Application of Heterogenous decalcified bone in the repair of nasal and aural deformities

Objective To summarize the experience of application of heterogenous decalcified bone (HDB) in the repair of nasal and aural deformities in order to find an ideal filling material. Methods HDB as filling material were used in plastic surgery on 21 cases. There were 10 cases of saddle noses and irregular nasal deformities, 6 cases of traumatic defect of auricles and 5 cases of total nasal reconstruction with nasal tips and short columellae filling.Results There is only one case with the necrosis of tips of flap healed after the removal of HDB. All the tocalother cases showed satisfactory result.Conclusion The resource of HDB is abundant. As a desired filling material, HDB is also easy sculptuse, nonrejection and harmless and nontoxic to human body.
