Abstract:
Objective:To assess the possibility of allogenic decalcified bone matrix used as material to rebuild the midline structure in rhinoplasty.Methods:From January 2018 to June 2018, allogenic decalcified bone matrix was used as material to rebuild the midline structure in rhinoplasty in six carefully selected patients, who did not have enough septum and conchal cartilage to be harvested and refused to have costal cartilage harvested. Nasal length and tip projection were measured preoperatively, 2 weeks and 18 months postoperatively.Results:All patients were satisfied with the appearance of the nose two weeks after operation. However, four patients experienced the reduction of tip projection in 18 months postoperatively and needed revised rhinoplasty. In the revised operation, the implanted allogenic decalcified bone matrix could not be removed integrally. Matrix residues were harvested and observed under the microscope, which showed fragment of the matrix and fibers surrounded by inflammatory cells and foreign-body giant cells. No osteocyte was found in the ground substances of bone.Conclusion:The commercial allogenic decalcified bone matrix applied in this study is not recommended to use as the material for rebuilding the midline structure in rhinoplasty.
