Sexual Dimorphism in Supraorbital Foramen Dimensions Among Young Adults

Abstract

The study examines sexual dimorphism in supraorbital foramen dimensions among young adults, with emphasis on differences in the size and morphology of the supraorbital foramen between male and female individuals. The supraorbital foramen is an important opening along the superior margin of the orbit that transmits the supraorbital nerve and associated blood vessels. Knowledge of its dimensions and anatomical variation is important for understanding craniofacial anatomy and may provide useful information for clinical, radiological, and forensic applications. The study will assess selected dimensions of the supraorbital foramen among young adult males and females using standardized anatomical landmarks and appropriate imaging-based or osteological measurement procedures. The specific objectives will include determining the length, breadth, and other measurable dimensions of the supraorbital foramen, documenting its morphological characteristics, assessing right and left side variation where applicable, and comparing the observed measurements between male and female groups. A cross-sectional descriptive research design will be adopted for the study. An appropriate sample of young adults or suitable cranial imaging or osteological specimens will be selected using an appropriate sampling technique. Measurements will be obtained using standardized anatomical landmarks and appropriate measurement procedures. The collected data will be analyzed using descriptive statistics such as frequency, percentage, mean, and standard deviation, while appropriate inferential statistical tests will be applied to determine significant differences between male and female groups. The study is expected to reveal measurable differences in selected supraorbital foramen dimensions between male and female young adults, with some dimensions potentially demonstrating statistically significant sexual variation. Variations in the shape and configuration of the foramen may also be observed within the study population. The findings are expected to provide useful anatomical reference values while demonstrating that the dimensions of the supraorbital foramen may vary across individuals. The findings will be useful to anatomists, radiologists, ophthalmologists, oral and maxillofacial surgeons, plastic surgeons, forensic anthropologists, and other healthcare professionals involved in the assessment of craniofacial structures. The study may contribute to improved understanding of sexual variation in supraorbital foramen morphology and provide reference information for radiological interpretation, regional anaesthesia, surgical procedures, and forensic identification. The study will conclude by providing information on sexual variation in the dimensions and morphology of the supraorbital foramen among young adults. It is recommended that standardized anatomical and imaging-based measurement procedures be maintained when assessing the supraorbital region, while further studies involving larger and more diverse populations should be conducted to establish broader anatomical reference data.
