ABSTRACT
Migraine is a relatively common neurological disorder. Neuro-otological symptoms were common in patients with migraines. The aim of this work is to identify the frequency of neuro-otological affection in migraine. The study includes forty-one patients with migraine, and 20 healthy volunteers. Each subject was submitted to full neurological, medical and audiological history and examination. Puretone audiometry, electronystagmography [ENG] tests, auditory brain stem response [ABR] and event related potentials [ERPs]. Dizziness was recorded in 56.1%, rotational vertigo in 31.7% and positional vertigo was occurred in 19.5%. Sense of imbalance, tinnitus and phonophobia were reported in 12.2%, 19.5%, and 29.3%, respectively. Abnormalities in at least one of ENG tests were found in 75.6% of patients that include abnormal results of positioning and positional in 34.1%, post head shaking test in 26.8%, saccade test in 19.5%, optokinetic test in 19.5%, pursuit test in 14.6%, unilateral caloric weakness test in 9.8% and spontaneous nystagmus test in 2.4%. Sensorineural hearing impairment was reported in 21.9%. Significant prolongation of mean interpeak latency of I-III of right ear at 90 dBHL with low repetition rate, III-V at 90 dBHL with high repetition rate and absolute latency of right wave V at 90 dBHL repetition rate compared with controls. No significant differences between patients and control in ERPs. Vestibular dysfunctions were frequently associated with common migraine also hearing impairment was reported in appreciable numbers of cases. Both central and peripheral vestibular affection were recorded in between attacks
