title: Nasal augmentation using calcium phosphate cement.
abstract: This report describes a simple technique for augmentation rhinoplasty using calcium phosphate cement paste for postoperative and posttraumatic nasal deformities. This biomaterial was used to correct traumatic nasal bone deformity in one patient and for augmentation rhinoplasty after removal of the nasal implant in two patients. These patients were followed for a minimum 6 months and a maximum of 26 months. The esthetic results were satisfactory with no complication. Calcium phosphate cement consisting of alpha-tricalcium phosphate, dicalcium phosphate dibasic, and tetracalcium phosphate monoxide has been used for bone replacement and augmentation because of its good biocompatibility and osteoconductivity. This technique is easy and safe. It seems to be a suitable material for augmentation rhinoplasty in the Orient. Its long-term safety and reliability require proof with longer follow-up periods, however.
