术后1 ~2月复查P SG，各项指标：AHI、最低血氧饱和度、最长呼吸暂停时间等，较术前有明显改善。
In 1 ~ 2 months after surgery, PSG were checked again: AHI, the lowest oxygen saturation, the longest time of apnea were improved than those of pre-operation.
结果：本组患者治疗前后最长呼吸暂停时间、呼吸暂停低通气指数（AHI）、睡眠时最低血氧饱和度比较均有显著性差异（P<0.01）。
Results: The significant difference was found in the comparison of the longest time of apnea, AHI and the lowest oxygen saturation of blood in sleep before and after treatment (P<0.01).
