Abstract

Facial asymmetry due to improperly reduced Condylar fractures is one of the Postoperative complications. Accurate reduction and fixation of Condylar fractures with symmetrical postoperative gain of ramus height is mandatory. Purpose: To assess the efficacy of utilization of the proximal segment as a guidance for Open reduction and internal rigid fixation in low sub-condylar Fractures. Patients and methods: For ten patients with unilateral sub-condylar fractures with age ranged from 32-51 years, the proximal fractured segment fixated to the plate was used a guidance for its reduction to the ramal stump. A cone beam CT was ordered for all patients immediate postoperative and the ramus height was measured on the fractured side and compared to the normal contralateral side. The Postoperative restoration of occlusion was reported. Results: For all patients, the restored ramus height of the fixated side was less than that of the non-fractured side with significant difference (p value= 0.009) and the postoperative occlusion was restored. Conclusion: Proximal condylar segment could be used as a guidance for Open reduction and rigid internal fixation of low sub-condylar fractures with subsequent restoration of the height of the ramus as compared to that of non-fractured side.
