耳石復位法對良性陣發性位置性眩暈之療效
Treatment of Benign Paroxysmal Positional Vertigo with Canalith Repositioning Procedure
摘要
良性陣發性位置性眩暈的21位患者，在接受耳石後位法治療後，情況均有明顯改善。其中完全改善者佔90.5%，另有2例（9.5%）其位置性暈眩及眼振均消失，但仍有輕微頭昏現象（dizziness），可能是其他因素所引起。對於復發的病人（14.3%），給予再次的治療之後，亦有相當的效果（完全改善佔75%，改善佔25%）。因此，作者認為：給予耳石復位法清療，即簡單又方便，對病人沒有傷害性，實為治療良性陣發性位置性眩暈之價先選擇。

Clinically, patients with benign parox-ysmal positional vertigo (BPPV) may exhibit rotatory nystagmus and vertigo in the head down position with Hallpike maneuver. Schuknecht & Ruby proposed “heavy cupula” theory, Which held that the posterior semicircular chnal (PSC) is sensi-tive to gravity by dense particles attached to or impinging on its cupula of ampulla. An alternative explanation of pathophysio-logic mechanism of BPPV (Parnes & McClure) held that some BPPV cases result from free-moving densities in the endolymph of the PSC and produce rota-tory nystamus and vertigo by changing the position of patient’s head. Epley described the canalith repositioning procedure (CRP) and reported an excellent result in 30 patients who exhibited the classical nystag-mus of BPPV with Hallpike maneuver. In order to investigate the result of CRP, we selected 21 cases of BBPV with classical nystagmus and reported the result after CRP treatment. We found that the CRP for BPPV is cost-effective and provides timely resolution in a high percentage of cases, and the possibility of recurrence doss not significantly degrade its value. Therefore, CRP should be the initial proce-dure of choice for treatment of BPPV.
