Abstract
Introduction
For the past decades, there has been a significant increase in head-maxillo-facial traumas, and mandible fracture occupies the second most frequent incidence of facial bone fractures, with incidence of about 38%. They are mainly caused by Road traffic accidents (RTA).
Aim
To study the effect of repairing the parasymphseal mandibular fractures with rigid fixation alone versus usage of lingual splint with rigid Fixation as regard occurring of mandibular flaring.
Patients and methods
A prospective randomized clinical study carried out in Benha University Hospital, Included 30 patients who suffered from isolated parasymphseal mandibular fracture. Patients were allocated into two groups; A (15 Patients underwent rigid fixation of parasymphseal mandibular fracture) and group B (15 Patients underwent rigid fixation of parasymphseal mandibular fracture with usage of lingual splint).
Results
Our study showed that in group (B) the mean bigonial width and bicondylar breadth were lower than that in group (A), this differences were statistically significant at 3 months after operation but there were not significant between both groups in the pre- operative time and just after operation. As regard complications, there were no significant differences between two groups as regard intra and post-operative complications
Conclusion
Adding lingual splint as adjuvant to rigid fixation will offer more stability and accuracy for reduction and prevent occurring of lingual splay of fracture fragments and mandibular angle flaring with subsequent minimize effect on tempromandibular joint.
