Is it possible to make a liposuction around the deltoid muscle around the shoulders?

Thanks for your question, Sauvage123.
It’s possible to do a liposuction around your deltoid muscle if you have stubborn fat deposits there. As for sagging skin, it’s hard to say because it depends on several factors, like your age, weight, and skin elasticity.
To get a more personalized recommendation, I suggest that you personally consult a reputable and board-certified plastic surgeon.
Good luck!
