Deviated mouth correction surgery

Ankle angle deviation refers to a mouth shift (upward or downward shift) in which the red lips are intact and the thickness of the soft tissue of the lips is substantially normal. The main cause of the skew of the mouth is due to the scar of the local skin and the superficial defect of the subcutaneous tissue, which is usually repaired by Z-cross flap. Curing disease: Indication 1. Oral angle displacement deformity caused by skin and subcutaneous tissue defects in the mouth area. 2. The scar in the mouth area causes a skewed deformity, which is feasible after the scar is softened. Contraindications In the case of local infection, it is not suitable for surgical correction. The deformity formed by the recent scar is not suitable for surgery in the short term, and it takes 6 months to operate. Preoperative preparation 1. Keep the local skin clean, clean and free of inflammation. If there is inflammation, surgery should be performed 4 weeks after the inflammation is cured. 2. Accurately measure the vertical distance from the horizontal connection of the pupils on both sides to the width of the sides of the mouth, determine the position of the affected side, and develop a surgical plan. Surgical procedure 1. According to the pre-operative measurement data, design and draw the position of the affected side of the mouth, design the Z-shaped cross flap. 2. Cut the skin and subcutaneous tissue according to the incision line and turn up the dual triangle flap. 3. Transfer the Z-shaped flap to restore the normal position of the affected side. 4. After the flap is transferred, the suture is closed with a 3-0 or 5-0 silk thread to close the wound. 5. Use a butterfly tape for local tension and compression dressing. complication Wound infection and partial sutures are loose, and the wound is split.
