Evaluation of neurosensory disturbance after using separators vs using chisels in bilateral sagittal split osteotomy
Keywords:
bilateral sagittal split osteotomy, neurosensory dysfunction, chisels and separatorAbstract
Aim: To evaluate neurosensory disturbance after using separators Vs chisels in bilateral sagittal split osteotomy. Methods: A total of (18 patients) 36 sides indicated for BSSO randomly assigned to 2 equal parallel groups; 9 patients (18 sides) treated using chisels (control group) and 9 patients (18 sides) were treated by separators (intervention group). The neurosensory disturbance was assessed for each side. Result: After one year follow up in separator group showed neurosensory dysfunction by 11.1% while chisel group showed 44.4%. Conclusion: The use of separators (splitting forceps and elevators) led to a low percentage of persistent post-operative neurosensory dysfunction.
