title: [A study of modified lateral pharyngoplasty for the treatment of obstructive sleep apnea hypopnea syndrome: primary outcomes analysis].
abstract: OBJECTIVE
  To describe a modified lateral pharyngoplasty with partial transsection of levator veli palatine muscle in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and report the primary outcomes.
  
  
  METHODS
  Retrospective review was performed in sixty patients with OSAHS. All the patients underwent modified surgical procedures, including partial transsection of levator veli palatine muscle and high soft palatoplasty.
  
  
  RESULTS
  The patients with a reduction of the AHI at least 50% were 6 (6/60, 10%). The patients with a reduction of the AHI at least 50% and a postoperative AHI < 20 were 44 (44/60, 73.3%). The patients with a postoperative AHI < 5 were 10 (10/60, 16.7%). Postoperative complications were postoperative bleeding in two cases (3.3%) and short-term velopharyngeal insufficiency in 10 cases (16.7%).
  
  
  CONCLUSIONS
  Lateral pharyngoplasty with partial transsection of levator veli palatine muscle provides a safe and effective procedure for selected OSAHS patients with oropharyngeal collapse as the main site.
