| pubmed-article:1670610 | pubmed:abstractText | From 1979 to 1988, 17 patients presented to Duke University Medical Center for treatment of subdural empyema. Empyemas were caused by sinusitis in 53% of the patients and by otitis media in 12%. None of those with otologic causes required mastoid drainage, while all patients with sinus infections required sinus drainage. External frontoethmoidectomies were associated with a lower incidence of frontoethmoid re-exploration (P = 0.048), and antrostomies with a lower incidence of maxillary re-exploration (P = 0.111), than were more limited drainage procedures. Sinus drainage performed simultaneously with neurosurgical drainage reduced the incidence of sinus re-exploration (P = 0.167), neurosurgical reexploration (P = 0.048), and length of hospitalization (P = 0.020). | lld:pubmed |
