THE clinical and pathologic aspects of otogenic abscesses of the brain have already been widely and thoroughly discussed. Among the various pathologic conditions which may cause them, deep epidural abscesses resulting from perilabyrinthine suppurations deserve particular interest. This is seen clearly in the 3 cases reported in this paper, in which the abscesses showed unusual diagnostic and pathogenetic features. All the cases ended fatally, and the brain and temporal bones were available for histologic examination.
