摘要
目的 :探讨经皮电刺激颏舌肌对阻塞性睡眠呼吸暂停综合征 (OSAS)患者咽腔不同阻塞平面的影响。方法 :对 19例 OSAS患者在纤维喉镜下做 Muller′s动作判定咽腔不同阻塞平面 ,并在不同睡眠夜进行电刺激颏舌肌与未刺激的有关参数对比。结果 :舌后咽 (RTBP)平面狭窄或阻塞 ,所测呼吸紊乱指标均明显下降 (P <0 .0 5 ) ,血氧饱和度显著提高 (P <0 .0 5 ) ,临床症状改善 ;RTBP及腭咽 (PP)多平面混合狭窄和阻塞仅部分指标改善 ;PP平面狭窄或阻塞 ,各指标均无改善 ;影响睡眠的指标无升高。结论 :颌下经皮电刺激对 OSAS有效 ,其效果的差异与咽腔不同的阻塞平面有密切关系 ,RTBP狭窄或阻塞电刺激效果最好 ;
Objective:To investigate the effect of submaxillary transcutaneous electric stimulation of genioglossus on obstructive sleep apnea syndrome (OSAS).Method:Nineteen patients (male) with OSAS were diagnosed by polysomnography previously.Fixed the provocative locus of genioglossus and its controlling nerve with local anatomy.Estimated obstructive level of pharyngeal cavity by observing muller′s maneuver under fiberolaryngoscope.Determined the effects of electric stimulation on different levels of narrow pharyngeal cavity with control study method.Result:The effect of electrical stimulation was different in different narrow level.The best effect was found on the obstruction of retrotongue base pharynx level,data of breath disorder (P< 0.05 ),oxygen saturation (P< 0.05 ) and clinical symptoms were significantly improved. The data were partly improved on multilevel obstrcutions of retrotongue base pharynx or above,no improvement was found on the obstruction of retrotongue base pharynx level.Dormant index was not worse.Conclusion:Submaxillary electrical stimulation is effective to the treatment of OSAS and its curative effect perhaps has a close relationship with obstrcutive level of with upper airway.Further research on the mechanism showed that stimulating upper airway dilating muscle which formed mainly by genioglossus could push the tongue ahead and effectively open pharyngeal cavity.Maybe it is a reason that the best effect took place on the retrotongue base pharynx level.Sleep was not affected by electrical stimulation.
