Abstract

The complexily in development of the dural sinus may result in many variations. Studies are being done on the variation of the straight sinus for clinical application of neurological diagnosis and operation. However, no data is available on Koreans, which made this study necessary. The present study was made on 50 Korean adult cadavers (average age of 67). The results were as followlng. 1. A bulbous formation of the rostral aspects of the straight sinus was present in 22 cases(44%). 2. Complete double straight sinus was present in 3 cases(6%). 3. Partial septum was observed in 8 cases (16%) with varied position and length. 4. The straight sinus terminated into both transverse sinuses(52%), the left transverse sinus(24%), the confluence of sinuses (18%), and the right transverse sinus(6%). 5. Average length and width of the straight sinus were 48.5mm and 5.9mm, respectively. 6. Nineteen cases(38%) showed no tentorial sinus drainage into the straight sinus on both sides. Number, size and terminationes.
