title: [Snoring/sleep apnea--surgically curable].
abstract: BACKGROUND
  Obstructive sleep apnea (OSA) is characterized by nocturnal collapsing of the upper airways. Nasal continuous positive airway pressure (nCPAP) ventilation is the gold standard in the treatment of obstructive sleep apnea syndrome (OSAS). Long-term compliance rates do not exceed more than 60 to 70%. Alternative multi-level surgeries are of interest, combining procedures at the level of the base of tongue and the soft palate in order to stabilize the airway. Preliminary results suggested the hyoid suspension as one part of the multi-level surgery concept to be of high effectiveness. Therefore this study investigated the outcome of the hyoid suspension and compared it with the CPAP therapy.
  
  
  METHODS
  Between March 2001 and February 2003, 66 patients with OSA were treated with a hyoid suspension in combination with surgeries at the base of tongue, the soft palate or the nose (always performed by the same surgeon). All patients underwent a pre- and postoperative polysomnography in the sleep lab. Daytime sleepiness was assessed using the Epworth Sleepiness Scale (ESS). Mean age was 52,1 years, the mean body mass index (BMI) was 28,04 kg/m(2).
  
  
  RESULTS
  The mean apnea-hypopnea-index (AHI) was 38,9121,10/h before operation and 19,25+/-19,64/h after operation (p<0,0001). More statistically significant changes were found for the arousal index, the oxygen saturation and the ESS (p<0,05). After surgery 57,6% of the subjects (38/66) were regarded as cured (reduction of AHI > or =50% and below 15/h). Another 21,2% (14/66) improved (reduction of AHI >20%). Altogether 78,8% of the patients were counted as responders.
  
  
  CONCLUSIONS
  Multi-level surgeries based on the hyoid suspension show the effectiveness of this concept. This surgical strategy could be equal to the CPAP mask, especially in cases of CPAP intolerance.
