Tuberculous otitis media with osteomyelitis of the regional craniofacial bones

Abstract

Tuberculosis is an uncommon cause of chronic suppurative otitis media. Delay in diagnosis can lead to delayed treatment, resulting in significant complications. We describe a case of tuberculous otitis media with osteomyelitis of the craniofacial bones in a 44-year-old woman with chronic painless suppurative otorrhea, not responding to antibiotics, hearing loss, and facial palsy. Chest X-ray was normal. Computed tomography of the temporal bone showed the destruction of the left zygomatic bone, clivus, and petrous part of the temporal bone. Polymerase chain reaction was positive for Mycobacterium tuberculosis (MTB), and histopathological findings showed caseous necrotizing tissues. Sputum culture was negative for MTB. The patient was successfully treated with surgery and anti-tuberculosis drugs. The polymerase chain reaction is a sensitive, rapid diagnostic tool used to diagnose TB. Surgical approaches and operative biopsy should be considered when the cause of the chronic purulent discharge is still unknown.
