ABSTRACT
This study was designed to evaluate the biocompatibility and performance of Bioglass® in reconstruction of saddle nose deformity and to compare the results of 2 different surgical approaches. Twenty patients with traumatic saddle nose deformity were included in this study. They were classified into 2 groups according to surgical approach: Group (A) 10 patients with saddle nose deformity were reconstructed using Bioglass® through internal nasal approach and Group (B) 10 patients with saddle nose deformity were reconstructed using Bioglass® through external nasal approach. A pre-operative photo to nose deformity and another photo 6 months post-operatively were taken for every patient in this study. Also CT scan one week and 6 months post-operatively was done for every case to compare the density of Bioglass ® and adjacent bone measured by hounse field unit ( H. F. U) to confirm bone formation. In Group (A) there were 6 cases with incomplete reconstruction and 4 cases with irregularity, while all cases in Group (B) were showed complete regular reconstruction. Bone formation was occurred in all cases as the density of Bioglass® became near to that of bone density.
Bioglass® is a highly suitable synthetic material for correction of saddle nose deformity. We recommended the use of this material through an external nasal approach. By this approach we can estimate the actual amount needed for correction and equal desperation of the particles will be achieved. However, there is minimal scar which less ugly than Saddle nose deformity.
