Mandibular reduction involves reducing excess bone in the angle and back of the lower jaw that makes the lower face look too wide and square. This condition is common in Oriental patients.
Dr Huang uses advanced Korean surgical techniques, instruments and equipment for this procedure. It is minimally invasive and requires only small incisions on the inside the lower cheek, with no external incisions. The entire procedure is therefore completed intraorally (i.e. through the mouth).
Small incisions are made on the inside of the lower cheeks. The outer surface of the mandible on each side of the face is exposed. A specially designed powered rasp is inserted and used to file away excess bone in the back and angle of the mandible until the lower face is judged to have been sufficiently narrowed. A fine drainage tube is inserted into the wound of each side of the lower cheek to allow residual bleeding to be evacuated after the surgery. The drainage tubes are connected to small plastic collection bulbs that are taped to the side of the neck for convenience. The operation takes about two hours and it is usually completed under general anesthesia as a day surgery procedure.
Postoperative pain is mild and well controlled with oral pain medication. There will be moderate facial swelling, but usually without bruising. A compression garment for the face is worn for the first one week. The surgical drains are removed after 24 to 48 hours during the first check up. No stitch removal is required since the sutures inside the mouth will dissolve on their own. During the first one to two days, a liquid diet is necessary because of the presence of the drain in the mouth. Thereafter, soft food is allowed until the end of the first week, when a normal is resumed. During the first one to two weeks, opening the mouth fully may be difficult due to swelling and stiffness of the cheek tissues, but this usually returns to normal by the end of the first month. The downtime is usually about two weeks due to facial swelling. Exercise may be resumed after one month.
This minimally invasive technique has a high level of safety when correctly performed. Blood loss is minimal and the risk of infection is very low. The risk of damaging vital structures in the cheeks, such as nerves is also very low.
