What happens during a mastoidectomy?
Diagnosis
A mastoidectomy can be performed for either a cholesteatoma or a severe mastoid infection. Its symptoms can often be confused with other ear infections and problems, thus, your ENT doctor needs to perform a thorough diagnosis before drafting a treatment plan.
To confirm the diagnosis, you may need several diagnostic tests like blood tests, along with imaging scans like MRI, CT scan, and X-rays of your head and ear area. The scan will help determine the severity of mastoid degeneration. In case there is a chance that the infection has spread to the skull, you may also need a lumbar puncture or spinal tap.
Treatment
Depending on the severity of your condition, your surgical treatment may vary a little. A simple mastoidectomy involves only the removal of the diseased part of the bone and leaves the ear canal intact. However, if you need extensive surgery, then your surgeon may need to combine your ear canal and mastoid bone by widening the ear canal to preserve hearing function. This type of surgery is known as a radical or modified mastoidectomy.
The surgery is usually performed under local anesthesia, and you would be able to go home on the same day as the surgery. The surgical incision is created behind the ear to minimize the scar appearance, and once the infected areas of bone are removed, the incision is closed with sutures and dressed appropriately. The complete procedure takes about 2-3 hours to complete.
