• A Mastoidectomy is a procedure performed to remove the mastoid air cells. This can be done as part of treatment for mastoiditis, chronic suppurative otitis media or Cholesteatoma . In addition, it is sometimes performed as part of other procedures (cochlear implant) or for access to the middle ear. There are classically 5 different types of Mastoidectomy:
•  Simple mastoidectomy: the surgeon opens the mastoid bone, removes the infected air cells, and drains the middle ear
• Radical mastoidectomy: the surgeon may remove the eardrum and middle ear structures. Sometimes a skin graft is placed in the middle ear.

A mastoidectomy is usually performed under general anaesthesia. This ensures the patient is asleep and unable to feel pain


Surgical steps in short
• use a microscope and a small drill to open the mastoid bone
• use suction irrigation to keep the surgical area free of bone dust
• remove the infected air cells
• stitch up the operative site
• Graft a ear drum if required
• Repair ossicles if necessary
• Mastoid dressing  given

Final outcome-The outcome of a mastoidectomy is a clean, healthy ear without infection. However, both a modified radical and a radical mastoidectomy usually result in less than normal hearing.
