Genioplasty includes a variety of surgeries to correct overdevelopment of the jaw, dysplasia, and jaw deviation, which involve the anterior and posterior, upper and lower, and left and right three-dimensional direction abnormalities of the chin.The mentoplasty based on the muscle pedicle bone flap of mandibular chin is also the best surgery for correcting various abnormality of chin.Due to the great individual differences in the chin, even in the same deformity, there are obvious differences among patients. The best effect of chin plasty is to achieve the coordination with all parts of the craniofacial. Therefore, the operation should be designed according to the individual face type.

Indications

1. Shorten the front and back diameter of the chin and correct the front protrudence of the chin.

2. Increase the front and back diameter of the chin and correct the chin retraction deformity.

3. Increase the height of the chin and correct the deficiency in the vertical direction of the chin.

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

5. Increase the width of the chin and correct the deficiency of the left and right diameter of the chin.

6. Rotate the chin to correct the chin deviation and other asymmetrical deformity.

7. the above several conditions can exist in the same patient, design time.Simultaneous abnormal factors should be considered.This operation is often combined with other orthognathic surgery to correct complex dental and maxillofacial deformities.

Surgical operation steps

Anteroposterior mental underdevelopment is the most common and earliest mental deformity that people pay attention to.Severe chin retraction cases, its lateral appearance is “beak” shape, seriously affect the appearance of beauty.Advancement genioplasty is the most commonly used procedure for correcting posterior chin deformity.The principle of the intraoral approach is to cut the joint bone in the middle of the mandible at the level of the root tip of the lower anterior teeth and the lateral submental foramina, maintain the integrity of the blood supply pedicle of the lingual soft tissue and muscle after the incision, move the bone forward to a new position and re-fix it with the mandible.Because the soft tissue attached to the labial and buccal sides of the chin bone block also moved forward, the chin retraction deformity was corrected.

osteotomy line is usually located 0.5 cm below the root tip to prevent the tooth tip from being damaged and to ensure the nerve and blood supply to the tooth.When the lingual bone plate is cut off, the operation should be gentle and accurate to avoid damage to the soft tissues such as the lingual muscle pedicle, resulting in hematoma and swelling of the oral floor after operation, and pushing the tongue back and affecting breathing.The soft tissue pedicle of the muscles below the osteotomy line should be protected, especially in the mid-mental region, including the anterior belly of the digastric muscle and the attachment point of the geniohyoid muscle at the posterior margin of the submental bone, to ensure the blood supply to the osteotomy. Internal fixation is performed with a titanium plate or screw. Avoid damage to the tip of the tooth.Layered suture.The mentoplasty is flexible and can be performed in a number of ways: horizontal osteotomy and forward displacement; Horizontal osteotomy and anterior lengthening; Double step horizontal osteotomy and anterior osteotomy; Horizontal osteotomy, shortening and retrograde; Horizontal osteotomy and anterior shortening;Horizontal transposition; Triangular segment amputation; Horizontal rotary transposition; Widening of the chin segment; Chin constriction.
