Recent studies have suggested that calcifications in the petrosphenoidal ligament (PSL) may increase the likelihood of abducens nerve injury, resulting in idiopathic paralysis of the lateral rectus muscle of the eyeball. However, the literature is still scarce in determining the occurrence of these calcifications and associated factors. Therefore, the objective of this study was to evaluate the occurrence of calcifications in the PSL in dry human skulls from Northeastern Brazil. The presence of areas indicative of calcifications in skulls belonging to the Federal University of Alagoas and the Federal University of Pernambuco were evaluated. Each ligament was classified into four patterns based on morphometric parameters, with the aid of a digital caliper: (1) Absence of calcifications; (2) < 50%; 3- 50% to < 100% and, 4- complete calcification. Statistical analyzes were tabulated in the jamovi statistical software, version 2.2.5, with a significance level of 5%. 65.5% of the skulls showed some degree of calcification. 56.4% had calcification on the right side and 40% on the left side. The most common classification was type 2. The frequency of calcification was statistically higher on the right side. The frequency of calcification in the PSL was high in the sample of skulls evaluated and more frequent on the direct side. More studies are necessary to better elucidate its occurrence, relationship with the sides of the skull, gender, age and possible clinical complications.
