RESUMEN
With hightened interest in bone contouring surgeries, newer and lesser invasive treatment modalities for bone augmentation surgeries are being introduced. Bone augmentation effects with long lasting injectable tissue fillers were studied. Between June, 2006 and November, 2008, 33 cases of small chin patients underwent chin augmentation via Royamid(R) and Radiesse(R) injections, 9 and 24 cases respectively. No complications were observed through the follow up period. Twenty six patients showed satisfaction with aesthetic results at 6 months follow up. In 7 cases, temporary swelling and erythema were observed. The augmentation effect lasted more than 6 momths in both Royamid(R) hard and Radiesse(R) groups. In 7 cases of Royamid(R) hard group, the aesthetic effects lasted more than one year. Long lasting tissue filler seems to be a good alternative treatment modality for bone augmentation surgery if approached with strict protocol indications and careful patient selection.
