本文通过对３０例突发性聋患者行纯音听力检查及前庭功能系列检查，比较突发性耳聋听力下降程度和类型与眩晕和前庭功能检查结果的关系、前庭损害类型和程度、以及听力预后与眩晕和前庭损害的关系。得出（１）具有前庭损害的患者９１％为中、重度聋，８２％为平坦型和斜坡型听力损害。半规管麻痹者听力损害全部为中、重度聋，图型为平坦或斜坡型。（２）冷热试验（ＣＰ）值６３％、低频谐波加速试验（ＳＨＡＴ）６６％、重心平衡仪试验（ＶＳＲＺ）３６％呈现异常，以ＳＨＡＴ较为敏感；（３）突聋听力预后与是否伴有眩晕、前庭损害以及损害程度有密切关系。
In this paper, 30 cases of sudden hearing loss in patients with pure hearing and vestibular function series of tests to compare the degree and type of sudden hearing loss of hearing loss and vertigo and vestibular function test results, the type and extent of vestibular damage, and hearing prognosis and Relationship between dizziness and vestibular damage. (1) 91% of patients with vestibular damage were moderate and severe deafness and 82% were flat and slope-type hearing impairment. Hemicronodular paralysis were all hearing loss in moderate and severe deafness, the pattern is flat or ramp type. (2) 63% of CP values, 66% of SHAT and 36% of VSRZ were abnormal, and SHAT was more sensitive. (3) The prognosis of sudden hearing loss and whether Accompanied by dizziness, vestibular damage and the degree of damage are closely related.
