“…Future study on the developmental differences between the two foramen types is warranted in order to elucidate their clinical significance further. Additionally, how anatomical variations and various mechanisms for skull base fracture affect the true versus false skull base foramina should be studied in patient cohorts [9,14,41].…”

“…Both points are clearly identifiable regardless of condylar shape and volume. The center of the middle meningeal artery was also a reference point, such that variation in vessel diameter [12,32,33] and branching pattern [34][35][36] were not factors. The distance between the maxillary artery and condylar process was measured in the plane running through the deepest point of the mandibular notch, because that plane is easy to identify.…”

Purpose The close topographic relationship between vascular and osseous structures in the condylar and subcondylar region and marked variability in the arterial course has been revealed by both imaging and cadaveric studies. This study aimed to verify the previously published information in a large sample and to determine a safe surgical region. Methods We analyzed the three-dimensional time-of-flight magnetic resonance angiography images of 300 individuals. Results The mean distance between the middle meningeal artery and the apex of the condyle or the most medial point of the condyle was 18.8 mm (range: 11.2–25.9 mm) or 14.5 mm (range: 8.8–22.9 mm) respectively. The course of the maxillary artery relative to the lateral pterygoid muscle was medial in 45.7% of cases and lateral in 54.3%. An asymmetric course was evident in 66 patients (22%). The mean distance between the maxillary artery and condylar process at the deepest point of the mandibular notch was 6.2 mm in sides exhibiting a medial course (range: 3.7–9.8 mm) and 6.6 mm in sides exhibiting a lateral course (range: 3.9–10.4 mm). The distances were significantly influenced by age, gender, and the course of the maxillary artery. Conclusion Our study emphasizes the marked inter- and intra-individual variability of the maxillary and middle meningeal arterial courses. We confirmed the proximity of the arteries to the condylar process. Extensive surgical experience and thorough preparation for each individual case are essential to prevent iatrogenic vascular injury.

“…Hollinshead [7] stated similarities between the sinus of Hyrtl and the sinus of Kelch and indicated that they may actually describe the same structure. More recently, unilaterally present sinus of Hyrtl have been described in the literature and bilateral occurrences appear to have not been previously reported [8][9][10]. We previously reported a unilateral variant of the sinus of Kelch found in an 88-year-old at death female cadaver [11].…”

Knowledge of the variant anatomy of the intradural venous sinuses is important to anatomists and clinicians alike. Herein, we report a cadaveric case of the rare venous sinus of Kelch, which some have believed is a remnant of the cranioorbital sinuses. To our knowledge, only one other cadaveric case has been reported in the extant medical literature. Clinically, knowledge of such a variant venous sinus can minimize misdiagnoses such as when anatomical variations are noted on imaging. Surgically, such an understanding can avoid intraoperative complications such as iatrogenic hemorrhage.
