The purpose of this study is to review etiologies and identify the time-course of vertigo presenting in an ear, nose, and throat clinic, and serve as a reference guide for other clinics. The study includes retrospective chart review in a tertiary care, university hospital. The patient data with reported ICD-10 codes as causes of vertigo between April 2005 and December 2007 were extracted from the database. At each visit, the main diagnosis as to etiology, characteristics of the vertigo, its time-course, and patient demographic data were recorded. Of 547 cases, 17 diagnoses were made in 73.9%. Diagnostic categories included peripheral vertigo 72.9%, central vertigo 0.8%, psychogenic cause 0.2%, and unknown 26.1%. Common causes of vertigo were benign paroxysmal positional vertigo (BPPV) 52.5%, Meniere's disease 14.6%, and sudden idiopathic hearing loss 2.9%. Less common diagnoses were benign paroxysmal vertigo of childhood 0.7%, labyrinthitis 0.7%, and vestibular schwannoma 0.3%. Rare conditions were delayed endolymphatic hydrops, Ramsey Hunt syndrome, otosyphilis, vestibular neuritis, temporal bone fracture, post-concussion syndrome, cerebellar infarction, epilepsy, cervical vertigo, Streptococcus suis meningitis, and psychogenic vertigo. Ninety-nine cases who reported remission of vertigo during the study period had median onset of the remission at 4 weeks. In the ear, nose, and throat clinic at Chiang Mai University, a tertiary university hospital, peripheral vestibular disorders were the main etiology of vertigo. The three most common causes were BPPV, Meniere's disease, and sudden idiopathic hearing loss. Half of the cases who returned for follow up had remitted symptoms within 4 weeks.
本研究旨在回顾病因，并确定耳鼻喉科就诊时眩晕的时间进程，为其他科室提供参考指南。该研究包括在三级保健、大学医院进行的回顾性图表审查。从数据库中提取了 2005 年 4 月至 2007 年 12 月期间以 ICD-10 编码报告的眩晕病因的患者数据。在每次就诊时，均记录了病因、眩晕特征、时间进程以及患者人口统计学数据的主要诊断。在 547 例患者中，17 例（73.9%）做出了诊断。诊断类别包括周围性眩晕 72.9%、中枢性眩晕 0.8%、心因性眩晕 0.2%和未知病因 26.1%。常见的眩晕病因包括良性阵发性位置性眩晕（BPPV）52.5%、梅尼埃病 14.6%和突发性特发性听力损失 2.9%。较少见的诊断包括儿童良性阵发性眩晕 0.7%、迷路炎 0.7%和前庭神经鞘瘤 0.3%。罕见疾病包括迟发性内淋巴积水、Ramsey Hunt 综合征、耳梅毒、前庭神经炎、颞骨骨折、脑震荡后综合征、小脑梗死、癫痫、颈性眩晕、猪链球菌脑膜炎和心因性眩晕。在研究期间报告眩晕缓解的 99 例患者中，缓解的中位数发病时间为 4 周。在清迈大学的耳鼻喉科，三级大学医院，周围性前庭障碍是眩晕的主要病因。三种最常见的病因是 BPPV、梅尼埃病和突发性特发性听力损失。一半返回复诊的患者在 4 周内症状缓解。
