Definition    Return to top

Benign ear cysts are noncancerous lumps or growths in the ear.

Causes    Return to top

Sebaceous cysts are the most common type of cysts seen in the ear. They are bulging, sac-like collections of dead skin cells and oils produced by oil glands in the skin.

Treatment    Return to top

If the cyst or tumor is not painful and does not interfere with hearing, treatment is not necessary.

If a cyst becomes painful, it may be infected. Treatment may include antibiotics or removal of the cyst.

Benign bony tumors may progressively increase in size. If a benign tumor is painful or interferes with hearing, surgical removal of the tumor may be necessary.

Benign ear cysts and tumors are usually slow-growing and may disappear on their own.
