“…It is confused with the sphenoid spine in some studies [11,15]. It has been reported that the sphenoidal tubercle was found to be giant bony prominence in a case and it may pose an obstacle to surgical access to the skull base [11]. 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.…”

“…Another surgical reference point used in infratemporal fossa surgeries is a bony prominence located at the anterior end of the infratemporal crest, referred to as the sphenoidal tubercle in the literature. It is confused with the sphenoid spine in some studies [11,15]. It has been reported that the sphenoidal tubercle was found to be giant bony prominence in a case and it may pose an obstacle to surgical access to the skull base [11].…”

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.

The pterygoideus proprius muscle can be found incidentally in the infratemporal fossa, where it is spatially associated with the muscles of mastication, the maxillary artery, and the trigeminal nerve and its branches. Anatomists have described the muscle in various ways over the past 160 years, chiefly as a musculotendinous structure that originates from the infratemporal crest of the sphenoid bone and inserts into the lateral pterygoid plate and the lateral pterygoid muscle. It is present in non‐human primates, albeit rarely, with similar anatomical findings. Embryologically, the pterygoideus proprius is thought to have developed from the first pharyngeal arch mesenchyme along with other muscles of mastication. Its close association with the maxillary artery and trigeminal nerve suggests possible clinical significance in trigeminal neuralgia and temporomandibular joint disorders. The literature was reviewed systematically to detail the historical background of research on the pterygoideus proprius muscle and explain its morphology, prevalence, embryology, and potential clinical significance. Despite its rarity, we propose that it is important to recognize its presence when the infratemporal fossa is approached.
