Anthropometric Assessment of the Normal Adult Human Ear

International Journal of Anatomy and Research, 2017

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.

Introduction: The anthropometric Auricular measurements play a crucial role for reconstruction of absent, congenitally deformed or lost ears in cases of burns and accidents. Even essential for the effective designing of hearing aids ensuring their fit and function optimally.The present study aim is to determine the lengths and widths of auricle, lobule, concha,base of the ear and auricular, lobular and conceal indices.The objective of the study is to derive linear regression equations to estimate ear dimensions from side and gender. Methods: The present study was conducted on 240(120 male and 120 female) medical students with 18 to 25 years of age, Department of Anatomy, Gautam Buddha Chikitsa Mahavidyalaya, affiliated to Ras Bihari Bose Subharti university,Dehradun,India. Results: The findings of the present study confirmed prominent Sexual dimorphism in Auricular parameters along with bilateral symmetry in medical students of Dehradun. Conclusion: This study's uniqueness lies in its focus on deriving linear regression equations from side and gender, which is a departure from traditional studies that have relied on stature, age, and other anthropometric models.

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.

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.

Anthropometric measurements are considered to be a significant part while studying physical anthropology. This branch of physical anthropology involves measurements of the human beings in order to understand the physical variations occurred in humans on the basis of measurements of their morphological and physiological traits. External ear morphometric measurement is also an attribute of such anthropological studies which helps in determining the age, gender but also leads to successful identification of an individual. In the present study also, some physiognomic characteristics of external ear (shape of external ear and variation in ear lobe) along with the morphometric measurements and normal dimensions of total ear length and width (both right and left external ear) are taken from the population of India (North India) comprises of 100 individuals. The sampling procedure involves measurement from both males and females so as to make a comparison in such parameters which helps in determining the gender differences and thereby creates a data which leads to successful sexual dimorphism.

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.
