WHY MONITOR PERILYMPHATIC PRESSURE IN MENIERES-DISEASE

A cohort of 39 patients with confirmed raised intracranial pressure wa s investigated. Of these patients, 24 (62%) complained of tinnitus and 11 (28%) suffered from paroxysmal rotary vertigo. Intracranial hypert ension can occur without the usual headache and visual symptoms. In su ch cases, the patient may be referred to the otolaryngological clinic and the condition may be mistaken for Meniere's disease or a labyrinth ine disorder. The Tympanic Membrane Displacement (TMD) technique now p rovides a non-invasive method of monitoring the intracranial and peril ymphatic pressures. This study provides recommendations for the use of TMD techniques in the otolaryngological clinic for screening, diagnos ing and monitoring treatment of patients presenting with raised perily mphatic pressure.
