“…Results presented the presence of four combinations of bilateral SON as the most prevalent combination (61%), followed by bilateral SOF (15%) and the combination of both SOF and SON as the least observed manifestation (11%) ( Table 1). These results were comparable with the study by Tomaszewska et al who showed that bilateral SON to be the highest combination manifested in skulls coming from warm and temperate climate areas [23].…”

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 SOF was present in 6.67% of the subjects, 3.81% in the right and 5.71% in the left side. The shape of human cranium and distribution of the supraorbital structures may be influenced by numerous factors, both genetic and environmental, and also by the climate [27], [28]. Tomaszewska et al [28] supposed that the type and frequency of the supraorbital structures in modern human population may depend on the climatic conditions in which the population lived.…”

“…The shape of human cranium and distribution of the supraorbital structures may be influenced by numerous factors, both genetic and environmental, and also by the climate [27], [28]. Tomaszewska et al [28] supposed that the type and frequency of the supraorbital structures in modern human population may depend on the climatic conditions in which the population lived. Analyzing 1978 orbits from the skulls collected in three climatic regions, warm, temperate and cold, these authors discovered that the frequency of SON was the highest in the sample from warm climates (54.5%), and the lowest in the sample from cold climatic conditions (44.0%).…”

In this study, we aimed to estimate the anatomical variations of the supraorbital notch or supraorbital foramen (SON/F) using three-dimensional computer tomography (3D-CT) volume rendering and evaluate these variations related to gender and side. One hundred and five adults (53 men and 52 women), aged 21 to 83 years, without any trauma or bone malformation of facial bones, were included in our study. Presence of SON/F, its shape, diameter in millimeters, and distance from the reference point were recorded. The most common presentation of the supraorbital passage was single SON and it was noted in 51.43% on the right and in 57.14% on the left skull side. The single SOF was noted in 3.81% on the right and 5.71% on the left skull side. Double notch was found in 1.90% on the right and in 0.95% on the left side, while double foramen was not found in subjects included in our study. SON/F was not found in 42.90% and 36.20% on the right and left side, respectively. The average SON diameter was 3.7 ± 0.9 mm, and the average SOF diameter was 1.7 ± 0.5 mm. The average distance of SON/F to the facial midline was 21.9 ± 3.1 mm. The average distance of SON/F to the temporal crest of the frontal bone was 26.0 ± 3.0 mm and to the frontozygomatic suture was 27.5 ± 2.6 mm. Statistically significant difference was observed between the right and left side for the distance from SON/F to frontozygomatic suture (p < 0.01). No significant difference was found between the left and right sides in the other measurements (p > 0.05). Statistically significant differences were found between males and females for some of these parameters. The results of this study provide useful information about the location of the supraorbital neurovascular bundle and may be used in preoperative evaluation.
