Abstract
Rhinogenous intracranial complications are considered as rare owing to the development of antibiotics. However, the number of reports on these complications has recently tended to increase because of their early detection by advanced diagnostic techniques, such as CT-scan. The authors report here the experience of a case in whom a brain abscess complicated to acute frontal sinusitis after a course of antibiotic treatment and frontal sinusotomy.
Further, rhinogenous intracranial complications appeared in Japanese literature were reviewed for incidence by primary lesions, etiology, details of complications and mortality rates. The primary lesion was located in the frontal or the ethmoidal sinus in many cases. These complications were classified by etiology into spontaneous, postoperative and post-traumatic, and the mortality rate was higher in spontaneous cases than in postoperative and post-traumatic ones. As complications, meningitis and brain and subdural abscesses were noted in many cases. There is a report that the incidence of subdural abscess has tended to increase in recent years.
