Abstract

Objective:This study was designed to distinguish vestibular migraine(VM) from Meniere's disease(MD) by comparing age, sex, family history, audiological and vestibular test results in patients with VM or MD. Method:Forty-six patients with suspected VM, 60 patients with confirmed VM, and 60 patients with confirmed MD were studied. All patients were asked for detailed medical history, and then underwent bithermal caloric test and audiological test. The hearing function and vestibular function were analyzed. Result:①General conditions: the sex ratio with suspected VM, confirmed VM and confirmed MD was 1∶4.75, 1∶5.67 and 1∶1. Family history in these three groups was 80.43%(37/46),66.67%(40/60),6.67%(4/60), respectively. ②In the three groups, the abnormal rates of caloric test were 50.00% (23/46), 31.67% (19/60) and 78.33%(47/60), respectively.③The rate of pure tone audiometry abnormality in the three groups was 60.87% (28/46), 63.33% (38/60) and 100.00% (60/60), respectively. Of 46 suspected VM patients, 18 (39.13%) had high frequency hearing loss, 7 (15.22%) had full frequency hearing loss, and 3 (6.52%) had low frequency hearing loss. Among 60 confirmed VM patients, 18 (30.00%) had high frequency hearing loss, 15 (25.00%) had full...Continue Reading
