Posterior fossa abscesses. A review of 33 cases.

ABSTRACT

Thirty three cases of posterior fossa abscesses seen over a period of 20 years are reviewed. 84.8% of these were secondary to otogenic disease. Two abscesses were due to tuberculosis and one due to actinomycotic infection. The overall mortality was 12.1%. Total excision of the abscess with appropriate antibiotic therapy was associated with an operative mortality of 3.4%.
