title: [Multiple plane operations in treating severe obstructive sleep apnea-hypopnea syndrome].
abstract: OBJECTIVE
  To investigate the effect and clinical value of multiple plane operations in treating severe OSAHS.
  
  
  METHODS
  The clinical data of 28 patients with severe OSAHS were retrospectively analyzed. All the patients were performed two planes of operations or more as below: submucous nasal septum resection, nasal sinus endoscopy, adenoidectomy, uvulopalatopharyngoplasty (UPPP), tongue base incision, hyoid suspension, tongue base Coblation etc. Operations were finished in the same term or by stages. All patients underwent polysomnography(PSG) examination before operation, and 6-month and 1-year after surgical treatment separately.
  
  
  RESULTS
  No severe complication occurred, the 6-month, 1-year responders are 100% and 89.29% respectively. Both AHI and LSaO2 changed obviously (P < 0.01).
  
  
  CONCLUSIONS
  Most OSAHS have multi-level obstructions in upper airway caliber, such as nasal, nasopharyngeal, velo-pharyngeal and tongue-pharyngeal obstruction. Multiple plane operations which based on idiographic obstruction sites can improve curative effect. Operation project should be established according to the conditions of upper airway and patients' intention.
