摘要
目的不同前庭刺激的整合能力受损是前庭性偏头痛（VM）的拟议机制。本研究旨在评估前庭性偏头痛患者的前庭-眼反射（VOR）和动态视敏度（DVA），并将评估结果与无前庭症状的偏头痛（MwoV）和持续性姿势-知觉性头晕（PPPD）进行比较，以确定两者是否存在鉴别差异，并寻找与焦虑水平的相关性。方法研究了 22 名 MwoV 患者、23 名 VM 患者、22 名 PPPD 患者和 23 名健康对照组（HC）。分别进行了无光动力背景（OB）和有光动力背景（OB）的视频头脉冲测试（vHIT）和功能性头脉冲测试（fHIT）。fHIT 测试考虑了正确识别光型的百分比（CA%）。所有患者组的 fHIT 和 fHIT/OB CA% 结果均低于健康对照组（p <0.005），其中 VM 患者的两项测试得分最低。PPPD 患者的 BAI 分数最高，焦虑水平与 fHIT 结果之间的相关性无法确定（p > 0.05）。这一鉴别特征与焦虑评分无关。难以解决视觉和前庭输入之间的冲突似乎是潜在的机制。
vHIT and fHIT in Patients With Migraine, Vestibular Migraine, and Persistent Postural-Perceptual Dizziness
Objective
Impairment in the integration of different vestibular stimuli is the proposed mechanisms in vestibular migraine (VM). In this study, it was aimed to assess the vestibulo-ocular reflex (VOR) and dynamic visual acuity (DVA) in patients with VM and to compare the results with migraine without vestibular symptoms (MwoV), and persistent postural-perceptual dizziness (PPPD) to find out if there are discriminative differences and search for a correlation with the levels of anxiety.
Methods
Twenty-two patients with MwoV, 23 patients with VM, 22 patients with PPPD, and 23 healthy controls (HC) were studied. Video head impulse test (vHIT) and functional head impulse test (fHIT) without and with an optokinetic background (OB) were performed. Percentage of correctly identified optotypes (CA%) was considered for the fHIT test. Beck anxiety inventory (BAI) was used to assess anxiety.
Results
Lateral canal vHIT gain of the patient groups were not different from the healthy controls (p > 0.05). fHIT and fHIT/OB CA% results of all patient groups were lower than the HC (p < 0.005), and VM patients had the lowest scores for both tests. BAI scores of the PPPD patients were the highest and a correlation between anxiety levels, and fHIT results could not be identified (p > 0.05).
Conclusion
Prominent CA% drop by the use of an OB was the main finding in patients with VM. This discriminative feature was not correlated with anxiety scores. Difficulty in resolving the conflict between visual and vestibular inputs seem to be the underlying mechanism.
期刊介绍：
The Laryngoscope has been the leading source of information on advances in the diagnosis and treatment of head and neck disorders since 1890. The Laryngoscope is the first choice among otolaryngologists for publication of their important findings and techniques. Each monthly issue of The Laryngoscope features peer-reviewed medical, clinical, and research contributions in general otolaryngology, allergy/rhinology, otology/neurotology, laryngology/bronchoesophagology, head and neck surgery, sleep medicine, pediatric otolaryngology, facial plastics and reconstructive surgery, oncology, and communicative disorders. Contributions include papers and posters presented at the Annual and Section Meetings of the Triological Society, as well as independent papers, "How I Do It", "Triological Best Practice" articles, and contemporary reviews. Theses authored by the Triological Society’s new Fellows as well as papers presented at meetings of the American Laryngological Association are published in The Laryngoscope.
