“…The distance between SOF or SON and nasal midline on both sides ranged between 20 mm and 29 mm. There was no difference in measurements of the parameters bilaterally between ancestries or sexes in Malaysia (Tables 3,4), and similar results were exhibited in the Egyptian, Indian, and Brazil populations [1,20,30].…”

“…In the Egyptians, the mean horizontal diameters of SON were 7.55 mm (right) and 7.84 mm (left) in male and 6.51 mm (right) and 6.84 mm (left) in female. Thus, the horizontal diameter of SON or SOF appeared to be broader in the Egyptians than Malaysians [20]. The mean horizontal diameter of SOF was greater in male than female and exhibited greater values on the right side than the left side in both sexes ( Table 5).…”

“…23% Malay, 18% Chinese, and 20% Indian, while the combination of right SON and left SOF was the least common, i.e., 4% Malay, 4% Chinese, and 3% Indian ( Table 2). In the Egyptians, bilateral SON was the most common attribute displayed (30.51%), while bilateral SOF (18.64%) was the least [20]. In the Koreans, the unilateral notch was the most common feature, which accounted for 42.3% and Fig.…”

Objective: A clear knowledge of the location of supraorbital foramen (SOF) is vital for the surgeons, particularly in endoscopic surgery and regional block in crania. The aim of this study was to analyze SOF and notch in skulls of various ancestries.Methods: The anatomical variations of SOF and notch were examined in 100 adults skulls (55 males and 45 females) of the Malay, Chinese, and Indian ancestries by traditional measurement made with the Osirix software. The parameters included distance between supraorbital structure and nasal midline, shape, and transverse diameter of the SOF.Results: It was manifested that bilateral supraorbital notch (SON) was the most prevalent combination in both sexes and ancestries (61%), while combined SON and foramen (11%) were the least prevalent characteristic. The mean distances of supraorbital structure from nasal midline bilaterally in males were slightly greater than females. The horizontal diameter of SOF, notch and their distances from the nasal midline showed no difference between ancestries.Conclusion: This study would serve as a guide for the surgeons when surgery is performed on the scalp. It can help in the precise determination of reference points for supraorbital nerve blockade for the Malaysians. In addition, the variations exhibited in supraorbital measurements inevitably revealed that sex and ancestry should be taken into consideration when choosing samples for anatomical classification of crania.

“…The study of 59 (32 males and 27 females) adult human skulls in Egypt meticulously described the structure of supraorbital foramen. They found that bilateral supraorbital notch accounted for 30.5 %, bilateral SOF 18.6 %, one-sided notch and a foramen on the other side were seen 11.9 % of the total samples, 22.0 % had bilaterally supraorbital ridge, and 8.5 % showed a ridge on one side and a notch on the other side (Sheikh et al, 2013).…”

The aim of this study was to study the anatomical landmarks and variations of supraorbital, infraorbital, and mental foramina. One hundred and sixty Thai dry skulls were randomly selected from the Forensic Osteology Research Center. The distances of the parameters were measured by using Vernier caliper. The supraorbital foramen could be found in a notch form 13.8 %, single supraorbital foramen accounted for 82.5 %, and supraorbital foramen with an accessory foramen represented 3.8 %. Single infraorbital foramen was found 90.0 %, and infraorbital foramen with an accessory foramen represented 10.0 %. Single mental foramen was observed 96.6 %, and the frequency of mental foramen with an accessory foramen was determined 3.4%. The majority of infraorbital foramina (48.0 %) was detected above the second premolar area. 19.0 % of the infraorbital foramina was seen in the region between the first premolar and the second premolar, and 22.8 % of the infraorbital foramina was located between the second premolar and the first molar. The infraorbital foramen is anatomically positioned above the first molar (10.2 %). The majority of mental foramina (53.5 %) can be identified below second premolar area. The region between the first premolar and the second premolar is the site for the mental foramen 26.0 % of the total variations. The region between the second premolar and the first molar is the site for the mental foramen 16.9 % of the total variations. The mental foramen is approximately situated below the first molar (3.6 %). The present study of anatomical variations of various foramina demonstrates a useful application in cosmetic and ophthalmic plastic surgery. The findings could improve the efficacy of the surgeons and accuracy for the indicated localization of these foramina during maxillofacial operations and local anesthetic procedures.
