Surgical Procedures for Meniere's Disease

a. Surgical therapy for Meniere's disease is reserved for medical treatment failures and otherwise contraindicated.

b. Surgical procedures can be divided into main categories

- Destructive surgical procedures

- Nondestructive surgical procedures

a. Destructive surgical procedures: rationale to control vertigo Endolymphatic hydrops causes fluid pressure accumulation within the inner ear, which causes temporary malfunction and misfiring of the vestibular nerve. These abnormal signals cause vertigo.

Destruction of the inner ear and lor the vestibular nerve prevents these abnormal signals. The procedures performed are:

-Labyrinthectomy

- Intermittent low pressure pulse therapy (Meniett device therapy)

b. Conservative surgical procedure: are used in cases where vertigo is disabling but hearing is still useful and needs to be preserved. They are:

- Decompression of endolymphatic sac

- Endolymphatic shunt operation?

- Sacculotomy (Fick's operation? and Cody tack procedures)

- Vestibular neuronectomy

- Ultrasonic destruction of vestibular labyrinth to preserve cochlear function.
