CHIN AUGMENTATION USING DICED CARTILAGE

Eight patients with microgenia have undergone augmentation with diced nasal cartilage. Cartilage grafts were harvested from the nose during rhinoplasty. These grafts were cut into 0.5 to 1.0 mm pieces using a # 11 blade and were wrapped in one layer of Surgicel (oxidized regenerat ed cellulose). This cartilage mass was inserted into the chin pocket. All patients underwent clinical evaluation, magnetic resonance imaging (MRI), and photography. These investigations showed that diced cartil age grafts maintained 75% of their dimensions at six months after impl antation. The follow-up period was 12 months, and the aesthetic result s were satisfactory.
