Radical cavities and cochlear implantation.
Profoundly deaf patients with chronic suppurative otitis media have been contraindicated for cochlear implantation in the past. Complications such as infection of the radical cavity, fat necrosis, skin flap problems, change in electrode position and cholesteatoma have occurred in subjects with radical cavities. The aim is to create a dry, self-cleansing, infection-free cavity. This is essential in patients about to receive a cochlear implant, as infection may be introduced into the cochlea at the implantation site and destroy any remaining neural elements. The aim of this paper was to show that it is possible to obliterate the radical cavity and perform cochlear implantation using a one-step surgical technique. Eight patients suffering from long-term bilateral chronic middle ear diseases with chronic sepsis leading to severe hearing impairment underwent cochlear implant surgery. No major complications were observed in these subjects.
