BACKGROUND
Few studies focused on the prognosis of unilateral idiopathic sudden sensorineural hearing loss (UISSNHL) with vertigo.
OBJECTIVES
To describe how the semicircular canal (SCC) function tests may prove helpful in the diagnosis of UISSNHL with vertigo.
MATERIAL AND METHODS
59 UISSNHL patients underwent audiometry, caloric test and video head impulse test (vHIT). The correlation between hearing loss and SCC dysfunction was analyzed.
RESULTS
The results showed significant differences of hearing loss grades (p = 0.004) and hearing loss configurations (p = 0.009) between UISSNHL patients with and without vertigo. In vHIT, the gains of horizontal canal (HC) and posterior canal (PC) were more frequently impaired compared with that of anterior canal (AC). The abnormal rate of caloric test was the highest, followed by the abnormal rates of HC and PC gain. A significant difference of abnormal rate of HC gain was only found between the mild and moderate UISSNHL patients with and without vertigo (p = 0.029).
CONCLUSION
Abnormal SCC function happens frequently in patients with profound hearing loss. Ipsilesional abnormal vHIT (especially the HC gain) in the presence of abnormal caloric test is a pattern of findings observed in mild and moderate UISSNHL patients with vertigo.
背景
很少有研究关注伴有眩晕的单侧特发性突发性聋（UISSNHL）的预后。
目的
描述半规管（SCC）功能测试在伴有眩晕的 UISSNHL 的诊断中可能如何提供帮助。
材料和方法
59 例 UISSNHL 患者接受了听力测试、冷热试验和视频头脉冲试验（vHIT）。分析了听力损失与 SCC 功能障碍之间的相关性。
结果
结果显示，伴有眩晕和不伴有眩晕的 UISSNHL 患者的听力损失程度（p=0.004）和听力损失类型（p=0.009）存在显著差异。在 vHIT 中，与前半规管（AC）相比，水平半规管（HC）和后半规管（PC）的增益更常受损。冷热试验的异常率最高，其次是 HC 和 PC 增益的异常率。仅在伴有眩晕的轻度和中度 UISSNHL 患者中，HC 增益的异常率存在显著差异（p=0.029）。
结论
严重听力损失患者 SCC 功能异常较为常见。伴有异常冷热试验的同侧异常 vHIT（尤其是 HC 增益）是伴有眩晕的轻度和中度 UISSNHL 患者的一种观察结果模式。
