120例腮腺肿瘤术后面神经功能障碍患者在术后8d、1月、3月、1年进行了面神经功能指数、电诊断及肌电图测定。结果表明,术后8d,患侧面神经功能均有明显的障碍(P<0.05)。术后1月,面神经功能障碍最为严重(P<0.05)。术后3月,患侧面神经功能明显恢复(P>0.05)。术后1年,患侧面神经功能恢复达95％以上。作者观察到:腮腺区肿瘤愈大,手术时间愈长,面神经牵拉愈多,术后术区肿胀愈明显,其面神经功能障碍愈严重。作者并对如何减轻面神经功能障碍进行了讨论。
Facial nerve function index, electrodiagnosis and EMG were measured in 120 patients with facial nerve dysfunction after parotidectomy operation at 8d, 1h, 3month and 1 year after operation. The results showed that 8 days after operation, there were obvious obstacles to the function of the facial nerve (P <0.05). After 1 month, facial nerve dysfunction was the most serious (P <0.05). After 3 months, the function of the affected facial nerve was recovered (P> 0.05). One year after operation, the function recovery of facial nerve reaches more than 95%. The authors observed: the larger the parotid gland tumor, the longer the operation time, the more facial nerve stretch, the more obvious postoperative swelling, the more severe facial nerve dysfunction. The authors also discussed how to reduce facial nerve dysfunction.
