title: Minimally invasive single-stage multilevel treatment for obstructive sleep apnea/hypopnea syndrome.
abstract: OBJECTIVE
  To assess subjective and objective improvement after single-stage multilevel minimally invasive treatment for obstructive sleep apnea/hypopnea syndrome (OSAHS).
  
  
  METHODS
  A retrospective review of a prospective dataset of patients treated in a tertiary care referral center.
  
  
  METHODS
  Charts of 145 patients with mild/moderate OSAHS treated with a single-stage multilevel minimally invasive technique were reviewed to abstract pre- and posttreatment symptoms and polysomnographic data. One hundred twenty-two patients had minimum follow-up of 6 (range, 6-23) months and complete data available for analysis. All patients studied had three-level treatment that included nasal surgery, palatal stiffening by Pillar implant technique, and radiofrequency volume reduction of the tongue base. Primary outcomes included change from baseline in apnea/hypopnea index (AHI). Secondary outcomes included change in Epworth Sleepiness Scale (ESS) and bed-partner assessed snoring visual analogue scale (VAS, 0-10), pain levels, narcotic use, and complications.
  
  
  RESULTS
  Mean AHI decreased from 23.2 +/- 7.6 preoperatively to 14.5 +/- 10.2 postoperatively (P < .0001). Classical "cure" was achieved in 54 (47.5%) patients. Mean ESS decreased from 9.7 +/- 3.9 preoperatively to 6.9 +/- 3.3 postoperatively (P < .0001). Mean snoring VAS decreased from 9.4 +/- 0.9 preoperatively to 3.2 +/- 2.4 postoperatively (P <. 0001).
  
  
  CONCLUSIONS
  Polysomnographic respiratory parameters, ESS, and snoring VAS significantly improved in patients with mild/moderate OSAHS treated with single-stage multilevel minimally invasive surgery. Multilevel minimally invasive single-stage surgery is a valid option for selected patients with mild/moderate OSAHS with the understanding that they may require secondary treatment.
