Outcomes of extra oral versus intraoral approach for Mandibular angle fracture reduction
Objective: To compare the outcomes of intraoral versus extraoral approach in the treatment of mandibular angle fracture.
Method: The randomised controlled trail was conducted at the Department of Maxillofacial Surgery, Mayo Hospital, Lahore Pakistan, from September 2016 to March 2017, and comprised patients of mandibular angle fracture who were divided into two equal extraoral group A and intraoral group B. . Baseline and post-operative data on 1st and 7th days as well as 3 months following the surgery was collected. Data was analysed using SPSS 20.
Results: Of the 100 patients, there were 50(50%) in each of the two groups. Mean age of group A was 32.28±7.79 years compared to 33.72±8.13 years in group B. There were 39 (78%) males in group A and 36(72%) in group B. The mean pain score at baseline in the groups was not significantly different (p=0.795). On the 7th day and 3 months post-operation, mean pain score was significantly lower in group A (p=0.002). Nerve complication in group A was significantly high compared to group A (p=0.005).
Conclusion: Extra oral approach for the management of mandibular angle fracture is better with regards to pain while intra-oral approach is less associated with nerve complications.
