“…In this study, we did not identify any remarkable morphology in the sphenoidal tubercle, and the mean STS values on the right and left sides were found to be quite close to each other. The lateral pterygoid muscle, the only muscle responsible for opening the jaw, attaches to the sphenoidal tubercle, and the sphenomandibular ligament, extending between the sphenoid spine and mandibular lingula, is tense when the jaw is open [12].…”

Purpose Our study aimed to investigate the sphenoid spine morphological characterization, as well as the distances to important surgical points and its relation to foramen spinosum localization. Methods On a total of 65 skulls, the distances of the sphenoid spine to articular tubercle, mastoid process, external opening of carotid canal, anterior edge of infratemporal crest, and the point where sphenosquamosus suture intersects with infratemporal crest were measured from both the right and left sides. The length of the sphenoid spine was measured and classified morphologically. Localization of foramen spinosum relation to sphenoid spine was evaluated. Results The sphenoid spine length was stastistically different which was found to be 6.71 ± 1.97 and 6.14 ± 1.93 on the rigt and left sides, respectively (p = 0.027). The most commonly encountered shape of the sphenoid spine on both sides was rectangular, followed by spine shape. The foramen spinosum was most frequently located anteromedially and least frequently located anterolaterally according to sphenoid spine. In our study, it was determined for the first time that the localization of the foramen spinosum is associated with the shape of the sphenoid spine on both the right (p = 0.012) and left (p = 0.016) sides. Conclusion Our study provides morphometric data on the sphenoid spine and reports the association between the localization of the foramen spinosum and the type of sphenoid spine. Sphenoid spine variations and their relationship with adjacent anatomical structures should be taken into consideration in middle cranial fossa surgeries.

In this study, we conducted a detailed morphological analysis of the lingula and foramen mandibulae, aiming to examine their anatomical characteristics and relationships within contemporary and medieval individuals. Our primary objective was to provide valuable insights to assist clinicians in minimizing potential intraoperative complications during anesthesia procedures targeting the inferior alveolar nerve. To accomplish this, we examined the mandibular structures of 22 adults, 11 children aged 6-12 from archaeological findings in the Târgu Mureș area, and 14 contemporary adults. Our observations encompassed the size, shape, and spatial relationships of the lingula and foramen mandibulae concerning various points along the ascending branch of the mandible. The study revealed a distinct order of lingula shapes among medieval children and adults, with the triangle, trapezoid, nodular, and assimilated shapes being most prevalent. In modern adults, the order of nodular and assimilated shapes was reversed. Additionally, oval foramina were more common in adults, while round foramina predominated in children. Notably, there was no statistically significant difference between children and adults in the distance from the most prominent point of the lingula to the anterior edge of the ascending branch. Our findings imply that the depth at which the inferior alveolar nerve can be accessed remains relatively consistent between children and adults. Furthermore, we identified a correlation between the relationship of the shape of the lingula and the position of the mandibular foramen, providing valuable insights for clinical practice.
