When making a "smile" expression, facial muscles touch each other, resulting in a depression called "dimple". Not everyone has dimples, but people who have dimples also have different shapes and heights.

Under subdivision, dimples are located about 2-2.7 cm above the corners of the mouth, and there are three kinds of dimples: round, oval and fissure. Generally, dimples are the most obvious when you laugh. The formation of dimples is mainly genetic. It can also be obtained through plastic surgery.

Method of forming dents:

1, suture method: the suture method of forming dimples, also known as suture method, directly connects muscles and dermis at the position of buccal fossa with silk thread to form dimples. The suture method is simple and easy, and there is no surgical incision, but the effect is uncertain, and the dimple after molding is easy to disappear.

2. Intraoral incision: make an 8mm transverse incision at the oral mucosa corresponding to the oral fixation point, separate the small incision to expose the buccal muscle fiber, clip out and cut off the muscle fiber, and sew the buccal mucosa in the oral cavity with the subcutaneous dermis at the buccal fixation point to see the appearance of the artificial dimple.
