Izawa and his associates report on a case of "mucosus" infection of the temporal bone. History reveals the patient had an attack of acute otitis media about 5 months previously to the time of present examination but the aural discharge, though largely diminished in amount in the meantime, has not completely ceased. Insufflation of Eustachian tube was ineffectual towards relief in symptoms of impaired hearing and persistent tinnitus. Examination of the patient showed only a slight degree of inflam-matory infiltration of tympanic membrane but, the offending agent was proven to be "mucosus" bacteriologically. Roentgen ray examination re-vealed involvement of petrous pyramid and mastoid bones in the subacute inflammatory process. Biopsy specimens obtained from 6 dif-ferent areas of the temporal bone showed hyperplastic osteitis in greater number of them but those from deeper parts showed areas of necrosis. Authors conclude that unabating symp-toms of chronic otitis media in this patient seems to be pertinent to presence of chronic otitis media in this patient seems to be pertin-ent to presence of chronic oseteitis in the tem-poral bone.
