Abstract

BACKGROUND AND OBJECTIVES: Recurrent vestibulopathy is defined a disease characterized by more than a single episode of vertigo of duration characteristic of endolymphatic hydrops but without auditory or clinical neurological symptoms or signs. To investigate the clinical characteristics and the efficacy of combination therapy, we analyzed the clinical records of the patients diagnosed as recurrent vestibulopathy. MATERIALS AND METHOD: Clinical records of sixty four patients diagnosed as recurrent vestibulopathy were retrospectively reviewed. The data on age, sex distribution, natural history, family history of recurrent vestibulopathy, concurrent headache, caloric response was analyzed. The efficacy of combination therapy for vertigo control in the patients with a minimum 24-month follow-up was also evaluated.
RESULTS
Mean onset age of recurrent vestibulopathy was 43 years and there was a female preponderance. Concurrent headache and elevated SP/AP ratio in electrocochleogram was frequently observed in these patients. After the combination medical therapy, patients with severe recurrent vestibulopathy showed significant decrease in the number of vertigo spells with 37.5% of complete control of vertigo.
CONCLUSION
As a distinctive clinical disorder with unknown cause, recurrent vestibulopathy should be always considered to the patients complaining recurrent episodic vertigo. Combination therapy individualized to the symptoms and signs of the patients with recurrent vestibulopathy might be effective in reducing the frequency of vertigo attacks. Further case-control studies with large population should be necessary.
