What Are the Symptoms?
The most common symptom is that of recurrent ear drainage. The ear drainage sometimes has a foul odor. Drainage occurs because the cholesteatoma traps bacteria, which leads to recurrent ear infections. As the cholesteatoma enlarges, it can cause a full feeling or pressure in the ear, along with hearing loss. Dizziness or muscle weakness on one side of the face (the side of the infected ear) can also occur. Any, or all, of these symptoms are good reasons to seek prompt medical evaluation.
Is It Dangerous?
Ear cholesteatomas can be dangerous and should never be ignored. Cholesteatomas can cause destruction of surrounding bone through bone erosion. The cholesteatoma may destroy the delicate middle ear bones or, less commonly, the cholesteatoma may erode the surrounding structures such as the inner ear or brain. If untreated, deafness, brain abscess, meningitis, and rarely death can occur.
What Treatment Can be Provided?
Initial treatment may consist of a careful cleaning of the ear, antibiotics, and ear drops. Therapy aims to stop drainage in the ear by controlling the infection. After the infection is controlled, surgical removal is often recommended to prevent serious complications. A hearing test is performed, to help estimate if there is any damage to the middle ear bones or inner ear. A CT scan is often recommended to determine the size of the cholesteatoma. Surgery is performed under general anesthesia in most cases. The primary purpose of the surgery is to remove the cholesteatoma and achieve an infection-free, dry ear. Hearing preservation or restoration is the second goal of surgery. In most cases, patients are discharged on the same day of surgery.
