目的面神经额颞支在前侧方入路时易受损伤，其损伤后可引起面部畸形。为给临床提供数据，进行此研究。方法对10例（20侧）为颅湿标本的面神经额颞支及额颞区进行巨显微外科解剖，并对其测量和拍照。结果面神经额颞支通常三支，由腮腺和咬肌筋膜穿出后走行于颞浅筋膜浅面、皮下组织深层，且始终在颞浅血管之前。结论为防止面神经额颞支损伤，切口应在颞浅血管后或耳屏前18mm后。在颞深筋膜浅、深两层之间分离，眶颧区同骨膜一起分离。 Purpose Frontal frontal branch of the frontotemporal approach vulnerable to injury, its damage can cause facial deformity. To provide clinical data, the study was conducted. Methods Ten microsurgical anatomy of frontal and frontotemporal areas of the facial nerve in 10 patients (20 sides) with cranial wet specimen was performed and measured and photographed. Results Frontal frontotemporal branch of the facial nerve usually three, by the parotid gland and fascia through the fascia after running in the superficial temporal fascia, subcutaneous tissue deep, and always in the superficial temporal blood vessels. Conclusion To prevent frontotemporal branch of facial nerve injury, incision should be in the temporal superficial blood vessels or after 18mm before the tragus. In the deep temporal fascia shallow, deep separation between the two layers, the orbital zygomatic area with the periosteal separation.
