面神经瘫痪在中老年人群中多发,面神经减压可以有效减少损伤、加快痊愈。但是由于面神经所处位置结构复杂、且面神经个体差异较大,所以,虽然面神经减压术很常用,但手术入路的设计还是不尽人意。尤其是对垂直段的减压术,术中需要磨除乳突,导致患者愈合慢、术后还需乳突重建等,得不偿失。本研究拟通过探讨中老年面神经解剖位置,提出新的可行的手 Facial paralysis in the elderly in multiple, facial nerve decompression can effectively reduce the injury and speed recovery. However, due to the complex structure of the facial nerve and the large individual facial nerve, facial nerve decompression is commonly used, but the design of the surgical approach is still not satisfactory. In particular, the decompression of the vertical segment, intraoperative need to remove the mastoid, leading to patients with slow healing, postoperative mastoid reconstruction, etc., not worth the candle. This study intends to explore the anatomical location of the facial nerve in the middle-aged and elderly to propose new feasible hands
