ABSTRACT
Aim: To Evaluate the Retromandibular transparotid approach in open reduction and Internal Fixation (ORIF) for Subcondylar Fracture of Mandible.
Objectives: To report on - Maximum Mouth Opening (MMO), Occlusal derangement(OD), Deviation of mandible on mouth opening (DOM), scaring , salivary fistula, and facial nerve weakness (FNW) associated with Retromandibular transparotid Approach in open reduction and Internal Fixation (ORIF) for Subcondylar Fracture of Mandible.
Methodology: The prospective study with sample of 16 subjects fulfilling the stated inclusion and exclusion criteria were subjected to RMTP Approach in open reduction and ORIF for Subcondylar Fracture of Mandible based on Eckelt and Rasse Criteria. The stated objectives were evaluated by comparing maximum mouth opening and scar lengths before and after surgery follow up of 3 months. The other complications are presented in percentages with recovery time in months.
Results: RMTP approach was successfully employed in 16 cases. No post-operative incidence of salivary fistula, OD and DOM on mouth opening were noted. Facial nerve weakness was observed in 4 cases during immediate post-operative review. In all the cases the mouth opening significantly increased from 20.06± 4.33 mm to 39.88±4.13 mm postoperatively. Post-surgery scaring significantly reduced in 3 months follow-up review.
Statistical analysis: paired t tests.
Conclusion: The open reduction and internal fixation method of subcondylar fracture with the Retromandibular transparotid approach was found to be an effective and safe technique having a good access, esthetic and functional results with low morbidity.. Facial nerve weakness was found to be transient change which was lost in 3-4 months.
