不同类型位置性眩晕的诊断及耳石复位治疗

Diagnosis and CRP-therapy for the different types of benign paroxysmal positional vertigo

目的探讨不同类型位置性眩晕(benign paroxysmal positional vertigo,BPPV)的诊断方法和半规管耳石复位法对BPPV的治疗效果及存在的问题。方法从2005年1月～2007年12月对疑似BPPV患者行变位性眼震试验,并对确诊为BPPV的96例患者行耳石复位治疗。结果所有BPPV患者经1～2次耳石复位治疗,症状完全消失者84例(87.5%);眩晕消失但遗有与体位变换无关的头昏、头重脚轻感者12例(12.5%),其中10例头部症状于1周内消失,2例于2周内消失。结论不同类型BPPV在诊断方式上存在差异,耳石复位治疗BPPV安全有效,应作为首选。

OBJECTIVE To discuss the diagnosis of the different types of benign paroxysmal positional vertigo （BPPV） and its treatmeat by canalith repositioning procedure （CRP） . METHODS 96 patients with BPPV were diagnosed by positioning nystagmus and treated by CRP from January 2005 to December 2007. RESULTS After one or two treatment sessions of CRP, the symptoms disappeared completely in 84 of 96 patients （87.5%） . 12 patients had no the vertigo symptoms but showed dizziness or lightheadedness which has no relation with body position-change. These symptoms disappeared in 10 patients in one week and 2 patients in two week. CONCLUSION There are many differences among the diagnostic methods for the different types of BPPV.The CRP therapy is safe and effective for BPPV and should be applied for all patients when the diagnosis is defined.
