What nerve is cut during inguinal hernia repair?
The ilioinguinal nerve is a sensory nerve that innervates the skin over the groin region, the medial aspect of the thigh, the upper part of the scrotum and the penile root. It is normally encountered during open repair of inguinal hernia.
What causes ilioinguinal nerve entrapment?
The most common causes of compression of the ilioinguinal nerve are from trauma, especially blunt trauma to the nerve, as well as damage to the nerve during pelvic surgery. Ilioinguinal neuralgia will very rarely occur by itself.
What muscles does the ilioinguinal nerve innervate?
The function of the ilioinguinal nerve is to provide the sensory innervation to the skin of the upper anteromedial thigh and partially the external genitalia. Moreover, it provides motor innervation to the internal abdominal oblique and transversus abdominis muscles.
What type of nerve is ilioinguinal nerve?
mixed nerve
The ilioinguinal nerve is a mixed nerve originating from the anterior rami of T12 and L1 nerve roots. It emerges near the lateral border of the psoas major muscle and goes inferior through the anterior abdominal wall, being sub-peritoneal and anterior to the quadratus lumborum muscle until it reaches the iliac crest.
Does ilioinguinal nerve go through inguinal canal?
At the anterior end of the iliac crest the ilioinguinal nerve pierces the transversus abdominis and internal oblique muscles to enter the inguinal canal from the side, not through the deep ring.
Where does the ilioinguinal nerve originate?
The ilioinguinal nerve arises from the anterior ramus of the L1 nerve root from the lumbar plexus along with the iliohypogastric nerve.
How does the ilioinguinal nerve become superficial?
Then the ilioinguinal nerve goes through the transverse abdominis and the internal oblique muscles. It becomes superficial by passing through the superficial inguinal ring anterior to the spermatic cord.
Does planned excision of the ilioinguinal nerve prevent chronic pain after inguinal hernia repair?
Planned ilioinguinal nerve excision for prevention of chronic pain after inguinal hernia repair: a meta-analysis A planned resection of the ilioinguinal nerve at the time of inguinal hernia repair is associated with a decrease in the incidence of chronic postoperative pain.
How do you use the ilioinguinal nerve during dissection?
Ilioinguinal nerve and posterior abdominal wall in a cadaver: The course of the ilioinguinal nerve can help you during dissections. If you follow it laterally, you will reach the plane of dissection between the internal oblique and transversus abdominis muscles.
What is the function of ilioinguinal neuralgia?
In males, it also supplies sensory innervation to the anterior surface of the scrotum and root of the penis and in females, supplies sensory innervation to the labia majora and mons pubis. Male or female patients with ilioinguinal neuralgia may complain of pain, paresthesia and abnormal sensation in the area supplied by the nerve.
