The relationship between high placed jugular bulb (diverticulum) and inner ear disorder is not well known. Three of 19 patients with sudden sensorineural hearing loss (SSHL) treated in 1995 had right side jugular bulb diverticulum revealed by CT scan and MRA. One of the 3 SSHL cases complicated with delayed endolymphatic hydrops. The exact mechanism of causation of inner ear symptom is not clear, but may partly be due to pressure effects with the jugular fossa encroaching on inner ear structure such as the cochlear aqueduct and vestibular aqueduct, and due to turbular flow in the diverticulum striking the inner ear. It is needed to further study the influence of the diverticulum on the inner ear.
高位颈静脉球（憩室）与内耳疾病之间的关系尚不清楚。1995年接受治疗的19例突发性感音神经性听力损失（SSHL）患者中，有3例经CT扫描和MRA显示右侧颈静脉球憩室。3例SSHL病例中有1例并发迟发性内淋巴积水。内耳症状的确切病因尚不清楚，但部分可能是由于颈静脉窝侵犯内耳结构（如蜗水管和前庭水管）产生的压力效应，以及憩室内的紊乱血流冲击内耳所致。需要进一步研究憩室对内耳的影响。
