Sinogenic and otogenic brain abscesses--a review of 63 cases occurring at Toronto General Hospital, 1956-75.

Abstract

Sixty-three cases of brain abscess resulting from ear and paranasal sinus infections were reviewed. These patients were seen at the Toronto General Hospital from 1956-1965 and from 1969-1975. Comparisons are made relating to site, age and sex incidence, mortality rates, bacteriology, and rate of associated meningitis. Modern diagnostic methods are reviewed with particular emphasis on the use of the C.T. scanner.
