I have done a lower jaw surgery for a class two malocclusion overbite, results: 1) numbness in my jaw and a discomfort feeling 2) skin redness in the jaw area and face, never had this before surgery 3) Jaw surgery cause ASSYMETRICAL JAW line and when I told the surgeon that, he claimed I had it before surgery, which I didn’t, look at my before pictures 4) surgery increased my lisp/ saliva production and its harder for me to say some words 5) my mouth most of the time is slightly open 6) surgeon mentioned that there is only 4% numbness, and I realized after connecting with people who’ve done surgery that 99% got numbness. 7) oral intimate is painful Bottom line don’t believe this surgery doesn’t have side effects, enjoy the feeling of your lips and the comfort of un-paralyzed half face.
