Best ENT Hospital for Mastoidectomy: Unmatched Expertise and Superior Solutions with Dr. G V S Rao, Dr. G V K Chaitanya Rao and Dr. Shree Rao.

The mastoid bone, situated right behind the ear, is a non-rigid, sponge-like structure that can get infected due to an untreated infection in the middle ear.

Mastoidectomy, also called mastoid exploration, is complete removal of diseased mastoid air cells from the mastoid bone. A mastoidectomy can be done under general or local anaesthesia.

Conditions treated

There are 3 different types of mastoidectomy procedures, undertaken based on the type of conditions: –

  • Cortical mastoidectomy- for patients with safe type of middle ear disease, done to improve middle ear ventilation
  • Modified radical mastoidectomy (further divided into Inside out and outside in procedures) – for patients with unsafe type of middle ear disease/ cholesteatoma
  • Radical mastoidectomy – an extensive surgery reserved for conditions like ear cancers etc.

Why this surgery?

  • An untreated unsafe chronic middle ear infection that has spread to the mastoid bone, can later destroy one’s hearing, sense of balance and damage facial nerve to cause facial paralysis.
  • As the ear is situated very close to the brain, it can also cause brain infections.


It is essential to carry out a mastoid exploration to remove all diseased parts of the bone to remove or reduce the risk of complications like, loss of hearing, affecting sense of balance, facial paralysis and brain infections.

  • Mastoidectomy, like any other surgery, carries some risks. Following are the risks that one should know prior to giving consent to this treatment: –

    • Taste disturbance: The taste nerve runs close to the eardrum and may sustain some damage to cause abnormal taste on one side of the tongue. While this taste disturbance is mostly a temporary phenomenon, it may be permanent in some cases.
    • Dizziness: Dizziness for a few hours after the surgery is normal. In some cases, it may last longer.
    • Hearing loss: Very rarely, if the patient’s inner ear is damaged, severe deafness can occur.
    • Tinnitus: If the hearing loss worsens, the patient may suffer from tinnitus or noises in the ear.
    • Facial Paralysis: As the facial nerve controlling face muscles runs through the ear, there is a slight chance of a partial or total facial paralysis affecting movements such eye closure, smiling and raising the forehead. This facial paralysis can occur immediately after the surgery or after a while. Recovery can be partial or total.
    • Allergic reaction to ear dressings: Occasionally the ear may show allergy to the dressings in the ear canal leading to a red, swollen and inflamed pinna (outer ear). Consult the surgeon for dressing removal and settling down of the allergic reaction.
    • Risks of a general anaesthetic must also be kept in mind.Best ENT Hospital for Mastoidectomy: Unmatched Expertise and Superior Solutions with Dr. G V S Rao, Dr. G V K Chaitanya Rao and Dr. Shree Rao.
