What to do if the jaw angle is asymmetrical?

The mandibular angle is one of the basic parts of people's image. Although the size and shape of the mandibular angle are not easy to attract people's attention, its position and effect on the image are uniquely important. By improving the shape of the mandibular angle, the purpose of improving the overall facial image can be well achieved. For example, what should we do if the mandibular angle is asymmetrical? Let's take a look at the explanation below, I hope everyone can understand it.

1. Bone grinding and mandibular angle reshaping. This surgery uses a grinding head to grind away the mandibular angle and the outer cortical bone of the mandibular body without removing the mandibular angle. Sometimes, a suitable grinding head can be used to grind away a small amount of the mandibular angle or slightly lift it up. The thickness of the bone removed is limited, only 5 to 6 mm at most, and the improvement effect is not obvious.

Advantages: simple and safe operation, less bleeding.

Disadvantages: Limited effect. Suitable for those who have a moderate mandibular angle and a wide mandibular angle when viewed from the front.

Mandibular angle reshaping with osteotomy

2. Osteotomy of mandibular angle or tangential osteotomy of mandibular angle. This surgery involves first drilling or notching with a ball drill, then removing the mandibular angle and outer plate with a thin bone knife, or using a reciprocating saw to directly cut off the outer plate of the mandible, retaining the cancellous bone and inner plate. Like the bone grinding method, the mandibular angle is not removed, so the original curvature of the mandible is retained, but the width of the mandibular angle is narrowed, and the improvement in the side view is not significant.

Advantages: It preserves the original mandibular curvature and is suitable for those who want to narrow the mandibular width while preserving the mandibular angle.

Disadvantages: The improvement is limited; since a bone knife is used for splitting during the operation, violent operation may cause fractures, and there is also a risk of damage to the inferior alveolar nerve.

Long Curved Jaw Angle Surgery

3. Long curved mandibular angle plastic surgery. This surgery uses an arc saw to make an arc-shaped osteotomy on the mandibular angle, increasing the distance between the cutting line and the mandibular alveolar nerve, which significantly improves the lateral view. The masseter muscle loses its attachment to the mandibular angle and slowly atrophies, and the problem of masseter muscle hypertrophy is also solved. In order to shape a beautiful curve of the jaw, it is sometimes necessary to remove some bone from the outer edge of the jaw, and it needs to be coordinated with the curve of the chin.

Advantages: One-time cutting, completed in one go, less damage, shorter time and faster recovery. Based on the aesthetics of the mandibular angle curvature, the distance between the cutting line and the mandibular alveolar nerve is increased, which has low risk and complies with the force principle of the mandibular angle. Special mandibular angle instrument to solve the problem of outer plate and inner plate. The curvature of the mandibular angle is aesthetically pleasing and has a beautiful appearance. Little to no sanding is required after a cut.
