Abstract
The technical problem to be solved by the present invention is to design a cosmetic surgical method for presenting a deeper or longer philtrum at the lip by adjusting the muscle flaps at the lips and nose. The theoretical basis of this surgical method is a 'theory of labionasal muscle tension thread group' summarized from a series of studies with respect to anatomy, biomechanics and clinical surgical verification. According to this theory, the labionasal muscle tension structure is reconstructed by surgical adjustment of the position and direction of the muscle flaps, so as to produce an effect of changing the profile of the 'philtrum' and to improve or remodel the “philtrum” as an aesthetic labial structure.
