Most common nerve injured during hernia surgery:: (A) Ilioinguinal nerve, (B) Iliohypogastric nerve, (C) Genitofemoral nerve, (D) None of the above
Answer is A. External oblique aponeurosis is in close relation to ilioinguinal nerve & hence during operation for inguinal hernia, prevention of injury to ilioinguinal nerve to avoid later development of incisional hernia is very impoant. MC injured nerve in laparoscopic hernia repair: Lateral cutaneous nerve of thigh > Genitofemoral nerve (GFN) MC injured nerve in open hernia repair: Ilioinguinal nerve > IlioHypogastric nerve> Genital branch of GFNQ (GHI in reverse sequence)
