BACKGROUND: The aim of this study was to survey the knowledge and treatment management practices for single-sided deafness (SSD) among different subspecialties of otolaryngology.

METHODS: A questionnaire was sent via Google Sheets to members of the Turkish and Egyptian Otorhinolaryngology Societies between December 2021 and February 2022. For the statistical analysis, the respondents were divided into 3 groups as otologists, non-otologists, and residents at the department of otolaryngology—head and neck department.

RESULTS: There were no statistically significant differences between otologists and non-otologists in radiological imaging (child P = .469, adult P = .140) and preferred treatment method (child P = .546, adult P = .106). However, otolaryngologists showed significant differences in radiologi- cal evaluation (P < .001), vestibular evaluation (P = .000), and frequency of treatment options recommended for pediatric and adult SSD patients (P = .000).

CONCLUSION: There were no significant differences in SSD diagnosis, treatment, and rehabilitation between otologists and non-otologists. However, when comparing pediatric and adult patients, there was a difference in the treatment management of SSD patients.
