A case of Meniere's disease in the left ear and Lermoyez syndrome in the right ear--a 32-month longitudinal observation and literature review.
We here present a 32-month follow-up of a case of Lermoyez syndrome combined with Meniere's disease. The patient was a 49-year-old male, with a stabilized severe hearing loss in the left ear for about 15 years after Meniere's disease. He started to show typical symptoms of Lermoyez syndrome in the right ear about 32 months ago. Audiologic data were obtained and imaging examinations were performed 0, 9, 15, 28, and 32 months after the onset of the Lermoyez syndrome. Pure tone threshold data obtained 5 months before the onset are also reported. The results show that the hearing thresholds, mainly at low frequencies, elevated rapidly during the first months shortly after the onset of the disease and slowly in later months. The glycerol test resulted in a remarkable hearing improvement at the beginning of the disease, but showed no detectable improvements as the disease advanced. Electrocochleogram revealed a -SP/AP value with click stimulus 0.65 at the 9th month and > 1.0 at the 28th month after the onset. Clinical manifestations of this patient fit well with a pathological endolymphatic hydrops.
