CSOM With Chronic Wet Ear in Adults: Second-Line Protocol After First-Line Fluoroquinolone Therapy Failed
This protocol is for adults with chronic suppurative otitis media (CSOM) without suspected cholesteatoma who present with a persistently discharging (wet) ear and whose otorrhea has not resolved despite completing a full first-line treatment course.
Clinical Scenario
CSOM without suspected cholesteatoma is managed differently depending on whether the ear is typically dry or chronically wet. With a wet ear, the infection is likely to be polymicrobial, which shapes the approach to treatment selection.
Why This Protocol Applies — First-Line Failure
First-line therapy did not achieve the goal. The initial approach — aural toilet with removal of debris from the ear canal, combined with topical and oral fluoroquinolones — is considered to have failed when otorrhea continues after three weeks of therapy. This second-line protocol is the structured next step when that threshold has been reached.
Second-Line Approach
Treatment Goal
Primary objective
Resolution of otorrhea. Treatment is considered to have failed if discharge persists after three weeks of therapy.
