SMC评分系统在面肌痉挛病人术前评估的价值

摘要

Objective To explore the value of Samsung Medical Center (SMC) grading system in preoperative evaluation for hemifacial spasm patients. Methods Clinical data of 46 patients with hemifacial spasm were analyzed respectively, who received microvascular decompression. The SMC grading system was used before surgery, and the nerve indentation and distribution of offending vessels were recorded during the surgery. Results SMC grade was positively correlated with nerve indentation (r=0.53, P<0.01). Higher SMC grade was closely related to more offending vessels. Conclusions SMC grading is an effective and safe predictive method for hemifacial spasm and of a certain reference value for the surgeons.%目的：探讨SMC （Samsung Medical Center）评分系统在面肌痉挛（HFS）病人术前评估的价值。方法回顾性分析采用微血管减压术（microvascular Decompression，MVD）治疗的46例原发性面肌痉挛病人的临床资料，术前采用SMC量表进行评分，术中记录神经压痕和责任血管分布情况。结果术前SMC评分与术中神经压痕呈正相关（r=0.53，P＜0.01）。且随着SMC评分级别的升高，术中发现多根责任血管的概率也增大。结论 SMC评分是面肌痉挛微血管减压术有效、安全的预判方法，对术者有一定参考价值。
