Mandible angle plastic: farewell to square face malformation

The easterners consider small faces and sharp chins pretty. Nowadays when thinning faces get popular, beauties with small faces become fashionable. In many national surgeries of artificial beauties, the would-be beauties have one common surgery to be done, that is the facial contour plastic surgery. Why? Because the facial contour beauty is the first condition and most outstanding symbol of one’s physical beauty. This surgery makes sense to whether one could be a beauty.

What is the square face? (mandible angle hypertrophy)

A square face refers to the swelling and protruding part known as Sai under the both ears. When seen from the front, the contour of both facial sides goes down vertically, intersecting the lower contour nearly in a right angle and making the lower one third of the face broad and wide. This is so called square face or mandible angle hypertrophy. In the respect of anatomization, it is due to the over growth of the mandible angle (part of mandible angle) bones or the over hypertrophy of the gnawing muscle, or both. The mandible angle hypertrophy usually happens on both sides and one side hypertrophy cases are many as well. It is always related with the overtaking socks and chewing gums( or betelnuts) in the juvenescent phase. And it can also be caused by grinding teeth at night. These all make muscle groop(muscles,) exercise too much and thus stimulate the muscle and skeleton of the mandible angle area to grow and finally form the square face disfigurement.


How to change square face into water melon face?

Before ascertaining the therapy for square face, it is necessary to know the specific reasons of how square faces come into being. And according to these reasons the cosmetic surgery can be devised. When performing this surgery, the doctor shall distinguish the mandible angle hypertrophy from the rib gland tumor and cyst. Through the X ray picture, the doctor makes out the reason of hypertrophy and takes pertinent measures to exscind the protruding part according to specific situations and finally turn the square face into the water melon face. If the mandible angle bones grow excessively, the surgery is to cut the bones. If the masseter grow too large, the surgery is to cut the part of masseter or inject bacilli toxin to cause masseter amyotrophia.

How to perform the mandible angle plastic surgery?

There are four kinds of plastic surgery cuts, external mouth cut, internal mouth cut, integrated cut of internal and external mouth and behind-ear cut. At present, the first two kinds are mostly adopted to rectify the mandible angle hypertrophy. The hospital uses the international new technique instead of the traditional facial plastic method, adopting micro cut access to perform the operation, which greatly enhances the operation efficiency, lessens the operation time and reduces the operation wound. The cut scars also appear invisible, attracting more people coming to pursue beauty.

Angle hypertrophy micro cut is comparative with the traditional mandible angle hypertrophy rectification. Let us take the micro cut mandible rectification for example. The rectification operation lasts for 3 hours before with 3-4 centimeters long cut. The patient needs entire anaesthesia and shall stay in hospital for a week. It takes a long time to recover due to the great operation wound. Furthermore the operation risk is great, it is impossible for one lack of bravery to accept it. But the present micro cut method with advanced facilities and prominently skilled doctor reduced the operation time from 3 hours to half an hour and the cut from 3-4 centimeters long to less than 1 centimeter. The patient feels no pain during the operation and just needs to stay in hospital for one week. And the detumescence can be resumed one to two weeks after the operation. Some patients from outside Shanghai fly to hospital in the morning, get operated on in the afternoon and leave next day. The operation is very safe and convenient.

What anaesthesia will be used for the operation? Will entire anaesthesia do harm to the body?

The operation is usually conducted in the situation of entire anaesthesia. When the patient wakes up, the operation is accomplished. Many people are doubtful about the entire anaesthesia, afraid that it is harmful to the brain. In fact it is fairly secure at present, less harmful to the health than excessive drinking. In some western developed countries, most operations are completed on the occasion of entire anaesthesia. The external mouth cut operation can be conducted in the situation of partial anaesthesia.

What preparations shall be taken before the operation?

The patient shall be healthy without tissueic pathological changes of important viscera such as heart disease, hepatitis, nephritis and pneumonia. Neither can he has mouth infection resources such as decayed tooth, and teeth abscess. The female patient shall avoid the menses.The patient shall take blood and urinate routine check as well as cardiogram routine check. The check of X ray pictures of the mandible flexura break and the mandible side position shall be taken for some special patients. The cigarette addicts shall stop smoking before the operation. The aspirin, prophylactic and some anti-inflammation medicine can increase the haemorrhage and thus shall be stopped.


What shall be paid attention to after the operation?

The patient must not take anything in two days after the operation to prevent infection, who shall rely on transfusion to maintain physical demands. After 48 hours he can take fluid food such as milk, fruit juice and broth. 72 hours later he can take semi-fluid food such as yogurt, thick egg soup, flour mash and porridge. And gradually he can resume normal biting and supping. And in a month he shall not take rather hard food and assume great laughter. The patient doesn’t need to worry about the discomfort in the operation and can avoid the aches after the operation. At present the advanced micro pump pain-killing facility is provided in the hospital which can supply continuous pain-killer in the tiny dose in the 48 hours to make the patient recover in a pleasant mood. Generally the patient is supposed to stay in hospital for one or two days for observation and work normally after 10 days.When he leaves hospital, only 80%-90% of the operation effect can be acquired mainly due to the incomplete detumescent of the parenchyma. Sendondly, the large masseterhas just been cut

About the operation risks

Because there spread rich nerves and blood vessels under the cheek and the mandible and it’s joint are responsible for the function of gnawing and speaking, the mandible plastic surgery is the one of the most complicated operations in the cosmetic surgeries. Any fault can make inexpiable consequences. On the occasion when domestic cosmetic surgery market is lack of regular administration and doctors’ qualifications vary largely, the person who asks for the plastic surgery shall be cautious to choose the proper hospital and doctor.
