Sausage mouth usually refers to a mouth as thick as sausage, also called sausage mouth. Sausage mouth is mainly caused by the thickening of lips. So it is mainly through an operation called thick lips and thin lips. Thinning a thick lip means cutting a part of the lip from the red lip, generally making a wedge-shaped incision, and then sewing it up after cutting to make the lip look thinner, so as to achieve the purpose of thinning. This operation is performed occasionally in clinic, because most girls like to pout, and the meat is pursed. When doing thick lip thinning surgery, it is more common in male thick lips, and thick lip thinning can be done.
