 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: The aim of this study is to evaluate the efficacy of prostaglandin I2 (PGI2) in the patients with chronic nonspecific vertigo using questionnaires of dizziness handicap inventory (DHI) and vertigo symptom scale (VSS). Materials and Methods: Forty two patients with chronic nonspecific vertigo from May to December 2010 were enrolled in this study. We administered Berast (synthetic PGI2, beraprost sodium) 2 tablets (0.04 mg) twice a day to patients. Before and after 2, 4 weeks the end of administration patients underwent DHI and VSS for evaluation of state of the vertigo. Results: Twenty four of 42 patients completed this clinical trial. Mean DHI scale score decreased significantly from 23.00 (±21.75) to 17.75 (±19.78) (p=0.004). All DHI subscales, physical, functional, and emotional factors, decreased after treatment of prostaglandin I2. VSS scale also showed significant decrease from 3.63 (±2.55) to 2.50 (±2.95) (p=0.044). Conclusion: Prostaglandin I2 may be one of the treatments to improve symptoms in the patient s with chronic nonspecific vertigo.
