A 40-year-old male with unsafe CSOM has a cholesteatoma that has eroded the tegmen and caused otitic meningitis. After IV antibiotics and neurosurgical consultation, the appropriate ENT surgical timing is:

• A Emergency mastoidectomy within 6 hours to drain the focus
• B Mastoidectomy contraindicated in presence of meningitis; medical management only
• C Mastoidectomy after lumbar puncture and 48 hours of antibiotics
• D Mastoidectomy deferred until meningitis is fully treated and patient is stable (typically 2–4 weeks) ✓

Explanation

In otitic meningitis secondary to cholesteatoma, the standard approach is to first control the acute meningitis with IV antibiotics and stabilize the patient neurologically (typically 2–4 weeks). Mastoidectomy is then performed electively to eradicate the cholesteatoma and prevent recurrence. Emergency surgery on an acutely inflamed meningitic brain carries high risks of hemorrhage and worsening edema. However, if there is a concomitant extradural or subdural abscess requiring drainage, combined neurosurgical-ENT intervention may be needed earlier.
