Preoperative CT Assessment in CI: Dehiscence of the Labyrinthine Segment of the Facial Nerve Causing Facial Nerve Stimulation
Lieke van der Meer; Rutger Hofman; Rolien Free
Excerpt
Cochlear implantation (CI) is indicated in patients with severe sensorineural hearing loss (SNHL). Facial nerve stimulation (FNS) is a complication which occurs after 0.9 to 14% of CI surgery (1). Patients at risk for FNS usually have cochlear malformations, a history of temporal bone fractures, or preexisting otologic diseases, e.g., otosclerosis (2,3). We present an unusual case in which a patient, without preexisting otologic diseases or known anatomic variations, developed FNS due to a dehiscence at the middle cochlear turn.
