Intracranial complications after surgical removal of nasal polyps.

Acute otitis media can be caused by viruses (nonsuppurative inflammation) and bacteria (suppurative inflammation). The suppurative inflammation is a risk factor for endocranial complications, including subdural empyema burdened with a high mortality. The authors present a clinical case of a 67-year-old man treated by surgery for a subdural empyema in the course of the acute suppurative otitis media.
