目的：分析确诊型前庭性偏头痛（dVM）的临床特征及相关检测结果，优化dVM诊断标准。方法：按 照Bárány学会诊断标准，纳入就诊于我院的dVM患者42例，对其临床资料进行回顾性分析。结果：本组患 者年龄为24～68岁，平均（48.9±11.9）岁；男女比例为1:4.3。38.1%（16例）为头运动诱发眩晕，61.9%（26例） 为自发性眩晕；64.3%（27例）dVM患者发作持续时间＞1 h；73.8%（31例）为无先兆偏头痛，52.4%（22例）的 患者偏头痛起病早于前庭症状；81.0%（34例）患者有畏光、畏声的表现；50.0%（21例）有晕动症，26.2%（11 例）患者伴听力受损，温度试验后33.3%（14例）患者伴单侧半规管功能减低，同时有40.5%的患者伴温度试 验不耐受。30.9%（13例）的dVM患者中枢眼动异常，38.1%（16例）免疫相关指标异常患者，其中血清甲状 腺抗体阳性10例（62.5%）。结论：dVM以女性多见，眩晕多呈自发发作，症状持续时间多＞1 h，偏头痛起病 多早于前庭症状，发作时多伴畏光畏声；晕车史及双温试验不耐受亦不少见。

o analyze the clinical manifestations and related test results of definite vestibular migraine (dVM), optimizing it's diagnostic criteria. Methods: According to the diagnostic criteria of the Bárány Society, 42 dVM patients admitted to our hospital were included. Their clinical data were retrospectively analyzed. Results: The age ranged from 24 to 68 years, with an average age of (48.9±11.9) years. The male-to-female ratio was 1:4.3. 38.1% (16 cases) were vertigo induced by head movements and 61.9% (26 cases) were spontaneous vertigo. 64.3% (27 cases) had a duration of seizures longer than 1 hour. 73.8% (31 cases) were non-aura migraines and 54.2% (22 cases) of patients had migraine onset earlier than vestibular symptoms. 81.0% (34 cases) of patients had photophobia and photophobia. 50.0% (21 cases) had motion sickness and 26.2% (11 cases) had hearing impairment. 33.3% (14 cases) had unilateral semicircular canal impairment after temperature test and 40.5% showed temperature test intolerance. 30.9% (13 cases) of patients with dVM had abnormal central eye movements. 38.1% (16 cases) had abnormal immune-related indicators including 10 cases (62.5% ) had serum thyroid antibodies. Conclusion: dVM is more common in women. Vertigo usually occurs spontaneously and symptom duration is longer than 1 h in most instances. Migraine onset occurs earlier than vestibular symptoms, which is often accompanied by photophobia. A history of motion sickness and intolerance in double temperature tests are not rare.
