Under most circumstances, mesh does not involve implanting metal such as staples. Just like a microwave, would not want to treat over metal implants. However, typically metal not used in hernia repair.
There are a bunch of treatment options out there but the Jowls are a hard place to get a good treatment. For an easy and noninvasive treatment look into the INMODE Evoke, no downtime and a quick and easy process.
Noninvasive devices, kybella, even liposuction dont often work for lipomas. most need to be removed surgically. I suggest you see an expert. Best, Dr. Emer.
