METHOD FOR INTEROPERATIONAL DETECTION OF SIGMOID SINUS PRESENTATION

摘要

FIELD: medicine, otorhinolaryngology. SUBSTANCE: one should evaluate the degree of suprasinusal fossa by a tetramark system to measure its longitudinal and cross-sectional size values. In case it is not or poorly pronounced, and its longitudinal size corresponds to 3,2±0,3 mm and cross-sectional one - to 2,8±0,2 mm it is possible to establish the presentation of sigmoid sinus. EFFECT: more simplified, reliable and accurate method for detection. 2 ex
