继发性后半规管良性阵发性位置性眩晕的诊治

目的 探讨继发性良性阵发性位置性眩晕(BPPV)的诊断和治疗。方法研究继发性后半规管BPPV的内耳疾病6例病历资料，诊断依据为病史及Dix-Hallpike试验诱导出现的眼震结果。结果 6例内耳疾病(分别为突发性聋3例, 梅尼埃病2例, 前庭神经元炎1例)伴有后半规管良性阵发性位置性眩晕被确诊，通过Dix-Hallpike试验诱发出垂直扭转型眼震。结论 继发性BPPV临床较少见，常为后半规管受累，通过Dix-Hallpike试验和Epley手法复位可以确诊和治愈。

Diagnosis and treatment of secondary posterior semicircular canal benign paroxysmal positional vertigo

Objective To investigate the diagnosis and treatment of secondary benign paroxysmal positional vertigo (BPPV). Method We reported six cases of secondary posterior semicircular canal benign paroxysmal positional vertigo. The diagnosis was based on history and nystagmus induced by Dix-Hallpike test. Results Six cases of inner ear disease associated with the posterior semicircular canal benign paroxysmal positional vertigo was diagnosed by Dix-Hallpike test. There were three cases of sudden deafness, two cases of Meniere's disease and one case of vestibular neuronitis, respectively. Vertical torsional nystagmuses were induced in all the patients. Conclusions Secondary benign paroxysmal positional vertigo is rare in clinic, and posterior semicircular canal was involved mostly. It can be diagnosed and cured by the Dix-Hallpike test and Epley manipulative method.
