ABSTRACT

Background: An ilioinguinal nerve branches off the lumbar plexus' branches. Due to its anatomic variations, it can contribute to neuropathies accompanying lower abdominal procedures. Aim: The study's objective was to illustrate the double ilioinguinal nerve variation through the dissection of human cadavers. Material and methods: Following clearance from Alzaiem Alazhari University's ethics committee, a cross-sectional analysis of corpses conserved in formalin was conducted (January 2021–May 2022). Using the internal and external inguinal rings as well as established bone markers, the IINs were exposed and mapped on both sides during the cadaveric dissection from their lateral appearance on the anterior abdominal wall to their midline ending. SPSS edition 21.0 had being utilized to manage the gathered information. Results: In 77 cadavers, ilioinguinal nerves were recognized bilaterally. All IINs originated from L1 on the left side, while on the right 3 IINs abnormally originated from L3 or L1-3. The difference was not significant (P=0.22). Double ilioinguinal nerve was observed in 8.4%. This variability had been noticed on the left and right sides in 8 (5.2%) and 5 (3.2%) corpses, respectively (P=0.56). Conclusion: It is essential to be aware of the double ilioinguinal nerve variant to prevent its damage during lower abdominal procedures such as inguinal hernia and low transverse incisions for orthopedics, gynecology and anesthetic procedures.
