Abstract
Objectives We assessed the safety and efficacy of balloon dilation as treatment for recurrent stenosis after pediatric laryngotracheoplasty. Methods We studied a retrospective case series at an academic tertiary care children's hospital. We included all patients under the age of 18 years with subglottic or tracheal stenosis treated at our institution with balloon dilation between June 2007 and April 2009. The records were analyzed for patient demographics, presenting symptoms, surgical technique, and airway description. The outcome measures were airway diameter, postoperative symptoms, tracheotomy status, and complications. Results Ten patients (9 with subglottic stenosis and 1 with tracheal stenosis) underwent 20 balloon dilation procedures without complication. The average age at the time of the procedure was 17 months (range, 3 months to 9 years). The patient presenting symptoms were stridor in 7 cases and tracheotomy in 3 cases. Vascular balloons (diameter range, 6 to 12 mm; length, 20 mm) were inflated to 10 to 12 cm H2O pressure for an average of 40 seconds (range, 10 to 120 seconds). Each procedure consisted of 1 to 3 dilation cycles. The immediate postdilation airway area increased by an average factor of 4.9 (range, 1.9 to 9). Six patients had repeat procedures with an average interval between dilations of 67 days (range, 6 to 337 days). Stridor was eliminated or greatly improved in all patients on the first postoperative day; 7 patients sustained this benefit, with an average follow-up time of 10 months (range, 4 to 23 months). Six of the 10 patients had undergone previous laryngeal reconstruction (age range, 3 months to 4 years). Of these 6, 3 have no tracheotomy, with a mean follow-up of 12.5 months. The 3 children who benefited the least from dilation were noted to have more diffuse and chronic inflammation of the larynx in comparison to the responders. Conclusions This case series suggests that balloon dilation is a relatively safe and effective procedure. It may be particularly well suited to recent stenosis after laryngotracheal reconstruction.

Abstract
Objectives: Balloon dilation for subglottic stenosis allows for a controlled radial expansion of the airway and is considered superior to older techniques of airway dilation. We report the case of a 39-year-old woman with idiopathic subglottic stenosis who had entrapment of an inflated balloon in her subglottis due to device failure while undergoing balloon dilation of the stenotic area. Methods: We present a case report and a review of the literature. Results: As a result of this and other reported incidents, on March 13, 2012, the US Food and Drug Administration issued a class 1 recall of the 18 × 40-mm Acclarent Inspira AIR Balloon Dilation System (Acclarent Inc, Menlo Park, California). Conclusions: This is the first report describing a dislodged inflated balloon in the subglottis as a complication of dilation for idiopathic subglottic stenosis. Awareness of this possibility, as well as preparedness with the proper instruments, is vital for prevention of a catastrophic emergency during an otherwise low-risk procedure.
