Causes, incidence, and risk factors
Sebaceous cystsare the most common type of cystsseen in the ear. They are bulging, sac-like collections of dead skin cells and oils produced by oil glands in the skin.
They commonly occur:
- Behind the ear
- In the ear canal
- In the earlobe
- On the scalp
The exact cause is unknown, but cysts may occur when oils are produced in a skin gland faster than they can be released from the gland.
Benignbony tumors of the ear canal (exostoses and osteomas) may be caused by excess growth of bone. Repeated exposure to cold water may increase the risk of benign tumors of the ear canal.
