The temporal operculum is a region of thetemporal lobe upper surface, which is bounded at the frontby transverse temporal gyri, and from behind – by the end ofthe lateral cerebral sulcus.Aim of study: to identify the shape and the dimensionalfeatures of the temporal operculum in people aged 1–21.Fixed brain preparations (n = 47) were used to measurethe depth of the lateral sulcus at the level of the temporaloperculum, and the temporal operculum length along itsouter edge; the temporal operculum area was calculated aswell. The studied material was divided into groups followingage periodization: early childhood (n = 8); the first periodof childhood (n = 18); the second period of childhood (n= 7); adolescence (n = 5), youthhood (n = 9). The studyproduced average values for the lateral sulcus depth, thetemporal operculum length and area in people aged 1–21.The triangular shape of the temporal operculum has beenfound to be the most common. The temporal operculumarea in early childhood and the first period of childhood, aswell as the temporal operculum length in early childhoodprevail in the left hemisphere (p <0.05). Viewed fromthe age aspect, the depth of the lateral sulcus varies lesssignificantly than the length and the area of the temporaloperculum. The temporal operculum area correlated morewith the operculum length rather than with the depth of thelateral sulcus
