Abstract

Objectives: This study aimed to determine if the presence of corrective saccades during video head impulse test (vHIT) stimulation of the bilateral posterior semicircular canals (PSCs) correlated with other vestibular test results, demographics, symptoms, or diagnoses.

Design: This study was a retrospective chart review where 1006 subjects' vHIT records were screened with 17 subjects meeting inclusion criteria for isolated bilateral PSC saccades.

Results: Of the 1006 patients undergoing vHIT testing, only 1.7% had isolated bilateral PSC saccades. The median age of subjects was 73 years, with a range of 61 to 85 years. Statistical significance was identified between groups with abnormal PSC vHIT gain and abnormal ocular vestibular evoked myogenic potential results as well as those with 1 to 2 diagnoses.

Conclusions: Our study confirms the rarity of isolated bilateral PSC vHIT saccades and as well as association with central vestibulopathy. Correlations with other vestibular test results, demographics, symptoms, or diagnoses may be strengthened with future large-scale studies. Further understanding of the clinical utility of isolated bilateral PSC vHIT saccades is needed. Patients with bilateral PSC vHIT abnormalities may benefit from a comprehensive neurological evaluation and consultation.

视频头脉冲试验中双侧后管刺激引起的孤立性矫正性扫视：中枢性前庭病变的标志？

目的：本研究旨在确定在视频头部脉冲试验（vHIT）刺激双侧后半规管（PSCs）时出现矫正性扫视是否与其他前庭测试结果、人口统计学、症状或诊断相关。设计：本研究采用回顾性图表分析，筛选1006名受试者的vHIT记录，其中17名受试者符合孤立性双侧PSC扫视的纳入标准。结果：在1006例接受vHIT检测的患者中，只有1.7%的患者有孤立的双侧PSC扫视。受试者年龄中位数为73岁，年龄范围为61 ~ 85岁。PSC vHIT增益异常组、眼前庭诱发肌电位异常组及1 ~ 2例诊断组间差异有统计学意义。结论：我们的研究证实了孤立性双侧PSC vHIT扫视的罕见性以及与中枢性前庭病变的相关性。与其他前庭测试结果、人口统计学、症状或诊断的相关性可能会在未来的大规模研究中得到加强。需要进一步了解孤立的双侧PSC vHIT扫视的临床应用。双侧PSC vHIT异常的患者可能受益于全面的神经学评估和咨询。

期刊介绍： From the basic science of hearing and balance disorders to auditory electrophysiology to amplification and the psychological factors of hearing loss, Ear and Hearing covers all aspects of auditory and vestibular disorders. This multidisciplinary journal consolidates the various factors that contribute to identification, remediation, and audiologic and vestibular rehabilitation. It is the one journal that serves the diverse interest of all members of this professional community -- otologists, audiologists, educators, and to those involved in the design, manufacture, and distribution of amplification systems. The original articles published in the journal focus on assessment, diagnosis, and management of auditory and vestibular disorders.
