RESUMO
OBJECTIVE@#To investigate the effect and clinical value of simultaneous multiple plane operations in treating severe OSAHS.@*METHOD@#The clinical data of 93 patients with severe OSAHS were retrospectively analyzed. According to different obstruction plane, all the patients were performed different multiple planes of operations. Operations were finished in the same term. All patients underwent PSG examination before operation and 6-month, 1 year after surgical treatment separately.@*RESULT@#No severe complication occurred. According to the assessment guidelines, the response rate was 100% in 6-month and 91.40% in 1-year respectively.@*CONCLUSION@#Most OSAHS have multi-level obstructions in upper airway caliber, such as nasal, nasopharyngeal, velo-pharyngeal and tongue-pharyngeal obstruction. Simultaneous multiple plane operations which based on multiple plane obstruction can improve curative effect.
