Correlation Between Nostril Breadth and Nasal Breadth Among Undergraduate Students

Abstract

The study examines the correlation between nostril breadth and nasal breadth among undergraduate students, focusing on the association between these two external nasal dimensions. Nostril breadth and nasal breadth are important components of external nasal morphology and contribute to the assessment of nasal proportions and individual anatomical variation. Understanding the relationship between these measurements may provide useful information for anthropometric studies and the documentation of normal nasal characteristics. The study will determine the nostril breadth and nasal breadth of undergraduate students using standardized anatomical landmarks and direct anthropometric measurement procedures. Nostril breadth will be assessed across the appropriate widest transverse dimension of the nostril region, while nasal breadth will be measured across the widest portion of the external nose. The study will describe the distribution of both measurements and determine the degree of association between nostril breadth and nasal breadth among the participants. A cross-sectional descriptive research design will be adopted for the study. Undergraduate students who meet the established eligibility criteria will be selected using an appropriate sampling technique. Data will be collected through direct observation and standardized anthropometric measurements using suitable measuring instruments, with consistent participant positioning and anatomical landmarks maintained throughout the assessment. The collected data will be analyzed using frequency, percentage, mean, and standard deviation, while Pearson correlation analysis will be used to determine the relationship between nostril breadth and nasal breadth. The study is expected to reveal measurable variation in nostril breadth and nasal breadth among the undergraduate students. The correlation analysis is expected to indicate the direction and strength of the association between the two measurements. The findings may demonstrate whether individuals with greater nasal breadth tend to have corresponding differences in nostril breadth within the study population. The findings will be useful to anatomists, anthropologists, forensic practitioners, clinicians, and researchers involved in facial anthropometry and external nasal morphology. The information may provide reference data for comparative studies of nasal dimensions and contribute to a better understanding of normal variation in the external nose. It may also be relevant to clinical assessment, reconstructive procedures, and studies involving nasal morphology and facial proportions. The study will conclude by establishing the nature and strength of the correlation between nostril breadth and nasal breadth among undergraduate students. It is recommended that standardized anatomical landmarks and measurement procedures be maintained when assessing nasal dimensions to improve measurement reliability and comparability. Further studies involving larger and more diverse populations are recommended to provide broader reference information on the relationship between different external nasal measurements.
