“…In a previous study conducted in Ghana, both males and females from the Dagaabas people had bilateral asymmetry between the heights of the right ear lobes (1.418 ± 0.207 cm, 1.437 ± 0.250 cm, respectively) and left ear lobule heights (1.435 ± 0.280 cm, 1.471 ± 0.235 cm, respectively). Regarding the widths of the right ear lobes, they were 1.547 ± 0.229 cm and 1.521 ± 0.195 cm, respectively, and the widths of the left ear lobes were 1.563 ± 0.249 cm and 1.544 ± 0.205 cm, respectively [ 17 ]. However, a study aimed at the Indian population concluded that the heights were not significantly different between both sexes, but the lobule widths of the right and left ears were significantly higher in males [ 18 ].…”

Background The human ear is a distinctive facial feature, revealing valuable information about ethnicity, gender, and age. Anthropometric measures play a crucial role in fields such as forensic medicine, prosthetics, and plastic surgery. The external ear, known for its diversity in structure and individual characteristics, has become a subject of interest in various populations. This study aims to determine the mean values of morphometric measurements for both right and left ears while exploring sexual dimorphism in ear dimensions. Methodology A prospective, observational, cross-sectional study was conducted among 200 volunteers from the eastern province of Saudi Arabia, comprising 98 males and 102 females, at the Department of Anatomy, Institute of Medical Sciences, Imam Abdulrahman Bin Faisal University. Participants were randomly selected from King Fahad University Hospital workers and patients. Using a Vernier caliper and after obtaining consent, various aspects of ear morphology were measured. The study employed statistical analyses such as the volunteers’ t-test, Pearson’s coefficient of correlation, and linear regression equations. Results In males, the mean total height of the right and left ears was 6.054 ± 0.5394 and 6.044 ± 0.5235 cm, respectively, while for females, it was 5.489 ± 0.4481 and 5.763 ± 4.8446 cm, respectively. The mean widths, heights, and other dimensions of the ears exhibited variations between genders. Conclusions The study provides comprehensive insights into the dimensions and indices of the pinna among the population of the eastern province of Saudi Arabia. The findings confirmed the presence of sexual dimorphism in the ear measurements, consistent with observations in other ethnic groups.

“…Hair transplantation, as a fundamental principle, involves creating channels in the recipient area proportional to the number of hair follicles being transplanted. [1][2][3][4] The general opinion is that the vascularity of the scalp in the recipient site is very high, and thus, necrosis is reported to be an extremely rare complication. In fact, the scalp is the richest region of the body in terms of superficial plexuses.…”

Purpose: The aim of this study was to determine the external ear values in Turkish young adults with 2-dimensional photogrammetry. Methods: One hundred males and 100 females aged between 18 and 25 years were included in the study. Individuals were photographed from both sides. Ear length (superaurel-subaurel, spa-sba), ear width (preaurel-postaurel, pra-pa), and the angle between the vertical axis of the auricle and the line between spa and sba (ear incline angle, eia) were measured in these photographs. Also, auricular index (pra-pa/spa-sba×100) was calculated. Results: The average values of the spa-sba, pra-pa, eia, and auricular index were found as 65.46±4.68 mm, 37.89±3.61 mm, 19.40±4.83 degrees, and 57.93±4.53 in males and 60.90±5.35 mm, 35.62±3.69 mm, 17.95±4.86 degrees, and 58.65±5.29 in females, respectively. While the values of spa-sba (P=0.001 for the right side and P=0.001 for the left side), pra-pa (P=0.001 for the right side and P=0.001 for the left side), and eia (P=0.024 for the right side and P=0.041 for the left side) were statistically higher for males than females, there was no statistically significant difference between the sex and the auricular index (P=0.404 for the right side and P=0.955 for the left side). Besides, there was no statistically significant difference between the sides for these 4 parameters (P=0.760, 0.409, 0.225, and 0.521, respectively). Conclusion: The authors believe that the results obtained for Turkish young adults can be used as reference values, which can be used in the diagnosis, follow, or surgical treatment of many diseases, forensic procedures, and planning esthetic surgery procedures.
