Abstract：Cochlear implantation (CI) is the most effective approach to severe to profound sensorineural hearing loss so far. Since the performance of CI relies on the AN population that encodes and transmits acoustic signals to the higher au-ditory processing stations, strict and comprehensive patient selection, surgical skills, effective rehabilitation training and post-implantation psychotherapy are of great importance for the best effects of CI. Based on the surgical approach, structur-al issues relevant to facial recess access and electrode insertion, such as abnormal mastoid pneumatization, malformation of the ossicular chain, vestibular window, round window or facial canal, anteriorly displaced sigmoid sinus and high jugular bulb, have been studied in order to provide a basis for selection of surgical approaches and evaluation of surgical risks. It is of great significance to reduce complications and improve surgery efficacy.
