Cochlear Implantation for Treatment of Tinnitus in Single-sided Deafness: A Systematic Review and Meta-analysis

Objective: Quantify the benefit of cochlear implantation (CI) for tinnitus relief among individuals with single-sided deafness (SSD). Data Sources: PubMed, Scopus, and Cochrane databases were searched through July 10, 2019. Search strategies used a combination of subject headings (e.g., MeSH in PubMed) and keywords for the following three concepts: single-sided deafness, cochlear implantation, and tinnitus. Study Selection: English articles that reported the preintervention (baseline) tinnitus-related patient-reported outcome measures (e.g., Tinnitus Handicap Inventory [THI] and Visual Analog Scale [VAS] for loudness) in patients with SSD that underwent CI were included. Data Extraction: Number of patients, mean age, etiology of hearing loss, duration of deafness, baseline and follow-up THI and VAS scores. Data Synthesis: A total of 17 studies met inclusion criteria encompassing 247 patients with SSD receiving a cochlear implant (mean age 50.2 yr, range 23–71). For THI, CI resulted in a mean difference of –35.4 points [95% CI –55.8 to –15.0, p
