The neck is an incredible and complex nexus between the head and the body. The neurovascular structures are intricate but when handled with respect, they are robust, and where oncologically sound should be preserved.
Neck dissection is a routine part of head and neck cancer management. When performing a neck dissection, node-bearing tissue is removed to stage a patient for regional spread of cancer. Depending on the final histology and whether cancer is identified within any lymph nodes, this can influence treatment algorithms such as whether the patient would require adjuvant radiotherapy and possibly chemotherapy.
Elective neck dissection has been shown to provide a survival benefit of up to 15%.
Ultimately, the goal of surgery is to provide the patient with a chance of cure, improve survival but also to preserve function and quality of life.
As you can see here, all the important structures are preserved. Ansa cervicalis contributes to swallow function. The accessory nerve contributes to shoulder movement. The facial nerve (not annotated) provides facial movement. The hypoglossal nerve (not annotated) innervates the tongue. The neck muscles are kept intact to maintain bulk, symmetry and function. The carotid artery (deep to IJV) supplies the face and majority of the cerebral flow to the brain.
Here is the left neck after a I-IV neck dissection in the management of a left lateral tongue SCC.
