Introduction: 
This and similar studies show that surgeons can not rely on the immediate effect of scoring on the cartilage at the operation period. A straight septum on the operating table may deviate toward the opposite side by passing time.
 
Materials and Methods: 
During a period of 5 years, 283 cases have undergone rhinoplasty and in 227 patients, septoplasty accompanied the operation. Patients were divided into two groups of 125 and 158 cases. In the first group, septal deviation was corrected mainly by cross hatching of the quadrilateral cartilage accompanied by other modalities. In latter group, who were operated on recently, different methods of rigid fixation of septum in addition to the previous classic manner were used.
 
Results:
The outcome was over correction of septum toward the opposite side in 18 cases of the first group. No more iatrogenic over correction of septum was diagnosed in the second group, (P<0.0001).
 
Conclusions:
We recommend rigid fixation for correction of septal deviation instead of simple cross notching
