OPS-Code 5-203.x:
Other operations on middle and inner ear: Mastoidectomy: Other
You had surgery on the mastoid process behind the ear.
There is a small bony projection on the head behind the ear. It contains small cavities full of air. You can feel this bony projection behind the ear.The mastoid process is the name given to the bony projection on the skull directly behind the ear. The cavities inside it are connected to the middle ear. Diseases of the middle ear can spread to the mastoid process via this connection. The middle ear is an air-filled cavity. It transmits sound to the inner ear in the form of sound waves.
Your mastoid process was hollowed out. This is normally done by removing the walls between the individual cavities using a surgical burr drill. This procedure converts the many small cavities in the mastoid process into one large cavity.
