The aim of present study is to describe the use of the endoscopic assisted cochlear implant approach in cases with severely malformed temporal bones and with anomalous anatomy of the inner ear and tympanic cavity. Eight patients with malformed middle and inner ear and bilateral profound hearing loss were operated using an endoscopic assisted cochlear implant procedure at our tertiary university referral center between January and September 2013. Five patients received a cochlear implant using a suprameatal endoscopic assisted approach. A chart review of clinical data and videos from the operations was performed. All procedures were re-analyzed and codified. In all patients, discharge from hospital was on the third day post-surgery. No immediate or late postoperative complications were noted. The current mean follow-up is 6 months, with range between 4 and 12 months. This approach proved to be successful in cochlear implant placement. It guaranteed a very good control on the facial nerve, even in cases with difficult anatomical conditions, mainly thanks to the endoscopic procedure. It also permitted an appropriate anatomical orientation of the abnormal middle ear with a direct safe cochleostomy, when the round window position would have been difficult to treat using a traditional approach.

Abstract

The aim of present study is to describe the use of the endoscopic assisted cochlear implant approach in cases with severely malformed temporal bones and with anomalous anatomy of the inner ear and tympanic cavity. Eight patients with malformed middle and inner ear and bilateral profound hearing loss were operated using an endoscopic assisted cochlear implant procedure at our tertiary university referral center between January and September 2013. Five patients received a cochlear implant using a suprameatal endoscopic assisted approach. A chart review of clinical data and videos from the operations was performed. All procedures were re-analyzed and codified. In all patients, discharge from hospital was on the third day post-surgery. No immediate or late postoperative complications were noted. The current mean follow-up is 6 months, with range between 4 and 12 months. This approach proved to be successful in cochlear implant placement. It guaranteed a very good control on the facial nerve, even in cases with difficult anatomical conditions, mainly thanks to the endoscopic procedure. It also permitted an appropriate anatomical orientation of the abnormal middle ear with a direct safe cochleostomy, when the round window position would have been difficult to treat using a traditional approach.
