Otogenic intracranial complications are described in detail in otologic textbooks because of their severity. The incidence and interest in otogenic intracranial complications have markedly decreased. Authors think this improvement of otogenic intracranial complication level is due to development of the medicine which included antibiotics, methods of treatment, the living standards of the public, and the recognition of otogenic complications by the public. The incidence of it may be different in the various areas of Korea however, authors report 19 cases of otogenic intracreanial complications for 12 years from 1973 to 1985. The results are as follow : 1) Otogenic intracranial complications in order of frequency were meningitis (10 cases ;52.7%), brain abscess (5 cases ; 26.2%), otitic hydrocephalus (2 cases ; 10.5%), epidural abscess (1 case ; 5.3%) and subdural abscess (1 case ; 5.3%). 2) The age distribution showed 15 cases (78.8%) in the 2nd and 3rd decade and out of the 19 cases 17 were male. 3) 7 cases (36.8%) had past history of postauricular abscess. 4) Spinal tappings were performed in 17 cases (89.4%). 5) Bacteriological study from ear discharge showed Gram negative organisms. The most common infected organism was Proteus species (62%). Multiple infection was noted in 4 cases (21%). 6) In 5 cases of brain abscess, the abscess was located in temporal lobe in 3 cases and cerebellum in 2 cases. 7) Methods of operation were 8 radical mastoidectomy, 1 modified radical mastoidectomy and 1 simple mastoidectomy. 8) Exposed organs were 7 dura, 2 facial nerves, 2 lateral sinuses, and 1 horizontal semicricular canal.
