Virtual changes of the shape of the lips

Many of the unsatisfactory results in cosmetic surgery are due not to the t echnique employed itself but to the virtual changes that our work has impos ed in other areas. These changes are especially evident in the face, due to the small dimensions of its organs. The surgeon should do a thorough evalu ation of the area to be treated prior to the surgery and make her/him notic e not only the usual existing asymmetries, but also the modifications which probably will be noticed in the neighboring parts after surgery, to avoid later problems. The surgeon will discover then the many irregularities a pa tient may have, which have not been noticed by the patient before. These, i f not detected in time, are weapons that may act as a boomerang against the surgeon later.
