Abstract
|
|
|
|
Patients with neurofibromatosis type 2 (NF2) develop bilateral vestibular schwannomas that can cause binaural progressive hearing loss in most individuals. Auditory rehabilitation for bilateral profound sensorineural hearing loss in patients with NF2 poses a great therapeutic challenge. An auditory brainstem implantation may be an option after tumor excision, but its hearing results are still relatively unsatisfactory. A cochlear implantation (CI) may be another option in those cases where the cochlear nerve has been left intact after tumor excision or in those cases that have been kept stable after treating with Gamma-Knife. Here we report a case of undergoing CI after having been treated with Gamma-Knife in NF2 and showing improved open-set speech perception.
