Introduction to Nanjing mandibular angle plastic surgery: Mandibular retrognathism, also known as micrognathia, usually results from congenital growth and development, leading to a short mandibular body, mandibular retrognathism, and a small or even non-existent chin, causing facial disproportion and loss of facial contour beauty. Aestheticians believe that the straight line connecting the nasal tip, the red edge of the lower lip, and the submental point is the beauty line. If the lower lip reaches or is 1-2mm away from the beauty line, it generates an aesthetic feeling; otherwise, it is considered unattractive. Some people have a protruding nasal tip and lips while having a relatively short chin, which can be regarded as relative mandibular retrognathism. If the chin is too short and there is a desire to change it, cosmetic plastic surgery can be used to lengthen and reshape the chin. Chin implants such as medical-grade solid silicone or Gore-Tex chin implants can be used for correction, or autologous bone filling can improve appearance.
Additionally, the lower part of the mandible in the chin area can be cut and pulled forward to increase the projection of the chin. The chin augmentation material needs to be sculpted into an appropriate shape, and the surgery is generally performed under local anesthesia through an intraoral approach. Through an incision in the oral mucosa, a cavity of appropriate size is separated, and the chin augmentation material is filled into the chin area to achieve the effect of lengthening the jaw and reshaping for a fuller chin.
The modified intraoral small incision chin augmentation technique used by Korean experts has characteristics such as small incisions and accurate implant positioning, providing satisfactory results for improving the chin profile. After chin augmentation, pressure dressing is required to prevent the movement or deviation of the chin augmentation block. Antibiotics and oral care are administered to prevent infection, all of which contribute to achieving a fuller chin.
The chin is the third factor influencing facial contours. A standard jaw should generally meet two points: one, the distance from the base of the nasal columella to the tip of the jaw is one-third of the entire facial length; otherwise, the face appears shorter. Two, the nasal tip, the prominent point of the lower lip, and the prominent point of the jaw lie on a straight line; otherwise, it looks like a piece is missing, commonly known as "bird beak." All these can be corrected through surgery.
People with mandibular retrognathism (micrognathia) but normal chewing function are most suitable for this type of jaw correction surgery. Jaw correction surgeries basically all use the intraoral approach method, with all surgical operations performed inside the mouth, leaving no scars on the face.
Artificial mandibular implantation is suitable for people with mandibular retrognathism or micrognathia and is also the most common surgical method. Patients with mandibular retrognathism are mostly mild to moderate cases, and the placement of artificial mandibular implants is more natural, with high satisfaction and fewer complications.
Mandibular bone reshaping surgery is suitable for those with too short mandibular bones, severe retrognathism, protrusion, or mandibular bone deviation. If the patient's mandibular deformity causes facial deformity, there are various correction methods, and the appropriate surgical plan must be chosen based on specific conditions.
Liposuction is suitable for those whose mandibular bone edges are submerged by fat, i.e., double chins, which are very common among middle-aged and elderly people.
