What is a key characteristic of the great auricular nerve as a graft option?
What is a key characteristic of the great auricular nerve as a graft option?
- It may not be available due to oncologic resection. (correct)
- It can provide up to 35 cm of graft length.
- It is most effective when harvested endoscopically.
- It requires multiple large incisions for harvesting.
Which of the following represents an advantage of using the sural nerve for grafting?
Which of the following represents an advantage of using the sural nerve for grafting?
- It is easily harvested during neck dissection.
- It is a motor nerve graft that guarantees superior outcomes.
- It requires no incisions for harvesting.
- It can provide grafts of up to 35 cm in length. (correct)
What is a major disadvantage of harvesting the sural nerve for grafting?
What is a major disadvantage of harvesting the sural nerve for grafting?
- It may lead to extensive scar formation at the harvest site. (correct)
- It can only be used for sensory nerve grafts.
- It can only provide a short graft length.
- It is difficult to access without incisions.

What is the Great Auricular Nerve?
What is the Great Auricular Nerve?
A nerve found in the neck used for interposition nerve grafting. It provides 7-10cm of length & is harvested during neck dissections.
What is the Sural Nerve?
What is the Sural Nerve?
A nerve found in the leg used for nerve grafting. It provides up to 35cm of length, but harvesting from the leg can create scarring.
What is Endoscopic Nerve Harvesting?
What is Endoscopic Nerve Harvesting?
A grafting technique using multiple small incisions to harvest a long nerve segment. Also known as endoscopic vein harvesting.

Study Notes
Donor Nerve Choice for Interposition Grafting
- Donor nerve selection depends on graft length needed, location, and harvest ease.
- The great auricular nerve provides 7-10cm and is easily harvested during neck dissection, but can be absent if sacrificed during oncologic resection.
- The sural nerve offers up to 35cm, and some evidence suggests a motor nerve graft might be better than a sensory one.
- Harvest techniques vary, from direct incision to less invasive methods using tendon strippers and passers.
- An endoscopic vein harvesting system allows harvesting long nerve segments via two small incisions but has disadvantages relating to distant harvest site and scar formation.
- Other options include the medial/lateral antebrachial cutaneous nerves or ansa hypoglossi.
