Morphological variations of the vermiform appendix in Iranian cadavers: a study from developing countries.

Area of Science:

• Anatomy
• Anthropology
• Forensic Medicine

Background:

• The vermiform appendix, rich in lymphoid follicles, lacks extensive data in the Iranian population.
• Understanding appendix morphology is vital for clinical and anthropological applications.

Purpose of the Study:

• To establish standard data on normal vermiform appendix size in the Iranian population.
• To investigate morphologic variations of the appendix.

Main Methods:

• A cross-sectional study of 693 Iranian cadavers (mean age 40.46 years) was conducted.
• Appendix length, diameter, and weight were measured; position was recorded.
• Statistical analysis was performed using SPSS software.

Main Results:

• Mean appendix length was 8.52 ± 2.99 cm, diameter 12.17 ± 4.53 mm, and weight 6.43 ± 3.26 g.
• The retrocaecal position was most common (71.7%).
• Significant correlations existed between demographic data and appendix size, with notable sex-based differences in diameter and index.

Conclusions:

• This study provides essential morphologic data on the vermiform appendix for the Iranian population.
• Findings are valuable for clinicians and anthropologists, aiding in understanding anatomical variations.
