使用口内垂直矢状升支截骨术治疗髁突增生或高位髁突骨折,有较大骨接触面,可以牢固固定。1985~1995年,作者所做的23例截骨术患者中,男性18名,女性5名,年龄15~48岁。 方法 此技术基于治疗下颌前突的截骨术。做类似口内升支垂直截骨术切口后,使用口内乙状切迹拉钩暴露乙状切迹到角前切迹的下颌外侧面,为确认乙状切迹的前份,从喙突上剥离颞肌腱的一部分,伸入口内乙状切迹拉钩保护上颌动脉。用平裂钻在升支外侧份垂直去皮质,从乙状切迹正中到下颌小舌,直到角前
The use of oral sagittal orthopedic lumbar osteotomy in the treatment of condylar condylar hyperplasia or condylar fractures, a larger bone contact surface, can be firmly fixed. From 1985 to 1995, the authors made 23 osteotomy patients, 18 males and 5 females, aged from 15 to 48 years. Methods This technique is based on the osteotomy for the treatment of mandibular protrusion. To do similar oral ascending branch vertical osteotomy incision, the use of sigmoid notch inside the mouth to expose sigmoid notch to the anterior notch of the lateral mandibular incision, in order to confirm the sigmoid notch in the front, from the coracoid process on the peeling Part of the tendon, extending into the mouth sigmoidal notch hook to protect the maxillary arteries. With a flat cracked drill outside the ascending branch of the vertical cortex, from the sigmoid notch to the lower jaw tongue, until the corner
