 Abstract
- Background and Objectives: It is necessary to establish the most efficient diagnostic and therapeutic method for benign paroxysmal positional vertigo (BPPV), which is appropriate for Korean healthcare system. We aimed to evaluate current state of Korean clinician’s diagnostic and therapeutic approaches for BPPV. Materials and Methods: A 16-item survey was emailed to the members of dizziness department of Otology Research Interest Group in the Korean Otologic Society (n=68). 43 were returned and analyzed. Results: All respondents (100%) used Dix-Hallpike test as a diagnostic tool for vertical canal-BPPV. Supine roll test was used for diagnosing lateral canal BPPV in nearly all the respondents (97.7%). Epley maneuver was chosen as otolith repositioning maneuver (ORM) for posterior canal BPPV in all respondents and barbecue rotation (BBQ) was used for treating lateral canal BPPV with geotropic nystagmus in 95.3% of respondents. Extreme variation was noted for therapeutic approach of lateral canal BPPV with ageotropic nystagmus BBQ, with 4 kinds of ORM and adjunctive measures to liberate otolith from cupula, while BBQ was again the most commonly used ORM (76.7%). Conclusion: The development of practical and efficient ORM for lateral canal BPPV with ageotropic nystagmus is necessary.

- Background and Objectives: Vestibular evoked myogenic potential (VEMP) is a relatively new diagnostic tool that is in the process of being investigated in patients with specific vestibular disorders. In this study, we examed the responses of VEMP in patients who complained of dizzines.
Materials and Method: Eighty-six patients with complaint of dizziness and ten normal volunteers are included in this study. Among these patients, forty-six patients were diagnosed as unilateral vestibulopathy (A), five patients were bilateral vestibulopathy (B), nine patients were sudden sensorineural hearing loss with vertigo (C), fifteen patients were benign paroxysmal positional vertigo (D) and eleven patients were Meniere's disease (E). We compared VEMP parameters in each group.
Results: In each group, abnormal response in VEMP was 33%(A), 0%(B), 11%(C), 12%(D) and 36%(E) respectively. and there was no absent VEMP formation, and there was no abscent VEMP formation.
Conclusion: VEMP is a promising method for diagnosing and following patients with many vestibular disorders.
