2. Chin reduction without mandible angle reduction.
3. Chin reduction with T osteotomy technique or V. line surgery.

1. Chin reduction with Mandible angle reduction

          Chin reduction with mandible angle reduction is an aesthetic surgery to reduce the chin, jaw angle, and mandible. During a chin reduction surgery, the surgeon removes a part of the bone tissue that makes up the chin to enhance and balance the appearance of the lower jawline, chin and neck. There is a range of techniques for this.

1.1 Chin reduction by resecting the angle of the chin bone is applicable where a patient has a small chin but is concerned only with the corner of the chin bone. After the surgery the chin will appear curved as desired.

1.2 Chin reduction by resecting the bone from chin angle to the middle of the mandible. This is applicable where the patient has a square and broad chin. The chin reduction starts from the middle of a mandible to balance a new lower jawline. This procedure is the most commonly performed technique for chin reduction.

1.3 Chin reduction by resecting (cutting) and shortening the chin bone is used  where the patient has a long chin without too much projection. This procedure shaves the lower jaw bone to make it smaller, curved and balanced.

1.4 Chin reduction by resecting (cutting) some bone all the way from the jaw to the chin to reduce the size. This technique is used for those with a wide jaw and broad chin. It improves the lower part of the face by making it appear shorter with a smaller & lower jawline. This is sometimes known as a horse shoe reduction.

2. Chin reduction without Mandible angle reduction

          A chin reduction alone is an aesthetic procedure for a chin that is too short or too long while leaving the jaw and mandibular untouched. The surgeon uses a saw to cut a small vertical line for reference, then slides the bone forward or backward and attaches screws and plate to ensure it stays in place. After the chin is adjusted forwards or backwards bone shaving is then possible. 


2.1 Chin forward surgery

This procedure is a correction of a short chin by moving the chin bone forward to make the chin look more sharp and natural.
