Objective　To explore surgical treatment methods we analyse OSAHS cases of inpatien department.　Methods　40 cases underwent 3 different surgical treament methods.  According to surgerical methods， 40 cases were divided into 3 groups: low temperature coblation-assisted uvunlopalatopharyng oplasty (first group, 24 cases), low temperature coblation-assisted uvunlopalatopharyngoplasty and nasal endoscopic surgery at one time (second group, 8 cases), low temperature coblation-assisted uvunlopalatopharyngoplasty and nasal endoscopic surgery at two times (third group, 8 cases). Patient charts were reviewed and preoperative and postoperative apnea-hypopnea index 3 months after the surgery (AHI), minimum oxygen saturation were evaluated.　Result　In the first group， the effect was successful in 3cases, excellent in 15 cases, good in 6 cases. In the second group， the effect was successful in 6 cases, excellent in 2 cases. In the third group before second operation， the effect was excellent in 2 cases, good in 4 cases and useless in 2 cases. After the second operation， the effect increased to bieng successful in 6 cases, excellent in 2 cases.　Conclusions　A significantly high operation success rate can be expected after surgical correction with low temperature coblation-assisted uvunlopalatopharyngoplasty for soft palate obstruction after whereas a low operation success rate can be found in the third group before their second operation. Both low temperature coblation-assisted uvunlopalatopharyngoplasty and nasal endoscopic surgery are needed when nasal and palate obstructions are present.
