The Etiological Relationship Between Migraine and Sudden Hearing Loss.

Objectives: To investigate the relationship between sudden sensorineural hearing loss (SSNHL) and migraine, assess the prevalence of migraine in patients with idiopathic SSNHL, and determine a possible common vascular etiopathogenesis for migraine and SSNHL. Study Design: Prospective cohort study. Setting: Tertiary referral center. Patients: This study initially assessed 178 SSNHL cases obtained from the Head and Neck Surgery Clinic patient database at a tertiary hospital in Turkey between January 2011 and March 2016. Ultimately, a total of 61 idiopathic SSNHL patients participated in the present study. Interventions: Diagnostic. Main Outcome Measures: Cases with inflammation in the middle or inner ear; a retro cochlear tumor; autoimmune, infectious, functional, metabolic, neoplastic, traumatic, toxic, or vascular causes; Meniere's disease; otosclerosis; multiple sclerosis; and/or cerebrovascular diseases were excluded. Results: Of the 61 idiopathic SSHNL patients, 34 were women (55.74%); and 24 (39.34%) had migraine, according to the criteria of the International Headache Society (IHS). The mean age of the migraine patients (Group 1) was 43.83 +/- 13.16 years, and that of those without migraine (Group 2) was 51.05 +/- 16.49 years. The groups did not significantly differ in terms of age, sex, or SSNHL recovery rates according to the Siegel criteria (p > 0.05). Ten of the migraine patients experienced visual aura, and the recovery rates of this group were higher. Additionally, the rate of total hearing loss was lower in Group 1 (n = 3, 12.5%) than in Group 2 (n = 10, 27%). Conclusion: SSNHL patients had a higher prevalence of migraine. Although those with migraine had higher recovery rates, the differences were not statistically significant. Copyright (C) 2017 by Otology & Neurotology, Inc.
