What are the disadvantages of doing chin lipo under local anesthesia versus general?

The disadvantages of undergoing chin liposuction under general anesthesia are all the risks associated with general anesthesia like nausea, vomiting, weeks of generalized weakness as well as side effects to each one of the medications that are given to put someone to sleep.
When chin liposuction is performed under local anesthesia, all the risks of general anesthesia are avoided, thus making the procedure safer.
I routinely perform chin liposuction under local anesthesia with the patient wide awake and without any discomfort. As people can see on my Instagram stories and other social media posts, patients are not uncomfortable at all during the procedure under local anesthesia. They all unanimously say it does not hurt and that is way better than going to the doctor or undergoing any procedure under general anesthesia.
Chin liposuction under local anesthesia might be uncomfortable if the surgeon is not familiar or specialist on chin liposuction under local anesthesia.

I prefer to perform chin and jawline liposuction with local anesthesia and intravenous sedation. There is no need for general anesthesia. The disadvantage to using local anesthesia alone is that the initial injections of local anesthesia are painful to most patients. There is no nerve block in this area. Multiple injections are needed and this can be uncomfortable. Intravenous anesthesia eliminates this painful part of the procedure.

Dear TomH453,
generally speaking, local anesthesia can be used for chin liposuction however the results might not be as good as in case of general anesthesia. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.
