Learning Objectives: Understanding the relationship between raised intracranial pressure and oto-neurological symptoms.

Raised intracranial pressure (ICP) is often managed by neurologists and neurosurgeons based on the severity of symptoms. Patients who have very high ICP (idiopathic intracranial hypertension - IIH) are dominated by headache, lethargy and visual disturbance. Closer questioning, however, reveals a multitude of ENT symptoms including pulsatile tinnitus, imbalance, facial pain and hearing disturbance.

This presentation discusses management of the otological manifestations of raised ICP and presents early evidence that raised ICP not only is a cause of meningoencephalocele and CSF otorrhoea but could also play a role in the development of superior semicircular canal dehiscence.
