Belfast Cochlear Implant Centre; the surgical results of the first 100 implants

We assess the surgical results of the first one hundred cochlear implant operations at the Belfast Cochlear Implant Centre. This paper is in the form of a retrospective case series, taking into account the surgical technique used and any problems encountered. Initially 28 operations were performed using the standard inverted U-shaped incision. After Gibson and Harrison described a vertical postaural incision we began using a slight modification of this technique for any further implantations. Since November 1994 the vertical post aural skin incision has been used in 71 patients. The surgical complications of cochlear implantation include haematoma, wound infection and flap necrosis of varying degrees of severity. We report a low level of these complications, particularly with the vertical incision.
