Sexual Dimorphism in Epiglottic Dimensions Among Young Adults

Abstract

The study examines sexual dimorphism in epiglottic dimensions among young adults, with emphasis on differences in selected morphometric measurements between male and female individuals. The epiglottis is a leaf-shaped elastic cartilage located at the entrance of the larynx and plays an important role in protecting the lower respiratory tract during swallowing by directing food and fluids away from the airway. Its morphology and dimensions may vary among individuals and may demonstrate sex-related differences, making its assessment relevant to anatomical, radiological, airway, and forensic studies. The study will assess selected dimensions of the epiglottis and compare the measurements between male and female young adults. The specific objectives will include measuring the length and breadth of the epiglottis, determining selected dimensions of its upper and lower portions, assessing its overall morphometric characteristics, and establishing whether significant differences exist between male and female participants. A cross-sectional descriptive research design will be adopted for the study. An appropriate sample of young adults will be selected using a suitable sampling technique. Epiglottic dimensions will be obtained using standardized imaging-based or anatomical assessment procedures and appropriate anatomical landmarks. The collected data will be analyzed using descriptive statistics such as frequency, percentage, mean, and standard deviation, while appropriate independent-group statistical tests will be applied to compare the measurements between male and female participants. The study is expected to reveal measurable variation in epiglottic dimensions among the young adults studied. Some selected measurements may demonstrate statistically significant differences between male and female participants, while other dimensions may show considerable overlap between the two groups. The findings are expected to provide information on the extent of sex-related variation in epiglottic morphology within the study population. The findings will be useful to anatomists, radiologists, otolaryngologists, anaesthetists, speech and language professionals, forensic anthropologists, and other healthcare practitioners involved in the assessment of the upper airway. The study may provide useful reference information for understanding normal sex-related differences in epiglottic morphology and may support the interpretation of radiological findings and anatomical variations relevant to airway assessment and clinical procedures. The study will conclude by documenting the pattern of sexual dimorphism in selected epiglottic dimensions among young adults. It is recommended that standardized anatomical and imaging-based procedures be used when assessing epiglottic morphology, while further studies involving larger and more diverse populations should be conducted to establish broader sex-specific reference data on epiglottic dimensions.
