Topic: Efficacy of Cochlear Implantation in Neurofibromatosis type 2 Related Hearing Loss
Neurofibromatosis type-2 (NF2) is an autosomal dominant genetic condition resulting in multiple benign central nervous system (CNS) tumors, including the hallmark finding of bilateral schwannomas of the vestibulocochlear nerves (AKA vestibular schwannomas). Hearing loss is a near universal symptom for these patients due to tumor induced derangement of auditory nerve fibers, the effect of CNS tumor treatment or both. Due to the nature of the induced hearing losses, aural preservation / rehabilitation has required non-traditional strategies including auditory brainstem implantation. Additionally, the retrocochlear mechanisms of NF-2 hearing losses precluded consideration of cochlear device implantation. Recent data, including work from the University of Wisconsin Cochlear Implant Program, demonstrating that cochlear implantation is an effective aural rehabilitation option will be discussed.
