  • Otomycosis: It is the fungal infection of the ear and causes intense itching of the ear and cause fluid draining from ear. The discharge is usually white, brown, or black in color and can cause ear pain and discomfort.
  • Otitis externa hemorrhagic: it is characterized by the formation of granules of the eardrum and is seen in influenza epidemics. When granules rupture they cause intense itching and discharge from the ear.
  • Necrotizing otitis externa: it is an inflammatory condition caused in elderly diabetics or in immunosuppressive individuals. There are excruciating pain and ear discharge.

Middle Ear Infections:

  • Acute suppurative otitis media: infection of middle ear cleft i.e. Eustachian tube, mastoid air cells, ear bones. It is common in the low social class group and occurs after viral infections
  • Serous otitis media: it is formed due to serous fluid draining from the ear. It is more seen in children and school going kids.
  • Malignant otitis media: it is due to viral infections and causes rapid destruction of the whole of the eardrum and even mastoid cells. Healing is followed by adhesions.
  • IMPACTED WAX: wax is composed of secretion of sebaceous glands, hair cells, keratin debris, and dirt. It has a protective function and helps to keep dirt and bacteria away. Sometimes wax causes fluid draining from ear which is a relatively benign condition.
  • MISCELLANEOUS: Foreign body, maggots, traumatic rupture of the eardrum, and malignancy can also predispose to fluid draining from the ear.
