胫神经腓肠肌肌支离断术治疗小腿腓肠肌肥大

Neurotomy of muscle branch of tibial nerve for gastrocnemius muscle hypertrophy

目的:探讨一种简单、安全、有效的小腿肌肉肥大的治疗方法。方法:选择典型的小腿肌肉肥大病例,静脉+局麻下在腘窝横纹中央切开1.2～1.5cm皮肤、皮下组织,找到胫神经的腓肠肌内、外侧头肌支,用神经探测仪确定后离断。结果:自2005年共完成400例,经6～24个月随访,平均12个月,效果满意,小腿围较术前缩减3.63±1.10cm(P<0.001),不影响小腿功能。结论:本法操作简单、效果明显,病人痛苦小,恢复快,符合美容手术微创的原则。

Objective To explore a simple,safe,effective treatment for calf muscle hypertrophy. Methods Typical patients with calf muscle hypertrophy were chosen. Local and intravenous anaesthesia were used. The incision was in the transverse striation of popliteal fossa. After medial gastrocnemius muscle branch and caput laterale musculi gastrocnemii branch of tibial nerve were found,confirmed with nerve stimulator,the branches were amputated. Results From September 2005,400 patients underwent this operation. In 6～24 months of follow-up,the effect of this operation was satisfied. The calf was minified 3.63 ±1.10cm （P 0.001）. No damage in the leg＇s function. Conclusion The technology of this operation was simply,the effects were satisfied,the patients had little pain and recovered quickly. All of these were according with the principles of aesthetic mini trauma surgery.
