cicatricial lip valgus repair

After the lip is everted, the mouth can not be closed, the teeth are exposed, the mouth is overflowing, and the language is unclear. Such a deformity occurs when young, and can also affect the development of the mandible, so that the dentition is not neatly protruding forward. Therefore, depending on the condition of the scar, different surgical methods should be selected and repaired early. Treating diseases: lip disease Indication Lip valgus. Surgical procedure (a) vy forming Mild lip valgus, such as scars are not too hard, can be corrected with vy forming shape [Figure 1]. (two) skin repair For more severe scars, it is necessary to remove the scar and repair the skin. The ends of the incision should exceed the angle of the two sides. When separating, the scar should be completely removed to restore the lip to the original position, and then the medium or thick skin graft is used for repair [Fig. 2]. In the case of small mouth disease caused by scar, the sides should be symmetrical when the scar is removed, and the skin should be intact. There is more bleeding when separating the ankle, and careful attention should be paid to stop bleeding. In addition, there is less soft tissue here, and the force should not be too large when the pressure is applied, so as to avoid necrosis of the skin. (3) Local lateral shift flap repair For severe cases, a transverse arc-shaped incision can be made at the posterior part of the lower jaw. The two ends can reach the level of the mandibular angle. The stalk can be separated from the wound edge under the flap to form a pair of pedicle flaps, covering the lower lip wound, intermittent suture, lower The posterior wound was transplanted with a medium-thickness skin graft. After long-term valgus of the lower lip, due to the extension of the tissue, excessive lip tissue can be removed (including mucosa and muscle layer) after resection of the scar and reduction of the lip tissue. In the case of mild lip valgus, excessive mucosa may occur, and a transverse fusiform incision may be made to remove excess mucosa.
