Diagnosis

Diagnostic evaluation consists of a facial analysis as well as a complete dental and medical history. The chin is one of the three most significant parts of the face from an aesthetic standpoint, the others being the forehead...

and the nose. Many patients who are concerned about the size of their nose, for example, can be helped by having a too-small chin augmented as well as having the nose reshaped. In the facial analysis, the face is divided into thirds, with the mouth and chin in the lowest third. The surgeon compares the proportions of the features in each third in order to determine the most suitable procedure for restoring balance. The patient will be photographed from several angles to document the condition of the chin before surgery.

The dental history and x ray studies of the head and jaw are necessary in order to determine whether the facial disproportion can be corrected by an implant or simple reduction, or whether orthognathic surgery is required. Patients who have severe malocclusion (irregular contact between the teeth in the upper and lower jaws) or deformities of the facial bones are usually referred to a maxillofacial specialist for reconstructive surgery.

Lastly, the surgeon will evaluate the patient for any signs of psychological instability, including unrealistic expectations of the results of surgery.

Preparation

Patients should stop smoking and discontinue all medications containing aspirin or NSAIDs for two weeks prior to mentoplasty. If the surgeon is planning to make a submental incision, the patient should use an antibacterial facial cleanser for two days before surgery. Patients scheduled for an intraoral approach should rinse the mouth with mouthwash three times a day for two days before surgery. They should not eat or drink anything for eight hours prior to the procedure.
