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
Bioglasse 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 e 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. |
