Discharge or Drainage from the Ear – Causes, Diagnosis and Treatment

Common Causes of Discharge or Drainage from the Ear

1. Otitis Media: Middle ear infections can lead to the buildup of fluid and pus, resulting in ear discharge, often accompanied by ear pain.
2. Swimmer’s Ear (Otitis Externa): Infections of the ear canal caused by water exposure or skin conditions can result in discharge, itching, and discomfort.
3. Earwax Buildup: Excessive earwax can become impacted and lead to drainage from the ear.
4. Ruptured Eardrum: A tear or hole in the eardrum, often due to infections or trauma, can cause ear discharge and hearing loss.
5. Cholesteatoma: An abnormal skin growth in the middle ear can produce foul-smelling ear discharge and may lead to complications if not treated.
6. Ear Tubes: Tubes inserted into the eardrums to treat recurrent ear infections can sometimes cause temporary discharge as they facilitate fluid drainage.
7. Foreign Body: Insertion of foreign objects into the ear can damage the ear canal and cause discharge.
8. Allergies: Allergic reactions or skin conditions affecting the ear can result in itching and discharge.
9. Mastoiditis: Infection of the mastoid bone, located behind the ear, can cause ear discharge along with pain and swelling.
10. Tumor or Growth: Benign or malignant growths in the ear can produce ear discharge and may require medical intervention.
