The injections are performed with the patient lying down and using the office microscope. The ear is first cleaned of wax. A small area of the eardrum is numbed with a drop of medication. A small needle and syringe are then used and the needle is passed through the eardrum at the site that is numbed so that the tip is in the ear, near the round window. This is a membrane where drugs are absorbed in to the cochlea. The fluid is injected in to the middle ear and the patient stays lying down for 20-30 minutes during which he does not swallow or sniff. The drug sits against the round window and is absorbed in to the inner ear. The patient then sits up slowly and leaves the office. Patients should not drive for a few hours after this procedure. Water is kept out of the ear until it is confirmed that the tiny hole has healed.
Managing an acute attack involves preparation. This includes consulting with a physician about any appropriate drugs that can be taken when an acute attack occurs, and deciding ahead of time when it is appropriate to go to a hospital. During an attack, it is helpful to lie down in a safe place with a firm surface, and avoid any head movement. Sometimes keeping the eyes open and fixed on a stationary object about 18 inches away is helpful. In order to control dehydration, a doctor should be called if fluid intake is not possible over time due to persistent vomiting.
