A Servey on Different Types of Ear Lobule in a Kerman Population in 2015

Changes and deformities of the auricle are very important in order to understand some congenital diseases as well as beauty aspect. Lobule is one of the most important parts of the auricle which has most changes in comparison to other parts. The aim of this study was to evaluate the different types of ear lobule in a Kerman population.
In this cross-sectional study, 400 Kermanian natives (200 males, 200 females, aged 20 to 30) were selected using cluster random sampling method and anthropometric features of lobule (attached or free) in these subjects were assessed. Also, ear length and width were measured using calipers. Data were analyzed using independent t -test, paired t -test, and chi-square test.
The results showed that the frequencies of free and attached lobule in males were 80% (160 persons) and 20% (40 persons) and in females 89.5% (179 persons) and 10.5% (21 persons), respectively. The means and standard deviations of ear length in males and females were 59.86±3.06 and 60.12±3.37 mm, respectively (P=0.089). Also, the means and standard deviations of ear width in females and males were 31.36±3.61 and 30.71±3.94 mm, respectively (P=0.023).
In Kermanian population frequency of free lobule is more common than attached lobule. Also, the significant difference between males and females in the width of auricle can be used in forensic medicine investigations.
