Proper anesthesia and knowledge of the anatomical location of ilioinguinal nerve is important during hernia repair and other surgical procedures. Surgical complications have also implicated this nerve, emphasizing the importance of the development of a clear topographical map for use in its identification. The aim of this study was to explore anatomical variations in the ilioinguinal nerve and relate this information to clinical situations. The study was conducted in Khartoum state – Sudan on 77 formalin embalmed cadavers which were dissected bilaterally to expose ilioinguinal by transperitoneal approach, in Sudanese male cadavers, age ranging from 24-56yaers. Regarding root origin, the study revealed that the Ilioinguinal nerve has varied root origin from L1, L1-3 and L3 in 151 (98.1%), 2 (1.3%) and 1 (0.6%) dissected cadaver respectively. In the right side 3 cadavers showed that aberrantly rise from either L3 or L1-3 root of origin, whereas, this aberrant observation was not seen in the left side. Of note, in the left side the Ilioinguinal nerve was originated solely from the first lumbar spinal segment. The result of this study will help the surgeons to avoid iatrogenic nerve injury as well as to assess them during lumber plexus block.
