Assessment of age changes and gender differences based on anthropometric measurements of ear: A cross-sectional study

Aim: To assess the age changes and gender differences based on anthropometric measurements of the ear and to create a database for the reported population. Materials and Methods: This study was conducted among 200 individuals who reported to private dental teaching hospital as outpatient. The study population was explained about the procedure, and informed consent was obtained. The size of the auricle was measured bilaterally. The study population was subdivided into three subgroups. Group I included individuals between 20 and 39 years, Group II between 40 and 59 years, and Group III above 60 years. Results: The total ear index among women with mean and standard deviation was 4.97 ± 0.6 cm, and men were 5.02 ± 0.4 cm. The lobe index among men with mean and standard deviation was 1.153 ± 0.0163 cm, and women were 1.243 ± 0.0147 cm with a significant P < 0.0001. Conclusion: The anthropometric measurements of ear index were higher in men than women, with no age changes after 20 years of age for both men and women. Hence, this data are considered reliable and can be used for various purpose including forensics, identification, plastic surgeries, and research.
