반고리관결석 정복술 후 최종 두위에서 기록된 안진 반응에 의한 운동치료효과 예측

Background and Objective: Benign paroxysmal positional vertigo (BPPV) is a common etiology of vertigo. Variable exercise maneuvers and treatment results of BPPV have been reported. We aim to evaluate applicability of nystagmus response in the final head position after the modified Epley maneuver as the predictor of the treatment efficacy. Materials and Methods: The nystagmus response was recorded in the final head position after the modified Epley maneuver and compared with the subsequent response obtained by Dix-Hallpike test after 1 week. The study included 12 patients with a diagnosis of BPPV based on the history and Dix-Hallpike test. Results: After the first Epley maneuver, 9 patients showed negative nystagmus response and 3 patients positive while sitting in the final head position. As compared with the results of Dix-Hallpike test after 1 week, only 2 of the 9 patients, who had no nystagmus in the final head position after the first Epley maneuver, and 2 of the 3 patients, who had nystagmus, showed positive nystagmus response. The overall results of the Epley maneuver showed that the patients who had no nystagmus in the final head position tended to be better than those who had nystagmus. Conclusion: The nystagmus response in the final head position after the modified Epley maneuver could be the predictor of the treatment efficacy. (J Clinical Otolaryngol 2001;12:41-46)
