomatic subglottic stenosis (SGS). STUDY DESIGN: Case series with chart review. SETTING: A tertiary referral pediatric hospital. SUBJECTS AND METHODS: Patients younger than 12 months undergoing single-stage laryngotracheoplasty for SGS at the authors' institution over a 3-year period. RESULTS: Ten patients (8 boys and 2 girls) underwent single-stage laryngotracheoplasty during the study period. There were 9 cases of acquired SGS and 1 case of congenital SGS. Eight patients had grade III SGS, and 2 patients had grade II SGS. In 9 of 10 patients, the procedure performed was an anterior cricoid split (ACS) and posterior cricoid split (PCS), with the placement of an anterior thyroid ala cartilage graft. One patient underwent ACS and PCS with the placement of a posterior rib cartilage graft, in combination with a right vocal cord lateralization. The mean period of intubation after surgery was 6.8 days (range, 5-9 days). Nine of 10 patients had a complete resolution of their airway symptoms following airway surgery, with a mean duration of follow-up of 305 days (range, 30-780 days). One patient required the placement of a tracheostomy tube 69 days postoperatively due to a failure to wean from ventilation in the setting of multiple comorbidities. CONCLUSION: Laryngotracheoplasty is a safe and effective alternative to long-term tracheostomy in infants and neonates with symptomatic SGS.
