Abstract: Introduction Posterior tympanotomy through facial recess (FR) is the conventional and most preferred approach to facilitate cochlear implantation, especially when the electrode is inserted through the round window. The complications of the FR approach can be minimized by proper understanding of the anatomy of the FR. Objective The present study was undertaken to assess the various parameters of FR and round window visibility, which may be of relevance for cochlear implant surgery. Metho… Show more

“…Variations in the origin of the chorda tympani branch and pneumatisation pattern affect the size of the facial recess. 3 The round window niche is not always fully exposed by posterior tympanotomy. Öztürk et al found that complete round window exposure through the facial recess was possible for most temporal bones (79.2 per cent).…”

“…11,12 Electrodes can become displaced even in patients with normal inner-ear anatomy. In particular, an electrode may be inappropriately directed into the superior or lateral semicircular canal through the vestibule 3,12 or internal auditory canal, or even the internal carotid artery. Electrode misplacement is usually caused by drilling along an inappropriate axis.…”

“…In our study, there were 3 cases with narrow facial recess. Over the literatures, there are great anatomical variations of facial and chorda tympani nerves [10]. To see the RW in such cases, scarification of the chorda tympani may be needed, otherwise an alternative approach has to be used [11].…”
