12.Trans Tympanic Electrocochleography

This test measures the distortion of inner ear membranes (linings) caused by the presence of excess inner ear fluid. It is useful in the diagnosis of Meniere’s Disease and related disorders.

The test is performed by an expert otolaryngologist and involves placing a thin wire (electrode) through a small piercing that is made in a safe place on the ear drum. The ear drum is anaesthetised beforehand. During the test, noises (clicks or tones of specific frequencies) are presented through headphones.

After the test, patients are advised to keep the ear dry for one week.
