Abstract

Microgenia is that the mental protuberance is small state because of symphysis did not developed properly while occlusion and size of mandible are normal. One or two-step sliding advancement genioplasty is mainly performed to make good aesthetic harmony with face, but in slight or moderate degree of microgenia patients who do not want general anesthesia or osteotomy, the multiporous high-density polyethylene(Medpor(R)) can be used. It is easy to carve and bend, and has a variety of size and shape to fit the contour of the chin anatomy. Under the local anesthesia. a vertical incision which can preserve mentalis muscle is made about 2 cm at inferior labial sulcus along inferior frenulum in the jaw midline. Subperiosteal dissection is performed to make a pocket. Seperated Medpor(R)s are inserted in each side and reassembled into one in the midline. To minimize bone erosion, implant has to be placed on the inferior side of mandible edge and fixed with screw. Bandage compression was applied for 3 days and antibiotics was treated for 7 days postoperatively. This technique has a small incision, easy procedure and faster recovery. During the follow-up period, there were no specific complications and patients were all satisfied to their result.
