研究失神经支配的面肌的形态学可能是估计面肌纤维的神经再生能力的一种方法。据作者所知,以往仅有人研究过失神经支配及神经再生的肢体肌肉的形态学改变,而对表情肌的形态学及病理形态学则不清楚。作者研究了失神经支配的面肌的17个活检材料,8男7女(有2例各作两个肌肉活检),年龄14～71岁,平均42岁,各有单侧面瘫1个月至36年不等。17个活检标本系于面神经手术时就近 Studying the morphology of denervated facial muscles may be one way to estimate the ability of facial nerve fibers to regenerate. According to the author’s knowledge, in the past, only one person had studied the morphological changes of limb muscles with denervation and nerve regeneration, but the morphology and pathomorphology of the muscles were not clear. The authors studied 17 biopsy materials on denervated facial muscles, 8 males and 7 females (two with two muscle biopsies each) aged 14-71 years (mean, 42 years old) with unilateral paralysis for 1 month to 36 years. 17 biopsy specimens of facial nerve surgery near
