癫痫之外夜间舌咬伤：睡眠相关面颌肌阵挛——诊断与治疗的挑战
Nocturnal tongue biting beyond epilepsy: sleep-related facio-mandibular myoclonus -a diagnostic and therapeutic challenge.
摘要(中文译文)
我们报告一例睡眠相关面颌肌阵挛（FMM）病例，患者为一名20余岁男性，在入睡期反复出现咬舌发作。视频多导睡眠图和视频脑电图显示下颌肌阵挛性抽动，未见癫痫样活动。发作与应激有关，经氯硝西泮及非药物干预后改善。本病例提示睡眠相关FMM是睡眠相关咬舌的一种罕见且认识不足的病因，有别于癫痫和磨牙症。通过神经生理学检查早期诊断对于防止误诊和确保准确治疗至关重要。
Abstract
We present a case of sleep-related facio-mandibular myoclonus (FMM) in a man in the third decade of life with recurrent tongue-biting episodes during sleep onset. Video-polysomnography and video-electroencephalogram revealed myoclonic jaw jerks without epileptiform activity. The episodes were associated with stress and improved with clonazepam and non-pharmacological interventions. This case highlights sleep-related FMM as a rare, under-recognised cause of sleep-related tongue biting, distinct from epilepsy and bruxism. Early diagnosis through neurophysiological studies is crucial to prevent misdiagnosis and ensure accurate treatment.
