“…Our investigation revealed that the total height of the left ear in males was 6.044 ± 0.5235 cm, while in females, it was 5.763 ± 0.48446 cm. This aligns closely with the findings from Turkey, supporting the consensus across studies that males tend to exhibit greater TEH, a trend observed in both the Thai and Sudanese Arab populations [ 14 , 15 , 19 , 20 ].…”

“…In the Thai population, the height of the left ear lobe was found to be higher in females (1.94 ± 0.39 cm) than in males (1.86 ± 0.36 cm). However, the widths of the right and left lobes and the right lobule heights were greater in males [ 15 ].…”

“…In a Turkish study, the total height of the left ear was reported as 6.31 ± 0.36 cm in males and 5.97 ± 0.3 cm in females [ 19 ]. Similarly, a study from Thailand yielded measurements of 6.73 cm and 6.36 cm for males and females, respectively [ 15 ]. Our investigation revealed that the total height of the left ear in males was 6.044 ± 0.5235 cm, while in females, it was 5.763 ± 0.48446 cm.…”

“…In the Turkish population, the total height of the right ear displayed no significant differences between males (6.29 ± 0.35 cm) and females (5.97 ± 0.3 cm) [ 14 ]. Conversely, in the Thai population, a significant difference in the same measurement was observed, with values of 6.7 cm for males and 6.3 cm for females [ 15 ]. Our study highlighted significant sexual dimorphism in the left ear, with measurements for the right ear in males at 6.054 ± 0.5394 cm and in females at 5.489 ± 0.4481 cm.…”

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.

“…For identification purposes and product design suitable for various populations, anthropometric data is needed [12]. Auricular measurements have been carried out in different populations such as Sudan [13], Korean [9], Egypt [14], Chinese [15], Indian [11], and Thai [16]. In Nigeria such measurements have also been done in various tribes such as Ijaws [17], Hausas [12], Yoruba [18], Urhobos [19] Okrika [20], and Igbos [21].…”

Background: The auricle is an important cephalofacial part of the human body that is of forensic importance that portrays information about one’s age, sex, race and ethnic group. Aim: This study was therefore conducted to establish auricular anthropometric data and sexual dimorphic parameters of Uturu indigenes in Southeastern Nigeria. Materials and Methods: A total of 370 subjects (185 males and 185 females) of Uturu indigenes who met the inclusion criteria were enrolled in the study. Auricular measurements which include auricular length and width and lobular length and width, as well as lobular attachments were obtained in inches. Data obtained was analyzed using SPSS version 23.0. Results: Total mean auricular length, auricular width, lobular length and lobular width in males was 2.11, 1.35, 0.66 and 0.46 respectively while same parameters in females were 2.06, 1.22, 0.66 and 0.44 respectively. No significant sexual dimorphism was observed in the measured parameters except for auricular width (P=0.01). Free earlobe was prevalent (68.92%: n=255) in the study population especially among the female subjects. Conclusion: The mean values for all auricular measurements were higher in males than in females except for lobular length which was the same in both sexes. Results The findings from this study provide useful evaluation of the auricular morphological characteristics among the study population will be useful in the documentation of auricular morphometric data, especially within Nigerian population.

Objective: to determine the typological features of the intertragal notch (ITN) shape of the auricles (AU) in young men. Material and methods. After somatotyping and cephalotyping of 140 young men both right and left AU were photographed. 25 marks were applied on the images of AU along the margin of the ITN by digitizer tpsDig2 2.31. We performed a procedure for superposition of label configurations using the method of generalized Procrustean analysis using MorphoJ 1.06d soft. Procrustean coordinates were determined, characterizing the variability of the ITN shape of the right and left AU. A one-way AN OVA was carried out on the obtained data with the determination of Goodall's F-criterion, which was used to determine the strength of the influence of the cephalotype and somatotype of the young men on ITN shape both left and right AU. The significance level of the F-criterion is set at 0.05. To visualize the change in the shape of the ITN of AU of the corresponding side, the method of transformation grid was used. Results. As a result of ANOVA, a statistically significant influence of the somatotype of young men on ITN shape only in the left AU was established (F =1.98; p<0.0001). The significance level of the F-criterion in determining the strength of the influence of the cephalotype on ITN shape of both AU exceeded the critical value. As a result of discriminant analysis of ITN shape in groups of young men belonging to different morphotypes, models were obtained that allow for the correct classification of ITN. The classification accuracy of such models in some cases exceeds 90%. Conclusions. Variability in the form of ITN is more associated with the somatotype than with the cephalotype of young men. The shape of ITN differs in young men with different morphotypes.
