DETERMINATION OF THE USABILITY LIMITS OF AURICLE MORPHOLOGY FOR IDENTIFICATION

Öz

Objective: In the present study, it was aimed to evaluate the usability of morphological appearance of ears for positive and negative identification and to define the accuracy rates in ear identification using naked-eye detection by experienced volunteers. Methods: This study was performed in three stages: the gathering of 120 ear images (60 rights and 60 lefts) of 30 male and 30 female volunteers (between 18-26 ages), the observation by 20 volunteers experienced on the identification, and the statistical analysis with SPSS-11 Statistics Program. Results: The rates of correct responses were 86.5 % by proportional calculation and 99.73 % by probability calculation. Whilst the total rates of wrong responses were 12.5 % by proportional calculation and 0.25 % by probability calculation in male volunteers, they were 14.5 % by proportional calculation and 0.29 % by probability calculation in female volunteers (p>0.05) respectively. The total rates of wrong responses were more than twice in left ears than right ears. Conclusion: One-to-one matching of ear images with naked eyes can be used as a part of first elimination carried out by police officers in order to differentiate the perpetrator(s) of a crime among suspicious persons.
