Abstract

Background: The vermiform appendix is a worm-like tube containing a large amount of lymphoid follicles. In our knowledge, there is a little standard data about the vermiform appendix in Iranian population. Therefore, the objective of this study was to investigate the normal appendix size in Iranian cadavers.

Materials and methods: A cross-sectional study was undertaken between June 2014 and July 2015, in the autopsy laboratory, Legal Medicine Organisation, Razavi Khorasan province, Iran. A total of 693 cadavers with the mean age of 40.46 ± 20.99 years were divided into 10 groups. After writing down position of the appendix, the length, diameter and weight of the appendix were measured. Statistical analysis was performed using SPSS software.

Results: The mean values of the demographic characteristics included — age: 40.46 ± 20.99 years; weight: 63.47 ± 17.84 kg; height: 159.95 ± 28.23 cm. The mean values of the appendix length, diameter, weight and index in the cadavers were 8.52 ± 2.99 cm, 12.17 ± 4.53 mm, 6.43 ± 3.26 g and 0.013 ± 0.01, respectively. The most common position of the appendix was retrocaecal in 71.7% of cases. Significant correlations were evident between the value of demographic data and appendix size (p < 0.05). The diameter (p = 0.002) and index of the appendix (p = 0.003) showed significant difference between males and females.

Conclusions: Having standard data on the vermiform appendix is useful for clinicians as well as anthropologists. The findings of the present study can provide information about morphologic variations of the appendix in Iranian population.
