Surgical Anatomy of Vertical Section of Facial nerve and Its Surrounding Structures
摘要
Abstract
Objective To study the anatomy of the vertical section of the facial nerve. Methods This study was con-ducted using 30 cadavers (27 formalin-fixed cadavers and 3 fresh cadavers) whose facial nerves were dissected bilaterally un-der an operative microscope via a translabyrinthine or facial recess approach. The topographical features of the facial nerve and its relationship with surrounding structures were studied. Results The length of the vertical section of the facial nerve was 16.31+1.29 mm. The distance from the vertical section of the facial nerve to the posterior semicircular canal, osseous ex-ternal auditory canal opening, the jugular bulb, the posterior wall of the external, and the sigmoid sinus were 2.65±0.85 mm, 17.28 ± 1.09 mm, 4.67 ± 0.39 mm and 6.42 ± 2.65 mm, respectively. The frequency of air cells lateral to the facial recess was 88.33%, with a separation of 0-2mm. Abundant blood vessels were seen near the facial nerve canal, likely providing rich blood supply to the nerve, The pyramidal eminence was slightly medial to the facial nerve canal. The facial nerve vertical sec-tion lied anterior and slightly medial to the front end of the digastric crest. The tail of the tympanomastoid fissure was near the facial nerve vertical section. Conclusions Structure s like the air cells lateral to the facial recess, pyramidal eminence, crest of the digastric and tympanomastoid fissure can be helpful in locating the vertical section of the facial nerve. Repeated train-ing and practice and careful observation of the change in bone texture and color while approaching the vertical section are all important in correctly locating the facial nerve.关键词
