Mandibular angle surgery is not a minor operation after all, and its possible complications include:

Mandibular fracture:

It has a lot to do with the doctor's operation, but the fragility of the patient's own bones will increase this risk and may require intermaxillary fixation or other timely treatment. Generally, there will be no serious sequelae, but the recovery time after operation will increase.

Nerve injury:

Common patients feel numbness of the lower lip after operation, which can last for half a year. Because pulling the mental nerve during the operation can be restored, don't worry.

Bleeding:

It is related to many factors, especially the rupture of facial artery, but timely treatment will not cause serious consequences after operation.

The mandibular angle is not smooth:

It has a lot to do with the way of osteotomy, and also has a certain relationship with the doctor's experience and aesthetics. The main reason is that the joint connection between the corner and the mandibular body is not good due to the straight osteotomy of the corner, which leads to the obvious protrusion of the mandibular body. Recurrence of mandibular angle: It has been reported that the bone in the corner has regenerated in the long term after operation, but it will not return to the preoperative state. We believe that this is often related to the incomplete washing of bone chips during surgery.

In addition, there are hematoma, infection, bilateral asymmetry and postoperative swelling.

What is the editor's square face of mandibular angle? It means that the part under the ears, commonly known as the cheek, is swollen and prominent. Seen from the front, the contours on both sides of the face are vertically downward and intersect with the lower contour at almost an angle, which makes the lower third of the face look very wide. This is the so-called square face, also known as mandibular angle hypertrophy. Anatomically speaking, it is mainly due to the overgrowth of bone or masseter muscle in mandibular angle (a part of mandibular angle), or both, which is called mandibular angle hypertrophy (or benign masseter muscle hypertrophy) in medicine. Maxillary angle hypertrophy is generally bilateral, and unilateral is not uncommon. It is often related to teenagers eating too many snacks and chewing gum (or betel nut) during their physical development, or it may be caused by grinding their teeth at night. These make the muscles of the maxilla (muscle, pterygoid muscle, etc. Excessive exercise stimulates the development of muscles and bones in the mandibular angle area, and finally presents "square face deformity".

The causes of mandibular angle hypertrophy editor

Maxillary angle hypertrophy is generally bilateral, and unilateral is not uncommon. How is mandibular angle hypertrophy formed? This is often related to teenagers eating too much snacks and chewing gum during their physical development, or it may be caused by grinding their teeth at night. These make the levator muscle (masseter muscle, medial pterygoid muscle, etc. Excessive exercise stimulates the development of muscles and bones in the mandibular angle area, and finally presents "square face deformity". Therefore, it can be considered that there are three reasons for mandibular angle hypertrophy.

1 mandibular angle bone hypertrophy

2. The masseter muscle overgrowth protrudes from both cheeks. Specific to each patient, the impact of the two reasons may be different, which may be that the bones are dominant or the muscles are dominant. But from the clinical experience, the two are often accompanied at the same time.

Some patients are caused by heredity, and their parents or relatives often have mandibular angle fat.

According to the shape of mandibular angle osteotomy hypertrophy, mandibular angle hypertrophy can be divided into the following three types: ① mandibular angle kyphosis, ② mandibular angle valgus and ③ mandibular angle valgus.

For orientals, the prominent mandibular angle is the main reason, including the mandibular angle is too backward, valgus or both, so the focus of treatment is mainly osteotomy and plastic surgery, and surgery is considered to be the first choice and the most effective method to treat mandibular angle hypertrophy at present.
