Functional Impact of Psychological Symptoms in Patients With Superior Semicircular Canal Dehiscence Syndrome (SSCD): a National Cross-sectional Study

Superior semicircular canal dehiscence syndrome (SSCD), also known as Minor syndrome, is a rare otoneurological condition characterized by auditory and vestibular symptoms. Emerging evidence suggests a significant psychological burden, including anxiety, depressive symptoms, and suicidal ideation, potentially related to diagnostic delay and chronic symptomatology. However, no structured epidemiological study has systematically assessed quality of life and psychological symptoms in this population. The aim of this study is to evaluate quality of life and associated psychological symptoms in adults reporting a diagnosis of SSCD using validated self-reported questionnaires in a national cross-sectional survey.

Inclusion Criteria: * Age ≥ 18 years * Self-reported diagnosis of superior semicircular canal dehiscence syndrome * Ability to understand French * Non-opposition to participation Exclusion Criteria: * Refusal of data use for research purposes * Self-reported cognitive impairment preventing questionnaire completion
