This observational study evaluates the effects of cochlear implantation in patients with deafness in one ear.
Cochlear implant (CI) technology has been widely used for individuals with bilateral sensorineural hearing loss to improve the ability to perceive sound by bypassing the damaged portion of the inner ear. Recently in the U.S., Cochlear implantation has also been approved by the FDA for treatment of single-sided deafness. By restoring binaural hearing, cochlear implantation in unilateral hearing loss may improve hearing in noise and sound localization, however its audiologic outcomes and quality of life impact for patients remain incompletely understood. This study aims to establish a prospective database to track and quantify the change in general health status, tinnitus severity, spatial hearing ability, and difficulty with communication in noise after unilateral cochlear implantation in patients with SSD undergoing routine medical and audiologic evaluation at the Johns Hopkins Cochlear Implant Center. Study participants will complete survey questionnaires and undergo standard-of-care audiological evaluation before and after cochlear implantation. Data collected in this study will be invaluable in gaining an in-depth understanding of the effects of cochlear implantation in patients with SSD in the context of current FDA guidelines, and lead to better counseling and patient selection for this treatment modality.

Change in Speech recognition in quiet
Change in Speech recognition in quiet will be assessed using the percent correct on Consonant-Noun-Consonant words and phonemes.
Time frame: Baseline and up to 1 year post-implantation
Change in Speech recognition in noise
Change in Speech recognition in noise will be assessed using the percent correct on AzBio with multitalker babble at 8dB signal-to-noise ratio.
Time frame: Baseline and up to 1 year post-implantation
Change in Spatial hearing as assessed by the Spatial Hearing Questionnaire
Score on Spatial Hearing Questionnaire. Range: 0-100. Higher score signifies less handicap related to sound localization.
Time frame: Baseline and up to 1 year post-implantation
Change in Tinnitus handicap as assessed by the Tinnitus Handicap Inventory
Score on Tinnitus Handicap Inventory. Range: 0-100. Higher score signifies more handicap due to tinnitus.
Time frame: Baseline and up to 1 year post-implantation
Change in Hearing aid benefit as assessed by the Abbreviated Profile of Hearing Aid Benefit
Score on Abbreviated Profile of Hearing Aid Benefit. Range: 0-100. Higher score signifies more frequent problems with hearing.
Time frame: Baseline and up to 1 year post-implantation
Change in Health utility as assessed by the Health Utility Index
Score on Health Utility Index. Range: 0-1.0. Lower score signifies lower health utility.
Time frame: Baseline and up to 1 year post-implantation
