Hearing rehabilitation in children with malformed ears: The endoscopic-assisted approach for cochlear implantation

Abstract

BackgroundCochlear implantation (CI) in children with malformed ears can be challenging through the standard surgical technique. Several alternative approaches have been described. The endoscopic-assisted approach can be chosen as an effective and safe surgical technique, overcoming the drawbacks of the traditional approach. MaterialWe further describe a combined technique based on a limited mastoidectomy with no posterior tympanotomy and an endoscopic transmeatal approach to the round window (RW): the electrode is driven from the mastoid to the middle ear through the attic. ResultsThe concomitant endoscopic assistance allows for improved surgical vision, reducing the risk of major complications. The main advantages of this technique are related to better visualization of the RW for safe insertion of the electrode; avoidance of damage to the facial nerve (FN), due to direct visualization, and sparing the posterior tympanotomy; avoidance of subtotal petrosectomy, if not necessary. ConclusionThe purpose of this article, supported with a video file, is to describe step by step this endoscopic-assisted procedure in a patient with middle ear malformation.
