Operations on the mastoid may be necessary when ear infection within the middle ear extends into the mastoid.The mastoid bone is the bony prominence that can be felt just behind the ear. It contains a number of air spaces, the largest of which is called the antrum. It connects with the air space in the middle ear. Therefore ear diseases in the middle ear can extend into mastoid bone.
This is done in Jubilee Christian Mission Hospital Trivandrum Kerala South India.
