Aural polyps
Otic polyp
An aural polyp is a growth in the outside (external) ear canal or middle ear. It may be attached to the eardrum (tympanic membrane), or it may grow from the middle ear space.
The ear consists of external, middle, and inner structures. The eardrum and the three tiny bones conduct sound from the eardrum to the cochlea.
Causes
Aural polyps may be caused by:
- Cholesteatoma
- Foreign object
- Inflammation
- Tumor
Symptoms
Bloody drainage from the ear is the most common symptom. Hearing loss can also occur.
Exams and Tests
An aural polyp is diagnosed through an exam of the ear canal and middle ear using an otoscope or microscope.
Treatment
Treatment depends on the underlying cause. Your health care provider may first recommend:
- Avoiding water in the ear
- Steroid medicines
- Antibiotic ear drops
If a cholesteatoma is the underlying problem or the condition fails to clear, then surgery may be needed.
When to Contact a Medical Professional
Contact your health care provider if you have severe pain, bleeding from an ear or a sharp decrease in hearing.
