Substitute correction for low or collapsed cheekbones

Low-level or collapsed surrogate surgery for the treatment of humeral arch fractures. Local depression caused by old humeral arch fractures is often an important part of advanced treatment, with the aim of improving shape, raising condyles and restoring height. Therefore, from the aesthetic point of view, it is best to achieve the purpose of high condyle without increasing facial scars, but this method is not suitable for use in patients with limited mouth opening. In order to achieve the above purposes, the incision is usually selected in the hairline or in the inferior temporal margin, and the incision can also be made in the local original scar. Due to the difficulty of resetting or the possibility of greater damage, an appropriate material can be used for the ankle height. The choice of cushioning material may vary from case to case or from surgeon's experience, with autologous bone, allogeneic bone and various heterogeneous planting materials. At present, there are many autologous bone grafts, and the skull flap is often used. The outer plate can be taken, and two or three outer plates overlap and increase the condyle. Because it is close to the material, it does not increase the incision, and can be transferred with pedicles. It is an ideal material to be taken. Among the heterogeneous materials, a biomaterial, a composite material of hydroxyapatite and aluminum oxide, which utilizes the strength of aluminum oxide and the biological activity of hydroxyapatite, can produce the advantage of bone healing. Achieve the purpose of increased conflict. In addition, there are silica gel blocks in non-biological materials, which are pre-formed into a certain shape and surgically implanted. Treatment of diseases: humeral arch fracture Indication Low-level or collapsed surrogate surgery for the treatment of humeral arch fractures. Local depression caused by old humeral arch fractures is often an important part of advanced treatment. Surgical procedure 1. Incision 3D incision in the hairline before the incision, cut the skin, subcutaneous tissue and superficial temporal layer of the fascia, and use a sharp separator to separate the humerus from the fascia and the diaphragm. Part. Free to the periphery to form a bag shape. 2. Implant a pre-formed substitute to restore the shape of the cheekbones. If the implant is too high, it can be trimmed to fullness. 3. Suture the wound and compress the dressing. complication 1. Hemostasis is not complete, causing local hematoma. 2. The wound is secondary to infection. 3. Implanted substitutes shift, affecting shape recovery.
