A pear-shaped face, as the name suggests, is close to the shape of a pear, showing a square triangle with a small top and a large bottom. Generally, there are three major tissues affecting the lower 1/3 of the face: jawbone, biting muscle, and fat, and any of them are wide or thick, which may cause pear-shaped face. Therefore, pear-shaped face want to quickly thin face must be directed at the cause of treatment. Specifically as follows: 1, if the jaw angle is thick and hypertrophied, you can undergo jaw angle grinding surgery. The surgery can choose intraoral incision to avoid external skin scarring, and at the same time, it can excise all the redundant inner and outer layers of the mandible, and polish the edge of the remaining outer plate of the mandible to make it thinner, so as to completely solve the facial contour problems caused by the wide mandible; 2, if it is a hypertrophy of the biting muscle, it can be used to use Botulinum Toxin A to slim down the face. The dosage of injection is decided according to each patient’s biting muscle, usually 3-5 points are injected in each side of biting muscle. Generally 7-10 days after injection, the effect will start, with the metabolism of the drug, generally in about 4 months the biting muscle began to gradually recover, about half a year to a year’s time to recover; 3, if it is a problem of fat, you can carry out facial fat suction as well as intra-oral approach for buccal fat pad removal. Of course, many patients’ pear-shaped face is not caused by a single reason, and then it is necessary to apply the above methods for personalized treatment.
