title: The use of calcium phosphate cement paste for the correction of the depressed nose deformity.
abstract: The authors report the use of calcium phosphate cement paste as a material for correction of depression after nasal bone fracture, and evaluate its usefulness. Biopex R (Mitsubishi Material Corporation, Tokyo, Japan) was used in this study as calcium phosphate cement (CPC), which was developed in Japan. CPC injection was used in six patients (four women and two men) with depressed nose deformity after nasal bone fracture. The patients' ages ranged from 29 to 67 years (mean, 49 years), and the follow-up period ranged from 12 to 27 months. The amount of injected cement varied from 0.5 to 2.5 mL, approximately. There was no postoperative infection or allergic reaction in any patient. Clinical and X-ray photography findings showed that a reduction in volume of the injected cement occurred gradually as long as 7 to 8 months after surgery. After that period, the volume was mostly maintained. It seemed that the degree of reduction was approximately 10% to 15% of the original volume. Satisfactory results were obtained in all cases. The authors conclude that the use of CPC is an option for the correction of depressed nose deformity and that its application must be determined in each case, considering its advantages and disadvantages.
