耳石粒子復位法:一種治療良好性陣發性位置性眩暈之有效方法

Particle repositioning Maneuver: An Effective Treatment for Benign Paroxysmal Positional Vertigo

摘要


背景:對於良性發性位置性眩暈(benign paroxysmal positional vertigo,簡稱BPPV)的治療,過去不論使用藥物治療或物理治療,效果均不佳。自1979年Epley提出”耳石復位法” (canalith repositioning procedure,簡稱CRP)來治療病人,其成功率可達80%以上,且因方法簡易可靠而廣為採用。 方法:本科自1995年1月至1996年5月,共72人被診斷為良性陣發性位置性眩暈而接受修飾過的”耳石粒子復位法”(particle repositioning maneuver,簡稱PRM)治療。其中65人完成追蹤,男性21人,女性44人,平均年齡49.1歲,平均追蹤11.1個月。 結果:症狀完全消失共55人(其中37人只做一次PRM,其餘做2~5次),占84.6%;症狀改善而仍微暈者共7人,占10.8%;症狀持續而沒有改變共3人,占4.6%。 結論:臨床經驗顯示,耳石粒子復位法是一簡單、可靠而有效的法療方式,可做為治療良性陣發性位置性眩暈之第一線選擇。

Background: Benign paroxysmal positional vertigo (BPPV) is a disorder of the inner ear, usually of the posterior semicircular canal (PSC). Traditional treatment, no matter by medicines or by physical therapy such as vestibular habituation, has proved to be of little effect. The recent demonstration of free-floating particles (canaliths) in the endolymph of the PSC in patients with BPPV has renewed the interest and treatment of this disease. The particle repositioning maneuver (PRM), an effective method modified from Epley’s canalith repositioning procedure (CRP) relocates the canaliths from the PSC back into the utricle, relieving the patients of annoying, often long standing vertigo. Methods: A prospective study of 65 consecutive patients diagnosed as BPPV by Dix and Hallpike’s description from January 1995 to May 1996. All of the patients (mean 49.1 years old) received the PRM with follow-up period ranged from 6 to 20 months (mean 11.1 months). Results: the PRM relieved symptoms without recurrence in 55 (84.6) patients. A partial response was noted in 7 (10.8%) patients, and there was no imprvement in 3 (4.6%) patients. Conclusions: Particle repositioning maneuver is a simple, safe and effective treatment for most patients with BPPV and recommended it as the first-line treatment modality for BPPV.
