Sexual Dimorphism in Nasal Width-to-Height Ratio Among Undergraduate Students
Abstract
The study examines sexual dimorphism in nasal width-to-height ratio among undergraduate students. The nose is an important facial structure that contributes to individual facial characteristics and exhibits measurable anatomical variation between individuals. Assessment of nasal proportions, particularly the relationship between nasal width and nasal height, may provide useful information for understanding sex-related differences in facial morphology. The study will determine nasal width-to-height ratios among male and female undergraduate students and compare the observed values between the sexes. Nasal width will be measured across the widest points of the nose, while nasal height will be obtained using standardized anatomical landmarks. The ratio will subsequently be calculated for each participant to provide an index of nasal proportionality. A cross-sectional descriptive research design will be adopted for the study. Undergraduate students who satisfy the established inclusion criteria will be selected using an appropriate sampling technique. Direct anthropometric measurements will be obtained using suitable instruments and standardized procedures to ensure consistency and accuracy. The collected data will be analyzed using frequency, percentage, mean, and standard deviation, while an appropriate inferential statistical technique will be used to determine whether differences in nasal width-to-height ratio exist between male and female participants. The study is expected to reveal variation in nasal width-to-height ratios among the participants and provide comparative information between the sexes. The findings are expected to indicate whether measurable differences in nasal proportions occur between male and female undergraduate students within the study population. Such findings may contribute to a better understanding of sexual dimorphism in external nasal morphology. The findings will be useful to anatomists, anthropologists, forensic practitioners, and researchers involved in facial anthropometry and human identification. The study may also provide baseline anthropometric information that can support comparative investigations of nasal morphology and contribute to the development of population-specific reference data. The study will conclude by providing information on sex-related variation in nasal width-to-height ratio among undergraduate students. It will recommend the use of standardized anthropometric techniques in studies of nasal morphology and encourage further research involving larger and more diverse populations to establish broader reference values.
