在腮腺手术中,医生必须辨清并确定面神经主干的位置以免损伤。根据解剖标志识别面神经主干的方法有多种,但各有优缺点。例如依据鼓乳裂识别面神经干,需翻起耳道周围之骨膜,并向下分离达鼓乳裂,此法使手术操作变得复杂。作者报告一种腮腺手术中识别面神经干的简易新法,该法以乳突前缘和鼓板后缘形成的切迹为标志,此切迹位鼓乳裂最下份。按腮腺手术常规作切口和翻瓣,将胸锁乳突肌前缘和腮腺后缘分离,并后拉肌肉,以食指伸入切口内触摸切迹,在切
In parotid surgery, the doctor must identify and determine the location of the facial nerve trunk to avoid injury. There are several ways to identify facial nerve trunks based on anatomical landmarks, but each has its own advantages and disadvantages. For example, based on the identification of facial cleft rupture of the facial nerve, need to turn the periosteum around the ear canal and the separation of the drum down to the drum, this method makes the operation complicated. The authors report a simple and novel method of identifying facial nerve trunks in the parotid gland surgery that marks the notch formed by the front of the mastoid and the trailing edge of the drum plate. According to the parotid gland surgery for conventional incision and flap, the sternocleidomastoid anterior margin and the parotid gland posterior edge separation, and after pulling the muscles, the index finger extended into the incision touch notch, cutting
