To understand the videonystagmography (VNG) findings in various balance disorders in 67 patients who presented to the outpatient department of an otorhinolaryngology clinic.
This cross-sectional study was conducted in the outpatient department of the otorhinolaryngology clinic of a tertiary care center. A total of 67 patients between the age group of 18 and 70 years with balance disorders were included in the study. VNG findings in different balance disorders were observed and analyzed.
A total of 67 patients were enrolled in the study. Findings like caloric inversion and optokinetic nystagmus do not always indicate a central balance disorder due to technical errors and other limitations during the test. However, abnormal saccades seem to be a more relevant finding in central disorders. Rare variants of benign paroxysmal positional vertigo (BPPV) like multiple canal BPPV were also diagnosed using VNG.
VNG has come out as a very useful test in our study aiding in 75% of diagnoses. The overall benefits of VNG in balance disorders are immense and necessitate their inclusion in every vertigo clinic.
了解67例就诊于耳鼻喉科门诊的各种平衡障碍患者的视频眼震图（VNG）检查结果。
本横断面研究在一家三级医疗中心的耳鼻喉科门诊进行。研究共纳入67例年龄在18至70岁之间患有平衡障碍的患者。观察并分析不同平衡障碍的VNG检查结果。
本研究共纳入67例患者。由于测试过程中的技术误差和其他限制，冷热试验倒置和视动性眼震等检查结果并不总是表明存在中枢性平衡障碍。然而，异常扫视似乎是中枢性疾病中更相关的检查结果。还通过VNG诊断出了罕见的良性阵发性位置性眩晕（BPPV）变异型，如多半规管BPPV。
在我们的研究中，VNG已成为一项非常有用的检查，有助于75%的诊断。VNG在平衡障碍方面的总体益处巨大，因此每个眩晕门诊都有必要开展此项检查。
