Anthropometric Measurements of Ear Lobule in Population of Uttar Pradesh
The external ear is a defining feature of the face. It helps make one have the "normal" look with an aesthetically fine appearance. A prominent ear is the commonest congenital deformity of the external ear. External ear consists of auricle or pinna and external acoustic meatus. It collects sound waves and conducts them on the external acoustic meatus inward to the tympanum. The present study is attempted provide anthropometric data on normal adult male and female ear lobule from population of Uttar Pradesh. Aim: To study the anthropometric measurements of ear lobule in population of Uttar Pradesh. Materials and Methods: This study was conducted on 420 adults (210 males and 210 females) who were randomly selected from the population of Uttar Pradesh, using a vernier calipers. The parameters measured were, ear lobule length and width of both sexes. Results and discussion: In our study, there was highly significant difference between the two sides Conclusion: Knowledge of normal ear dimensions is important in the diagnosis of congenital malformations and acquired deformities, and in planning of treatment. The data presented in this study would help the clinician to produce an anatomically correct ear during its reconstruction.

Background: The human ear is unique and auricular biometrics has been adopted as reliable aid in personal identification in forensic sciences. The ear morphometry plays a critical role in reconstructive auricular and peri-auricular surgery to reproduce an anatomically correct and esthetically pleasing ear. Objectives: To determine mean values of linear ear measurements and their variation with age, sex and side. Materials and Methods: The study was conducted in 192 students consisting of 98 females and 94 males, in College of Medical Science, Bharatpur, Chitwan, Nepal. Students were categorized in three age groups (17-18 years, 19-20 years and >=21 years). Both ears and their lobule length were measured with standard Vernier caliper. The data was analysed using SPSS version 16.0. Results: The mean values of EW and LW were more on the right side than on the left in both males and females whereas mean LH was more on the right side in females only. There were significant differences in linear measurements of ear between males and females (p<0.05), the EL, EW, LL and LW being higher in males than females. Aging had a significant effect on EH in both males and females. Conclusion: This study provides mean values of different morphometric measurements of right and left ears in both sexes, which may be used as reference data to guide plastic surgeons during auricular reconstruction and may assist the forensic pathologist in the identification of a living or deceased individual.
The Morphometric Variations of External Ear between Asian and African Population
The morphometric characteristics of the external ear is different for every individual. This unique characteristic of the external ear morphometry can be used for identification of an individual in various circumstances where ear is considered as an evidence. Aim and Objectives: To compare the morphometric variations of external ear between Asian and African population. Material and Methods: The study was conducted on a total of 36 people with 20 male and 16 female which includes 16 subjects from African population and 20 from the Asian population. A total of nine ear parameters including two indices were recorded using a digital Vernier's calliper and two indices were calculated for both the ears. Independent t-test was performed to evaluate significant relationship between different variables. Results: After the analysis of the independent t-test results, few parameter showed significant difference (p<0.05) between the Asian and African groups. The details of the results are discussed below.
Anthropometric Assessment of the Normal Adult Human Ear
Annals of maxillofacial surgery
Knowledge of anthropometric measurements of the external ear is important as variations exist based on gender, age and ethnicity. This study has derived anthropometric data pertaining to the external ear in the Maharashtrian population. Nine variables of the external ear were measured in 505 Maharashtrian adults (aged 18-64 years) using photoanthropometric methods. Descriptive data and the left-right symmetry for the study population were obtained. These data have applications in screening for or monitoring diseases, otoplastic surgery, forensics, industrial design, apparel design and ergonomics.

Introduction: Anthropometry is an essential technique to understand the variations in the human body that is implicated during various reconstructive surgical procedures, and for the identification of individual during crime scene in forensics. Analysis of ear morphology plays a role in understanding the sexual dimorphism and stature in the human population. It has been found that the ear morphology changes from one region to another. Aim: To study the morphometric parameters of the ear for stature estimation, and to identify sexual dimorphism in north Indian population. Materials and Methods: This cross-sectional study of 200 subjects (100 males and 100 females) aged 17-25 years was conducted in the Department of Anatomy, Institute of Medical Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India. The study participants were selected from the MBBS, BDS and Nursing undergraduates studying in Banaras Hindu University (BHU). The various aspects of ear morphology (ear lengt...
Ear morphology and anthropometry: gender and age differences in Indian college students
Indian Journal of Clinical Anatomy and Physiology, 2023
Introduction: The human ear is an important organ that serves as a sensory input for sound and balance. Ear morphology can vary greatly between individuals and can be influenced by various factors such as age, sex, genetics, and environmental factors. This study aimed to investigate ear dimensions and anthropometry of a sample of Indian college students. Materials and Methods: A total of 100 Indian college students were included in this cross-sectional study. Ear measurements including total ear height (TEH), ear width (EW), lobule height (LH), and lobule width (LW) were obtained using digital calipers. Lobule index (LI) and ear index (EI) were calculated using the following formula: LI = LH/TEH x 100 and EI = EW/TEH x 100. Data were analyzed using descriptive statistics and independent sample t-tests. Results: The mean values for TEH, EW, LH, and LW increased with increasing age for both the right and left ears. Male participants had significantly greater TEH and EW compared to females for both the right and left ears. There were significant differences in lobule height (right ear) and lobule index (right and left ear) between males and females, with males having slightly larger measurements than females. Conclusion: Our study provides valuable information on ear dimensions and anthropometry in a sample of Indian college students. The findings of our study are consistent with previous studies conducted worldwide, as well as in India. Our study highlights the importance of considering gender and age when investigating ear dimensions and anthropometry. Keywords: Ear dimensions, Anthropometry, Indian, College students.
Cross-Sectional Anthropometric Study of the External Ear
Journal of Forensic Sciences, 2007
This cross-sectional anthropometric study was aimed at estimating expansion of the external ear during adult life, in order to evaluate the extent to which anatomical features appearing in earprints may vary with time. A review of the literature was provided. Data extracted from photographed ears of 1353 subjects were analyzed. The effect of age on auricle length, earlobe length, and auricle width was explored using univariate analyses of variance. The regression coefficients of age on these dimensions were, respectively, 0.178, 0.115, and 0.073 mm/yr for males, and 0.162, 0.100, and 0.073 mm/year for females (p 5 0.000). Regression coefficients of age corrected for stature were assumed to be less accurate. Anthelix prominence and helix width were analyzed using data of 175 subjects, and appeared unaffected by age. As lobe expansion appeared to exceed the estimated cartilage expansion, it was assumed that particularly the imprint of the lobe would be less stable with time.
A morphometric study of the external ears at Benin City
Background: The study was carried out to establish the normal auricular dimensions in Nigerians resident in Benin City. Methodology: A cross sectional study of both ears of 1462 Nigerian school children and young adults was carried out. Measurements of the facial height, ear height, ear width, lobule type, lobule height and lobule width were taken. Record was also made of the age, sex and ethnicity of both parents. Results: The mean (S.D.) facial height in the entire cohort was 180 (20.8) mm. The ear height, ear width, lobule height and lobule width were 55.6 (6.0) mm., 32.4 (4.5) mm., 14.0 (3.8) mm., 16.0 (4.8) mm. and 55.6 (6.0) mm., 32.0 (4.5) mm., 14.0 (3.8) mm., 16.0 (4.8) mm. for the right and left ears respectively. The male facial height was longer than the females’. There were no significant differences in ear parameters for the right and left except for the ear width. Significant sex variations were found among sexes ( p<0.05). When the study population was stratified i...
