The chin may be surgically modified to increase or decrease its projection, depending on the aesthetic requirements of each face.
Therefore surgical intervention that aims to change the facial profile increasing the volume of the chin, achieves this by placing a prosthesis secured to the sub periosteal jawbone through an incision in the buccal mucosa, centered in the mid-line and parallel to the lower dental arch, which is sutured with absorbable thread. Therefore it should not be removed.
This procedure is performed under local anesthesia with or without associated sedation and generally does not require hospitalization. The operating time is of approximately 20 minutes.
The side effects are similar to the implant of a malar prosthesis, but in this case it will be necessary to carry a chin cup during two weeks to control inflammation.
Another possibility to improve the chin is by performing a liposuction underneath the chin in order to remove excess fat.
The results are a neck with a defined profile. When there are problems of dental malocclusion, or there are defects in the structure of the jaw, the maxillofacial surgery may improve function and improve the look of the face.
On the other hand, when it is required to reduce the projection of a bulky chin, a surgery is performed known as mentoplasty through mandibular setback osteotomy, which involves modifying the jaw bone to reduce its projection.
It requires general anesthesia and 24 hours of hospitalization. The operating time is around 90 minutes. The side effects are again similar to the implant of a malar prosthesis, but also in this case it is necessary to carry a chin cup during two weeks.
