For a modified radical neck dissection, most lymph nodes on one side of the neck between the jaw bone and collarbone are taken out, as well as some muscle and nerve tissue.
In an extreme neck dissection, nearly all nodes on one side, in addition to much more veins, nerves, and muscles are removed.
The most typical negative effects of any neck dissection are pins and needles of the ear, weak point when raising the arm above the head, and weak point of the lower lip.
These adverse effects are caused when nerves that provide these locations are harmed during the operation.
After a selective neck dissection, the nerve may only be injured and can heal in time.
Nerves heal slowly, but in this case, the weakness of the shoulder and lower lip may disappear after a couple of months.
The weakness will be long-term, if a nerve is eliminated as part of a radical neck dissection or due to the fact that there is a tumor involved.
After any neck dissection procedure, physical therapy can help enhance neck and shoulder motion.
Cancers of the nasopharynx often infect the lymph nodes in the neck.
These cancers typically respond well to radiation treatment (and often chemotherapy). However, if some cancer remains after these treatments, an operation called a neck dissection may be needed to get rid of these lymph nodes. Lymph nodes in the neck may also be taken out to see if there are cancer cells in them.
A selective or partial neck dissection eliminates only lymph nodes that are closest to the tumor and with biggest probability of cancer spread.
A modified radical neck dissection removes lymph nodes on one side of the neck between the jaw bone and collarbone, as well as some muscle and nerve tissue. The main nerve to the shoulder muscle is generally conserved.
A radical or detailed neck dissection gets rid of nearly all lymph nodes on one side in addition to a lot more muscles, veins, and nerves.
