“…Ear length was proven to have lowest level of fluctuating asymmetry among other parts of body (Zadzinska 2007) [25]. The correlation coefficient for bilateral symmetry for ear length in present study was as high as previous studies such as Alexander., et al (2010) and Liu (2008) [5,24]. Nevertheless, bilateral comparison could still be done with qualitative methods based on ear structures without considering symmetry level of ear biometrics (Singh & Purkait 2009) [2].…”

“…There might be some exceptions that caused by different population, gender, sample size and range of ages used in different studies. In fact, pediatric more regularly having asymmetry in ear biometrics if compared to adulthood while male more often to show asymmetry in ear biometrics if compared to female (Alexander., et al 2010;Wang., et al 2010) [24,13].…”

The objective of this study was to study ear biometric for identification purpose among young adults in Malaysia. A total of 148 subjects (74 males and 74 females) ranging in age from 18 to 25 years were taken from Campus Kuala Lumpur of National University of Malaysia (UKMKKL). A total of twelve biometrics based on Iannarelli's method as well as ear length and ear width were used as measurements. Statistical analysis indicated that left and right ears had no significant difference (p > 0.05). Gender difference was found to be highly significant for nine out of fourteen ear biometrics (p < 0.05). However, there were only five out of fourteen ear biometrics had significant difference between Chinese and Malays (p < 0.05). Statistical analysis had also indicated that differences among ages for each ear biometrics were insignificant and no clear correlation between ear biometrics and ages was obtained (p > 0.05). Formulae for gender and race estimation were obtained by using Classification and Regression (C & R) Tree. Formulae of ear length had the highest accuracy (78.7%) for gender estimation.

“…All the observations were done on the right ear as the literature mentions a good symmetry and no statistically significant difference in right and left ears. 6,7 Total 7 morphometric characteristics were includedpinna length, pinna width, attachment/root of ear, pinna projection, ear lobe length, ear lobe width, distance between tragus and antitragus (intertragic distance). The measurements were recorded in centimetres and data was tabulated and analyzed statistically.…”

Background: Individual differences in morphometric and somatoscopic observations of pinna of ear were studied to explore the potential of pinna of ear as a biometric tool.Methods: Morphometric and somatoscopic data of right ear of 350 Indian individuals (Age: 17-25 years) was collected. Measurements of pinna length, pinna width, pinna root, pinna projection, intertragic distance, ear lobe length, and ear lobe width were taken. Observations were done for presence or absence of Darwin tubercle, flat or rolled helix, and attached or free ear lobe. Probability statistics was extrapolated to assess the variations in ear pinna characters.Results: All measurements showed a wide range. There was statistically significant difference between male and female pinna measurements. The somatoscopic observations showed 82.9% individuals with presence of Darwin tubercle, 99.1% with rolled helix, and 65.4% with free ear lobes. On the basis of extrapolation of ten different morphometric and somatoscopic parameters, the statistics showed the probability of any two individuals having exactly same observations to be 0.0008%.Conclusions: The wide range of measurements in the present study suggested a high possibility of variations amongst the population. If all the parameters including both morphometric and somatoscopic, are taken into consideration, the pinna of ear of each individual is a very distinctive structure, which makes it a potential biometric identifier and with the use of proper technologies, it will be a widely used biometric tool in the future.

“…Em um estudo que analisou 420 voluntários, considerando aspectos como idade, sexo e origem étnica, observaram um incremento significativo de todas as dimensões lineares do pavilhão auricular externo até os 74 anos de idade. O estudo também apontou que, além do crescimento, houve mudança no ângulo do eixo longitudinal dessa estrutura anatômica 19 . Achados semelhantes foram constatados no trabalho de Sforza e Grandi, que ainda apontou um padrão de crescimento diferente entre homens e mulheres, inclusive em um grupo com idade entre 18 e 30 anos de idade, idade em que o crescimento estatural não é mais esperado, para a maioria dos indivíduos 18 .…”

Resumo.A identificação humana é o procedimento por meio do qual uma pessoa à diferenciada de outra em função de suas características únicas (físicas, psíquicas, funcionais e civis). A crescente demanda dos serviços de identificação post mortem associada ao crescimento da criminalidade em nosso país, sobretudo dos números absolutos e relativos dos crimes contra a vida, coincidiu com a utilização de métodos que
