[Sudden sensorineural hearing loss and jugular bulb diverticulum].
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.
