Abstract

Background. The morphometric parameters of the cerebral cortex area on the upper surface of the temporal lobe, located between the transverse temporal bends and the end of the lateral groove of the cerebrum in this area of the temporal lobe, have been poorly studied by anatomists. The lateral sulcus is anatomically closely connected with the middle cerebral artery, which must be taken into account in the surgical treatment of intracerebral islet tumors. The anatomy of the lateral sulcus is also of great importance for angiography. The purpose of this research is to identify sexual, bilateral and age-related variability in the length of the sulcus lateralis (SL), the length and width of the operculum temporale (OT) in adults. Material and methods. 79 formalin-fixed encephalon preparations obtained in autopsy of 60 men and 19 women aged 22–73 years were examined. The study material is divided into 3 age groups: 1st and 2nd periods of mature and old age. Results and conclusions. The length of the SL does not differ between men and women (p > 0.05). The left SL in men is 12.5 % longer, in women 13.7 % (p < 0.001–0.05) longer than the right. In the 1st mature age period, the left SL is longer – by 13.9 %; in the 2nd period of maturity – by 11.4 %; in the elderly, it is 2.2 % shorter than the right (p < 0.001–0.05). No significant age differences were recorded. The width of OT in men is 8 % more (p < 0.05). No significant bilateral differences were found in men and women as well as in the age groups studied. In the 2nd maturity period, it is 9.0 %, and in old age it is 16.8 % already than in the 1st maturity period (p < 0.05). The length of OT does not differ between men and women (p > 0.05). Left OT is longer than right in men by 50.0 %, in women by (28.7 %) (p < 0.001–0.05). The left OT is longer than the right in the 1st mature age period – by 44.4 %; in the 2nd mature age period – by 54.7 % (p < 0.001–0.05). No significant age differences were recorded.
