作者对因肿瘤切除或外伤所致的面颊部缺损,提出应用后头皮皮瓣转移修复,因为颈项部皮肤的纹理,质地,毛发分布与修复后的面部外形等均较其他方法优越。后头皮皮瓣是以头皮为蒂转移颈项部皮肤与皮下组织以修复面颊部缺损。其切口为自头部正中线延伸到颈中线,另一切口则自耳后区沿斜方肌前缘向下,止于耳垂下方3.5～4时或发际下2.5时左右处。皮瓣的分离应带有脂肪与料方肌及项头肌下的筋膜组织,到上项线时头皮瓣开始由于帽状腱膜下的疏松蜂窝组织之故更易分离,此时可遇到枕动脉的穿通枝。如要增加皮瓣的长度,切口应在中线处延伸,避免损伤帽状腱膜下的
The author of the cheek defect due to tumor resection or trauma, the proposed application of scalp flap transfer and repair, because the neck skin texture, texture, hair distribution and repair of the facial contour are superior to other methods. Posterior scalp flap is the scalp pedicle transfer of the neck skin and subcutaneous tissue to repair cheek defect. The incision extends from the midline of the head to the midline of the neck, and the other incision goes down from the frontal area of the tragus to the front of the trapezius muscle. The incision is only 3.5 to 4 o'clock below the earlobe or about 2.5 o'clock in the hairline. The separation of the flap should be with fat and the material under the fascia and the fascia under the head muscle, the head line to the start of the head flap due to subgaleal lobule loose honeycomb tissue is easier to separate, this time meet Penetration to the occipital artery. To increase the length of the flap, the incision should extend at the midline to avoid damage to the subgaleal
