30例周围性面神经炎住院患者,男20例,女10例。年龄19～65岁(平均43岁)。右面瘫9例,左21例,病程2～4月。采用丹麦产DANTEC 2000C型肌电图机共检查90条面神经分支所支配的肌肉,判断其损伤程度,其中正常8条:肌肉松弛时电静息,轻用力时运动单位电位时限正常,重用力时呈干扰型;轻度部分失神经征18条,肌肉松弛时无或有少量纤颤电位,轻用力时运动单位电压时限正常,有少量多相电位,重用力时呈干扰型;中度部分失神经征40条,肌肉松弛时有较多纤颤电位和正相电位,轻用力时运动单位电压时限正常,多相电位增多,重用力时呈混合型,重度部分失神经征24条,肌肉松驰时有显著纤颤电位和正相电位,轻用力时运动单位减少,多相电位为主,重用力时呈单纯型。 患者在病变早期(2周内)选用超短波疗法,时间20min,无热量,每日2次;4周后选用低频脉冲电刺激或磁脉冲,分别刺激受损神经所支配肌肉,使
30 cases of peripheral facial neuritis inpatients, 20 males and 10 females. Age 19 to 65 years (mean 43 years old). Right paralysis in 9 cases, left 21 cases, duration of 2 to 4 months. The DANTEC 2000C electromyography machine was used in Denmark to check the muscle dominated by 90 facial nerve branches to determine the degree of injury, of which 8 were normal: muscle relaxation, resting, light exercise time unit potential normal, heavy 18 cases of mild denervation, muscle relaxation without or with a small amount of fibrillation potential, light force when the normal motor unit voltage duration, a small amount of multiphase potential, when the force was interference type; moderate part of the loss Neurological sign 40, muscle relaxation when more fibrillation potential and positive phase potential, light force when the motor unit voltage duration is normal, multiphase potential increase, when mixed force was heavy, part of the absence of severe denervation 24, muscle relaxation When there is significant fibrillation potential and positive phase potential, light exercise units decrease, multiphase potential, heavy was pure type. Patients in the early stage of disease (2 weeks) selection of ultrashort wave therapy, time 20min, no calories, 2 times a day; 4 weeks after the choice of low-frequency pulse electrical stimulation or magnetic pulse, respectively, to stimulate the damaged nerve to dominate the muscles
