Can an ear that has been discharging pus for twenty years still be cured?

Whether a 20-year history of ear discharge can be cured depends on the underlying cause, such as external auditory canal eczema, chronic suppurative otitis media, or tympanic membrane perforation.

1. External Auditory Canal Eczema

Persistent untreated external auditory canal eczema can lead to long-term ear discharge. After cleaning with saline solution, following medical advice to use medications such as loratadine, tacrolimus ointment, or hydrocortisone butyrate cream usually leads to improvement.

2. Chronic Suppurative Otitis Media

This condition may develop when otitis media is not treated promptly or recurs frequently. Under a doctor's guidance, anti-inflammatory treatment using ofloxacin ear drops, levofloxacin capsules, or chloramphenicol ear drops generally achieves therapeutic goals.

3. Tympanic Membrane Perforation

Perforation of the tympanic membrane caused by viral or bacterial infections inside the ear can also result in discharge. Following medical instructions, treatment with penicillin V potassium tablets, moxifloxacin hydrochloride tablets, or undergoing tympanoplasty typically results in successful recovery.

In addition, cholesteatoma-type otitis media may also cause prolonged ear discharge; however,积极 treatment under medical supervision can yield favorable outcomes.
