50年代以来,对于腮腺浅叶和位于面神经表面的腮腺良性和低度恶性肿瘤,一般采取解剖面神经的方法,将肿瘤连同腮腺浅叶一并切除。在上述手术中,常根据肿瘤所在部位和移动性,通常采用两种不同方法来解剖面神经:即先找面神经主干,然后再循面神经主干向远端分离分支;或先找面神经分支,再循此而至主干。因此,在腮腺摘除术 Since the 1950s, benign and low-grade tumors of parotid gland lobe and parotid surface located on the surface of the facial nerve generally adopt the method of dissecting the facial nerve to resect the tumor together with the parotid gland shallow lobes. In the above surgery, often based on tumor location and mobility, usually using two different ways to dissect the facial nerve: that is, first find the facial nerve trunk, and then back to the distal trunk of the facial nerve branch; or to find the facial nerve branch, and then follow this And to the trunk. Therefore, parotid excision
