Chin surgery (mentoplasty) is a plastic surgery procedure that modifies the shape and size of the chin, restoring balance and harmony to the facial profile. The chin plays a fundamental role in the aesthetic perception of the face: a chin that is too small, too large, or asymmetric can alter facial proportions and affect self-esteem. This procedure, often performed in combination with rhinoplasty (profiloplasty), achieves a balanced and harmonious facial profile.
Chin surgery is recommended for those who present facial profile disharmony related to the shape or position of the chin: • Receding or retruded chin, which gives an undefined profile appearance • Overly prominent or protruding chin, which creates an imbalance with the rest of the face • Chin asymmetries that compromise facial symmetry • Disharmonious facial profile, often in combination with nasal defects • Desire to improve jawline definition
The procedure is not recommended in the following cases: • Unresolved dental problems, such as malocclusion or missing teeth, which can affect chin position and may require orthodontic treatment first • Severe Class II or III malocclusion, which requires orthognathic (maxillofacial) surgery for adequate correction of the facial skeleton • Incomplete skeletal growth, typically under 18 years of age • Active infections in the chin area or oral cavity
The procedure takes about 30-60 minutes and is generally performed on an outpatient or day surgery basis. Full recovery occurs within 5-7 days, during which mild swelling and a sensation of tightness in the chin area are normal. A compressive dressing is applied for the first few days. Return to daily activities is quick, while sports activities should be avoided for approximately 3-4 weeks.
Yes, chin surgery is generally performed under local anesthesia with sedation, ensuring maximum patient comfort during the procedure without the risks of general anesthesia. The incision is made inside the mouth, in the lower gingival sulcus, or under the chin in a barely visible area, depending on the chosen technique and the type of correction needed.
Results are visible from the moment the dressing is removed, but the final outcome is appreciated after 2-3 months, once the swelling has completely subsided and the tissues have settled into their final position. The chin shape continues to stabilize progressively, and the result is long-lasting over time.
It depends on the case and the desired outcome. To increase the projection of a receding chin, a solid silicone implant is typically used, available in different shapes and sizes to match the patient's anatomy. To reduce an overly prominent chin or correct significant asymmetries, an osteotomy is performed instead, which involves surgical reshaping of the mandibular bone. In selected cases, fat grafting (autologous fat injection) may be an alternative for small volume increases.
