The Pyramid Chin Augmentation: A New Technique

Abstract

The surgical approach to chin for esthetical purpose can be isolated or in a combination with other treatments like maxillomandibular surgery. Both possibilities include sliding genioplasty or implants of autologous or alloplastic materials. In this article, the authors present their new technique, the Pyramid Chin Augmentation.In January 2020, a 40-year-old male patient came to authors' observation asking for a great augmentation in the sagittal dimension of the chin, a better pronunciation of mandibular angles and of his cheekbones. The surgical treatment consisted in three different procedures at the same time: a chin wing osteotomy, a Pyramid Chin Augmentation and zygomatic PEEK custom-made malar implants. The pyramid was created on the body of the chin wing with a cortical bone graft from the oblique line of the ascending ramus of the mandible. The harvested bone was cut into strips of rectangular shape gradually shorter to be superimposed on the wing forming a pyramid. A fixation with 2 screws was performed and then was necessary to smoothen the edges of the bone layers.The result immediately after the end of the surgery was in line with the set goals. The mandibular angles were more prominent, the chin was more sagittal pronounced, and there was no evidence of depression in the symphysial region.The Pyramid Chin Augmentation Technique can be a valid tool in chin augmentation surgery and can also represent an effective procedure in the finishing touch of other facial surgery techniques.
