用肌肉移植法治疗区域性面瘫始于Lexer(1867)。氏首先经口腔行嚼肌移植术,但由于术中常规切断嚼肌神经供应而导致术后嚼肌萎缩,面部无协调动作和咀嚼时面部运动过度。Brunner(1926)将嚼肌缝合于颊粘膜,得到局部支撑。由于忽视肌肉神经的作用,移植的嚼肌与口轮匝肌互不协调。本文介绍经口腔嚼肌移植于口角区面瘫的整形。术前须了解面瘫的程度和区域,然后在患侧作出与健侧相对称的唇颊线定位。术中先在面部作两外侧切口,各长1cm。一个切口位于口唇蚓部边缘下外侧,另一切口位于唇颊线和上唇蚓部边缘连线之中点。口内手术是在下颌前外面作一
Treatment of regional facial paralysis with muscle transplantation begins with Lexer (1867). Shi's first oral muscle chewing muscle transplantation, but due to the usual cut off during the operation of the masseter muscle nerve supply resulting in postoperative chewing muscle atrophy, facial uncoordinated movements and facial hyperactivity during chewing. Brunner (1926) stitches the chewing muscle to the buccal mucosa to gain partial support. Due to the neglect of the role of the muscle nerves, the implanted masseter muscle and the orbicularis muscle disharmony. This article describes the oral masseter muscle transplantation in the mouth area paralysis plastic surgery. Before surgery to understand the extent and area of facial paralysis, and then make the opposite side of the contralateral healthy lip cheek line positioning. Surgery in the first two lateral incision for the face, each 1cm long. One incision lies outside the vermis of the vermis and the other incision is midway between the verge line of the labia and the vermis of the upper vermis. Oral surgery is done in front of the mandible
