STATISTICAL OBSERVATIONS OF OTOGENOUS MENINGITIS IN OUR CLINIC FOR THE PAST 10 YEARS

THE STASTICS OF THE CASES RECORDED DURING 25 YEARS SINCE 1922

Abstract

1) For the past 10 years, 73 cases of otogenous intracranial complications were treated, in which 48 meningitis, 34 sinus thrombosis and 6 brain abscess were observed.
2) The prognosis of meningitis was better in cases due to chronic otitis media than that of acute. The former were 15 cases, in which 8 cases were cured, while the later were 33 cases, in which 8 cases were cured.
3) For the spinal drainage, Tanaka-Oda's method (continuous drainage under the definite positive pressure) were employed with excellent results as well as laminectomy.
4) In these 108 cases of meningitis (1922-1936 60 cases; 1937-1946 48 cases), 32 cases (29.6%) were cured.
