Methods For gain optimal operation outcome,we used prolong carved mandible angle osteotomy by intraoral approach.we extended osteotomy line to mental nerve.and mental tuber was scoured,Augmentation chin or genioplasty was performed if the patient was subject to microgenia.

为获得更好的术后效果，我们采用口内入路下颌角弧形截骨术，将弧形截骨线延长到颏神经处，并对颏结节进行打磨，使截骨线延续流畅，伴小颏者同时行隆颏或颏截骨前移。

The bone width of mandibular angle shortened (7.69 ± 0.89) mm; the soft tissue width of mandibular angle shortened (5.13±1.19) mm; the both gonial angle increased (5.68±1.43)° and (5.91±1.66)°, respectively. Applied to actual surgery procedure, the operation time shortened and precision of operation was improved.

结果提示，计算机三维重建及模拟技术有助于揭示下颌角肥大截骨后骨及软组织变化的规律，是模拟手术并选择手术方案的良好辅助手段。

The face is paralytic can happen at all ages, but 15~45 year old the commonnest, come on the peak is reached inside over number hour or 1~3 D, can incline the head unhealthily at the beginning of disease or ache after mandible horn, expression breaks down for flesh of a side countenance, frontal grain disappears, the eye is cracked greaten or close faint, when closing a key point, eyeball up foreign and rotational, show white sclerotic, call Bell the phenomenon, channel of ill side nose lip becomes shallow, quarrel prolapse, side of crooked Xiang Jian of the quarrel when grinningly, rouse cheek or whistle hourglass is enraged, the food when taking food often stops to age at ill side buccal between, at the same time companion has weep reach salivate.

Methods The operations of angle-splitting ostectomy have been performed on 13 patients (11 female, 2 male) who had large, squarish, or broad face with eversion mandibular angle.

对下面部宽大，下颌骨体肥厚，下颌角外翻明显的&四方脸&者(13例，其中男性2例，女性11例)进行了下颌骨体部的劈裂截骨术和部分咬肌去除术。

Objective The conventional simple angle ostectomy sometimes could not get good result for the cases of overwide facial appearance.To reduce the width of the lower face effectively,the angle-splitting ostectomy hasbeen performed.

目的 下面部过宽采取单纯下颌角截骨有时不能取得理想的效果，正确选择适应证进行下颌骨体劈裂截骨术可取得更好的手术效果。
