Risk Factors for Supraglottoplasty Failure

Objective. To review outcomes after supraglottoplasty for laryngomalacia and identify risk factors for supraglottoplasty failure. Study Design. Case series with chart review. Setting. Tertiary care children’s hospital. Subjects and Methods. Retrospective case series evaluating patient outcomes after supraglottoplasty at an academic medical center between 2004 and 2010. Surgical failure was defined as need for revision surgery, tracheostomy tube placement, or gastrostomy tube insertion. Multivariable logistic regression was performed to identify risk factors for failure. Results. The authors identified 95 children who underwent supraglottoplasty. After excluding patients with inadequate follow-up data, 74 patients were included. On the basis of chart review, 12 (16%) of those patients were defined as failures according to the criteria above. Age, history of prematurity (
