摘　　要：良性发作性位置性眩晕(BPPV)是最常见的导致眩晕的疾病,其病理生理学基础为耳石的脱落,因此又被称为"耳石症"。虽然大多数BPPV的病因为原发性,传统上认为是一种良性、自限性的前庭周围性疾病,然而理论上任何能够导致耳石脱落的因素都可以导致BPPV的发生。评价BPPV的不同病因将对临床诊治有重要意义。本文就BPPV的相关病因进行了综述。Benign paroxysmal positional vertigo（BPPV） is by far the most common type of vertigo. The fundamental pathophysiological process in BPPV involves dislodged otoconia from the macula of the utricular otolith that enter the semicircular canals. Most BPPV are regarded as idiopathic and benign, self- limited vestibular diseases. However, theoretical, any factors that can facilitate the otolith fall off might lead to BPPV. It is important to understand the different etiologies of BPPV for the clinic diagnosis and treatment. This article reviewed the related etiological factors of BPPV.
