Audiometric and Patient-Reported Outcomes in Single-Sided Deafness Cochlear Implant Recipients Using the CIQOL-35

Area of Science:

• Audiology
• Neurosurgery
• Otolaryngology

Background:

• Single-sided deafness (SSD) presents unique challenges in auditory perception and daily functioning.
• Cochlear implantation (CI) is a treatment option for severe to profound hearing loss, but its impact on SSD requires specific investigation.

Purpose of the Study:

• To evaluate the effects of cochlear implantation (CI) on audiometric outcomes and quality of life (QOL) in patients with single-sided deafness (SSD).

Main Methods:

• A retrospective case review was conducted at a tertiary university hospital.
• Preoperative and postoperative AzBio speech perception scores and Cochlear Implant Quality of Life-35 (CIQOL-35) Profile scores were analyzed for 17 SSD patients with unilateral CI.
• Postoperative results were compared to a control group of non-SSD CI recipients.

Main Results:

• SSD patients showed a significant improvement in postoperative AzBio quiet scores (median 76% vs. 3% preoperatively, p < .01).
• Statistically significant improvements were observed in CIQOL-35 subdomains including Entertainment, Listening Effort, Social, and Global scores (p < .05).
• Postoperative QOL scores for SSD patients were comparable or superior to age-matched non-SSD CI recipients in most domains.

Conclusions:

• Cochlear implantation (CI) leads to substantial gains in speech perception for individuals with single-sided deafness (SSD).
• CI significantly enhances multiple quality of life (QOL) domains in SSD patients, as measured by the CIQOL-35.
• The CIQOL-35 is a validated instrument for assessing QOL improvements in CI recipients, including those with SSD.
