Percutaneous submental electrical stimulation during sleep may be a new therapeutic method for patients with obstructive sleep apnea syndrome (OSAS). Electrical stimulation to the submental region during obstructive apnea is reported to break the apnea without arousal and to diminish apneic index, time spent in apnea, and oxygen desaturation. The mode of breaking the apnea by electrical stimulation has not yet been shown. However, genioglossus is supposed to be the muscle responsible for breaking the apnea by forward movement of the tongue. To visualize the effect of submental electrical stimulation, one patient with severe OSAS has been examined with videoradiography. Submental electrical stimulation evoked an immediate complex muscle activity in the tongue, palate, and hyoid bone. This was followed by a forward movement of the tongue which consistently broke obstructive apnea without apparent arousal. Time spent in apnea was diminished but intervals between apnea were not affected.
睡眠期间经皮颏下电刺激可能是阻塞性睡眠呼吸暂停综合征（OSAS）患者的一种新治疗方法。据报道，在阻塞性呼吸暂停期间对颏下区域进行电刺激可在无觉醒的情况下打破呼吸暂停，并降低呼吸暂停指数、呼吸暂停持续时间和氧饱和度。电刺激打破呼吸暂停的方式尚未明确。然而，舌颏肌被认为是通过舌头向前运动来打破呼吸暂停的肌肉。为了观察颏下电刺激的效果，对一名重度OSAS患者进行了视频放射成像检查。颏下电刺激立即引起舌头、腭和舌骨的复杂肌肉活动。随后舌头向前运动，持续打破阻塞性呼吸暂停且无明显觉醒。呼吸暂停持续时间缩短，但呼吸暂停间隔未受影响。
