Genioplasty is a surgical correction that usually involves the risk of bleeding. Controlled hypotensive anesthesia is usually used before osteotomy, so the anesthetist is also important.

Genioplasty includes a variety of surgeries to correct overdevelopment, underdevelopment of the jaw, chin deviation, and other three-dimensional abnormalities involving the front, back, up and down, and left and right of the chin. Genioplasty based on the mandibular muscle pedicle bone flap is currently the best surgery to correct various chin morphological abnormalities.

Because the chin varies greatly among individuals, even within the same type of deformity, there are obvious differences between patients. The best effect of genioplasty is to achieve coordination with all parts of the craniofacial area. Therefore, , the surgery should be designed based on individual facial shape.

Indications:

1. Shorten the anterior and posterior diameter of the chin and correct protruding chin.

2. Move the chin forward to increase its anteroposterior diameter and correct chin retrusion deformity.

3. Increase the height of the chin and correct the vertical deficiencies of the chin.

4. Reduce the height of the chin and correct the vertical length of the chin.

5. Increase the width of the chin and correct the insufficient left and right diameters of the chin.

6. Rotate the chin to correct asymmetrical deformities such as chin deviation.
