title: Evaluation of submucosal minimally invasive lingual excision technique for treatment of obstructive sleep apnea/hypopnea syndrome.
abstract: OBJECTIVE
  Submucosal minimally invasive lingual excision (SMILE) is a novel approach to address hypopharyngeal obstruction. This study compares the efficacy, morbidity, and complications of this technique to radiofrequency reduction of the tongue base (RFBOT), the current standard in minimally invasive tongue base reduction.
  
  
  METHODS
  Retrospective analysis of data extracted from a prospective database.
  
  
  METHODS
  Ninety-six patients who underwent SMILE (n=48) or RFBOT (n=48) were studied. Efficacy and safety of the procedures were compared on the basis of polysomnography results, morbidity measures, and complications.
  
  
  RESULTS
  Patients in both groups demonstrated a significant reduction in the apnea/hypopnea index. Success rates for SMILE and RFBOT were 64.6 percent and 41.7 percent, respectively (P=0.024). SMILE, however, was associated with increased morbidity and complications.
  
  
  CONCLUSIONS
  In a comparable surgical protocol for obstructive sleep apnea-hypopnea syndrome, SMILE technique for tongue base reduction demonstrated increased efficacy over RFBOT but resulted in more complications. Additional experience with the procedure may reduce complications and increase overall efficacy.
