![]() ![]() ![]() This report is further supported by a systematic review of published studies that investigate outcomes of CI use on measures of speech recognition in quiet and noise, sound source localization, tinnitus perception, and quality of life for this patient population. The initiative to develop this consensus report was through the American Cochlear Implant Alliance whose board recommended field experts to participate in a task force on SSD. The present report reviews the current evidence relevant to the assessment and management of adults with SSD and offers recommendations based upon expert consensus from clinicians and scientists in the fields of audiology and neurotology. There are additional medical and audiologic considerations for the clinical assessment and management of adult cochlear implant (CI) candidates and recipients with SSD as compared to adults with bilateral hearing loss. FDA-approved indications for cochlear implantation currently define SSD as a four-frequency pure-tone average (4PTA.5, 1, 2, and 4 kHz) of >80 dB HL in the impaired ear and ≤30 dB HL in the contralateral ear ( U.S. The indications for cochlear implantation in the United States expanded in 2019 to include individuals 5 years of age and older with profound sensorineural hearing loss in the impaired ear and normal hearing (NH) in the contralateral ear, known as single-sided deafness (SSD U.S. Expert consensus and systematic review of the current literature were combined to provide guidance for the clinical assessment and management of adults with SSD. A systematic review was also conducted on published studies that investigated outcomes of cochlear implant use on measures of speech recognition in quiet and noise, sound source localization, tinnitus perception, and quality of life for this patient population. The present report reviews the current evidence relevant to the assessment and management of adults with SSD. There are additional considerations for the clinical assessment and management of adult cochlear implant candidates and recipients with SSD as compared to conventional cochlear implant candidates with bilateral moderate to profound sensorineural hearing loss. The indications for cochlear implantation have expanded to include individuals with profound sensorineural hearing loss in the impaired ear and normal hearing (NH) in the contralateral ear, known as single-sided deafness (SSD). ![]()
