Chin augmentation with nasal osteocartilaginous graft.
The use of the nasal hump removed during rhinoplasty was described by Aufricht in 1934 and 1958. In the past 10 years, the author has been using a similar technique but with significant variations. Before beginning the rhinoplasty surgery, the author dissects, through a submental incision, a subperiosteal mental pocket. Then, the osteocartilaginous nasal hump is removed; once the mucoperiosteum/mucoperichondrium is meticulously dissected, the nasal hump is tailored to achieve a mental form and the removed alar cartilage, nasal spine, or septal cartilage is used to fill or supplement the concavities of the hump. This report includes a total of 36 cases, 10 of which were controlled after 3 to 8 years of implantation by tridimensional computed tomography, from which the author observed an osteointegration with the mandibular bone and no reabsorption of the grafts or alteration of the structure of this bone. The patients revealed a high degree of satisfaction, and during the clinical examination, the author could not observe or palpate any distortion of the shape or projection of the chin. None of the grafts needed review or removal. This simple, fast procedure is a very good alternative for patients with some form of microgenia or when patients and surgeons are not likely to use alloplastic implants.
