This article describes facial reanimation using the transfer of the trigeminal motor nerve branch of the masseter muscle (masseter nerve) to the facial nerve (masseter-to-facial nerve transfer).
A retrospective review was performed of 10 consecutive facial paralysis patients treated with a masseter-to-facial nerve transfer for reanimation of the midface and perioral region over a 7-year period. Patients were evaluated with physical examination, direct measurement of commissure excursion, and video analysis.
All patients regained oral competence, good resting tone, and a smile, with a vector and strength comparable to those of the normal side. Motion developed an average of 5.6 months after masseter-to-facial nerve transfer, with 40 percent of patients developing an effortless smile by postoperative month 19.
The masseter-to-facial nerve transfer is an effective method for reanimation of the midface and perioral region in a select group of facial paralysis patients. The technique is advocated for its limited donor-site morbidity, avoidance of interposition nerve grafts, and potential for cerebral adaptation, producing a strong, potentially effortless smile.
本文描述了使用咀嚼肌的三叉神经运动神经分支（咬肌神经）向面神经（咬肌神经-面神经转移）转移来进行面部再神经支配。
对 10 例连续的面瘫患者进行了回顾性研究，这些患者在 7 年期间接受了咬肌神经-面神经转移术以重新支配中面部和口周区域。通过体格检查、直接测量口角偏移度和视频分析对患者进行评估。
所有患者均恢复了口腔功能、良好的休息张力和微笑，其运动矢量和力量与健侧相当。在咬肌神经-面神经转移术后平均 5.6 个月出现运动，40%的患者在术后 19 个月内出现轻松的微笑。
咬肌神经-面神经转移术是一种有效的方法，可用于选择性面瘫患者的中面部和口周区域的再神经支配。该技术的优点在于供区损伤较小，避免了神经移植，且具有潜在的大脑适应能力，产生有力且可能无需用力的微笑。
