Abstract

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.
