Microsurgical anatomy and clinical application of cochlear implant via facial recess approach
摘要
Abstract
Objective To study the anatomy of facial recess and to perform cochlear implantation via facial recess approach.Methods Thirty (60 sides) temple bone specimens were dissected to observe the dimension, shape and variation of the facialrecess.Cochlear implants were performed in 10 patients with severe sensor neural hearing loss via facial recess approach.Results Distance between the second genu of facial nerve and tympanichordal eminentia was 5.29± 0.42mm.Distance between vertical segment of facialnerve and chorda tympaninerve at level of round windowwas 2.95± 0.23mm.Distance between vertical segment of facial nerve and chorda tympani nerve at level of oval window was 3.84± 0.25mm.Distance between pyramidal eminence and round window was 3.71 ± 0.15mm.Distance between pyramidal eminence and oval window was 1.23± 0.10mm.Distance between round window and vertical segment of facial nerve was 3.82± 0.31mm.Distance between round window and oval window was 1.91± 0.16mm.The cochlear implant electrodes were inserted successfully in 10 patients.The facialnerve function were normal in all cases postoperatively.Conclusion Important anatomical landmarks of facial recess approach include round window, oval window, pyramidal eminence, facial nerve, chorda tympani nerve and lateral semicircular canals, which are essential for insertion of cochlear implant electrodes.关键词
