- Background and Objectives: The purpose of this study were to evaluate the therapeutic efficacy of canalith repositioning maneuver (CRP) according to accompanying mastoid percussion and to investigate the prognostic factors that may affect successful repositioning maneuver and the recurrence of benign paroxysmal positional vertigo.
Materials and Method: A total of 70 patients with canalith type BPPV visiting the dizziness clinic of Kangnam St. Mary's Hospital were included in this study. Variables identified for statistical analysis were patient's age, sex,maneuver method, number of involved canal, number of CRP and dizziness handicap inventory.
Result: Overall success rate of CRP was 90%. The mean number of maneuver was 1.6 and the recurrence rate was 25.7% during the follow up period. Success rate of CRP (94.9%) was higher than maneuver without mastoid percussion (83.9%) though it was not statistically significant. Successful CRP group showed the significant less number of maneuvers at initial treatment session and less number of involved canal than failed CRP group at the time of one week-follow up visit. Patients with recurrence of BPPV had the more number of CRP during the period of previous BPPV.
Conclusion: Therapeutic efficacy of CRP with mastoid percussion was higher than CRP without mastoid percussion though it was not statistically significant. Suggesting prognostic factors for effective CRP and recurrence were number of CRP and number of involved canal.

- 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.
