- Abstract
Introduction: the sella turcica is a structure of the median region of the sphenoid bone. Variations in its morphology are relevant as it is a region subjected to several surgical procedures, mainly related to the pituitary gland. The aim of this study was to analyze the morphology of sella turcica and its sexual dimorphism in Northeastern Brazil. Material and Methods: the research was carried out at the Human Anatomy Laboratory of the Federal University of Paraíba (UFPB) and at the Anatomy Laboratory of the Nova Esperança College (FACENE/FAMENE - João Pessoa, Paraíba, Brazil). Thirtyone skulls were analyzed. In qualitative analysis, the sella turcica was classified as U-shaped, J-shaped, and Flat-shaped. The morphometric analysis was done through a digital pachymeter and the data analyzed statistically, to obtain a possible relation between morphometry and sex, besides the relation between sella and skull measurements. Values of p = 0.05 were considered significant. Results: the most prevalent sella in this study was J-shaped (51.6%). No differences (p > 0.05) between sexes in all measures were found, but male skulls have high values expected for bitemporal width and maximum width. There was positive linear correlation between the anteroposterior diameter of sella and two measures: sella turcica length and sella turcica width. Furthermore, bitemporal width and sella turcica width also present positive linear correlation. The results point to original findings for this population. Conclusion: knowledge of the morphology of the sella is essential to plan safer surgical approaches in the pituitary gland or related anatomical structures.
