Report of Endoscopic Cochlear Implantation

Abstract

Endoscopic cochlear implantation may become a viable, safe, and feasible alternative to the standard open transmastoid approach.

Using endoscopy to locate the round window membrane during cochlear implantation: Our experience with 25 patients

“…Several studies in the literature have documented a transcanal endoscopic approach for cochlear implantation . Reported advantages of the transcanal endoscopic approach include avoidance of drilling the mastoid cavity, better visualisation of the round window area and safety of the facial nerve.…”

“…Several studies in the literature have documented a transcanal endoscopic approach for cochlear implantation. 3,8,9 Reported advantages of the transcanal endoscopic approach include avoidance of drilling the mastoid cavity, better visualisation of the round window area and safety of the facial nerve. However, in a recent study that analysed the orientation of the cochlear basal turn in relation to the ear canal, it was demonstrated that the trajectory provided by the conventional posterior tympanotomy aligned more favourably with the cochlear basal turn than the transcanal approach, thus may result in less damage caused by deflection of the electrode array in the scala tympani.…”

Endoscopic cochlear implantation: Call for caution

“…An endoscope will provide a very detailed view of the round window niche and associated anatomy through the ear canal . There have been reports of endoscopic cochlear implant surgery that includes transcanal access and wiring . Reported advantages include better visualization of the round window area, avoidance of drilling the mastoid, and safety of the facial nerve.…”

Endoscopic-Assisted Cochlear Implantation: A Case Series

“…Roughly at similar times, endoscopic cochlear implantation surgery was also reported, although it is a relatively new entity [15][16][17] . Hiraumi et al [17] reported transcanal endoscopic cochlear implantation in temporal bone.…”

“…Hiraumi et al [17] reported transcanal endoscopic cochlear implantation in temporal bone. Dia et al [15] reported 25 cases of endoscopic cochlear implantation with an endoscopic transcanal technique from two different clinics. In this study, an electrode was inserted via a transcanal approach by an endoscope without mastoidectomy.…”
