title: Microdebrider removal under suspension laryngoscopy: an alternative surgical technique for subglottic hemangioma.
abstract: OBJECTIVE
  To describe microdebrider removal of subglottic hemangiomas and evaluate the efficacy of this procedure.
  
  
  METHODS
  This retrospective study was conducted at an otorhinolaryngology department. Seven consecutive patients with subglottic hemangiomas who failed to respond to pharmacologic treatment were treated by microdebrider removal under suspension laryngoscopy. Respiratory symptoms and hemangioma status were assessed preoperatively and postoperatively.
  
  
  RESULTS
  The mean age of patients at disease onset was 68 days (range, 24-120 days), and their mean age at the time of surgical treatment was 132 days (range, 55-195 days). Their initial pharmacologic treatment included steroids, propranolol, and/or antibiotics. The mean percentage of airway obstruction was initially 36% (range, 30-50%), and this value changed to 61% (50-80) before surgery. Microdebrider removal of hemangiomas was successful in all patients without any intraoperative or postoperative complication. The mean operative time was 30 min (range, 21-47 min). Three patients required orotracheal intubation for 12 or 24h after surgery, and no reintubation or tracheotomy was required in this series. Symptoms such as stridor and inspiratory retraction were resolved approximately 72 h after surgery, but wheezing was generally resolved at a later time point. One year later, no respiratory symptom was noted in these patients, and endoscopic examination revealed a sufficient glottis opening.
  
  
  CONCLUSIONS
  Surgical removal with a microdebrider is advantageous as a routine surgical technique for small and moderate pediatric subglottic hemangioma.
