Variations in the location of the lateral sulcus of the brain in men with different skull shapes

Objective: to identify the most accurate craniometric scheme for determining the anatomical location of the lateral sulcus of the brain in adult men with different skull shapes. Material and methods. The study included computed tomograms of 257 adult men, of whom 113 belonged to the I period of adulthood (21–35 years), and 144 to the II period of adulthood (36–60 years). Methods of craniocephalometric analysis were used to assess the localization of the lateral sulcus. Craniometric schemes were constructed according to the techniques of Taylor – Haughton, Broca, Krönlein (Kocher – Keen), and Rhoton. Results. The most common skull shape among the study participants was brachycranial (46,9% among men of the I period of adulthood and 56,2% among men of the II period of adulthood). In dolichocrania, the location of the lateral sulcus best corresponded to the Rhoton method (82%; p=0.04 – men of the I period of adulthood, p=0.015 – men of the II period of adulthood). In men with a brachycranial skull shape, the greatest correspondence was demonstrated by the Taylor-Haughton method (78%, p=0.020 – men of the I period of adulthood, p=0.003 – men of the II period of adulthood), and with a mesocranial shape – the Krönlein method (p>0.05). Conclusion. Optimal schemes were identified for determining the location of the lateral sulcus of the brain using computed tomography in men with dolichocranial and brachycranial head shapes. For men with mesocrania, an optimal scheme was not revealed, which makes it necessary to further study acceptable approaches for this craniological group.
