title: [Suspension with repose system in the treatment of obstructive sleep apnea-hypopnea syndrome].
abstract: OBJECTIVE
  To introduce the treatment of severe obstructive sleep apnea-hypopnea syndrome (OSAHS) with Repose bone screw system and to evaluate the treating effect.
  
  
  METHODS
  Thirty-two patients with severe OSAHS (Friedman classification II, III) were treated with tongue ablation + uvulopalatopharyngoplasty + hard palate shortening + Repose suspension. All patients were followed-up for 6 months. Apnea hypopnea index (AHI), lowest oxygen percent saturation (LSaO₂), body mass index (BMI), vallecula epiglottic-lateral pharyngeal wall (V-LPW) and pharyngeal airway space (PAS) were used for the diagnosis and evaluation.
  
  
  RESULTS
  The AHI in 32 patients reduced from (78.3 +/- 11.6)/h to (18.4 +/- 12.5)/h (x(-) +/- s), t = 13.5, P = 0.000. The LSaO₂ increased from (0.632 +/- 0.007) to (0.794 +/- 0.006), t = 4.1, P = 0.000. The BMI was statistical indiscriminate. The V-LPW increased from (12.1 +/- 3.2) mm to (16.9 +/- 2.6) mm (t = 2.5, P = 0.014). PAS increased from (9.2 +/- 3.3) mm to (15.6 +/- 2.4) mm (t = 7.6, P = 0.000). The total effective rate was 93.8%. Three genioglossus stabilization patients complained about foreign body sensation in the mouth floor 3 - 7 days after procedures, which disappeared in 6 months. One genioglossus stabilization patients complained about mandibular osteomyelitis 3 months after procedures, which recovered after anti-inflammatory treatment for 5 days. One genioglossus stabilization patients appeared hypoglossia bleeding, which stopped after compression. One hyoid suspension patients showed haematoma of submandibular region and cured after incision and drainage.
  
  
  CONCLUSIONS
  Repose system was an effective method, safe, simple, with few complications.
