Chin augmentation using surgical implants can alter the underlying structure of the face, providing better balance to the facial features. The specific medical terms mentoplasty and genioplasty are used to refer to the reduction and addition of material to a patient's chin. This can take the form of chin height reduction or chin rounding by osteotomy, or chin augmentation using implants. Improving the facial balance is commonly performed by enhancing the chin using an implant inserted through the mouth. The goal is to provide a suitable projection of the chin as well as the correct height of the chin which is in balance with the other facial features. This operation is often, but not always, performed at the time of rhinoplasty to help balance the facial proportions. Chin augmentation may be achieved by manipulation of the jaw bone (mandible) and augmentation utilizing this technique usually provides a more dramatic correction than with the use of prosthetic implants. Chin implants are used to build a better profile. . Chin implants help to improve the proportion of facial features. It is also an excellent technique in the cosmetic industry that can improve your jawline and neck and thereby giving you more confidence and self-esteem. Patients' own bone is donated from ribs and from part of the pelvis (the ilium). Use of donated bone implants in chin augmentation, even the patient’s own, appears to be associated with a higher rate of infection, even after the implant has been in place for decades. Chin augmentation is still popular because it is a relatively easy operation for the patient while producing noticeable changes in the silhouette of the face. This type of surgery is usually performed by an oral and maxillofacial surgeon, otolaryngologist, or plastic surgeon. T-osteotomy method T-osteotomy method (or mini V-line) is used to narrow and lengthen the chin using an osteotomy technique formulated by Korean surgeons. The surgery is performed under general anesthesia (orotracheal intubation) using an intraoral approach. Using a double-bladed reciprocating saw, a horizontal osteotomy is performed, leaving a small portion of bone in the middle. Then two vertical osteotomies are performed in an upside-down trapezoidal shape which is excised. The bones remaining from the horizontal osteotomy are then attached and adjusted to lengthen the chin, and advanced forward for an additional frontal chin projection if required. Pre-bent titanium plates and screws are used to fixate the bone to its
