Official title
Cochlear Implantation During Vestibular Schwannoma Removal or During Labyrinthectomy Surgery for Treatment of Meniere's Disease
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is a prospective, clinical study to determine if it is safe and effective to use a cochlear implant over time in individuals undergoing removal of a vestibular schwannoma (VS), benign tumor of the hearing and balance nerve or undergoing a labyrinthectomy for treatment of Meniere's disease. Individuals undergoing these surgeries will be deaf on the surgical side after the procedure. Currently, cochlear implants are approved for use and not considered investigational in individuals with hearing loss on both sides. However, use of a cochlear implant for these patient populations (single-sided hearing loss) will be considered a new use of an approved device. Participants undergoing surgery to remove a VS or having a labyrinthectomy will have a cochlear implant inserted after the surgical procedure for clinical care. Approximately 4 weeks after surgery, participants will be fitted with an external speech processor on the surgical side that will stimulate the internal cochlear implant. Participants will return at the following intervals after the initial processor fitting: 2 weeks, 1 month, 3 months, 6 months, 9 months, and 12 months. At each interval, participants will complete questionnaires on how they are hearing with the implant and their quality of life with the implant and be tested on their ability to hear sounds and understand speech. Potential risks are those associated with all cochlear implant surgeries, and include device failure resulting in removal of device, irritation or redness in surgical area and/or area where processor is attached, increased ringing in the ear, facial nerve stimulation and a change in the way speech and other sounds sound through the implant. Potential benefits to individual participants in this study include improvement in detection and speech understanding of the surgical ear. Participants may also experience improved abilities to locate sound and understand speech in noise as the result of having hearing on both sides.
