Comparing the Post-operative Complications of Mandible Angle Fractures Treated by Extra Oral versus Intra Oral Reduction Approach

Abstract

Objective: To compare post-operative complications of mandible angle fractures treated by extra oral versus intra oral reduction approach.

Study Design: Randomized controlled trial study.

Place and Duration of Study: This study was conducted at the Oral and Maxillofacial Surgery, Jinnah Postgraduate Medical Center, Karachi and research was started from 25^th June 2021 to 24^th December 2021.

Materials and Methods: A total of 202 patients of angle fracture of mandible were enrolled and divided in equal two groups A & B, each group having 101 patients. In group A extra oral reduction approach and in group B intra oral reduction approach will be used for angle fracture of mandible.

Results: Pain was present in all our study cases on 1^st to 2^nd visits in both A and B groups with mean pain score 6.03 ± 0.44, 4.94 ± 0.42 and 5.98 ± 0.48, 3.96 ± 0.52 respectively while on 3^rd visit less pain was observed in group B 57.4% with mean pain score 1.93 ± 0.91 and 70.3% with mean pain score 2.51 ± 1.33 which is more in group A cases. (p=0.000). In group A, 22.8% patients had infection and no any case was observed in group B caseson first visit. Also in group A, majority of cases showed infection on 1^st and 2^ndfollow up visits 25.7% and 16 (15.8%) respectively.

Conclusion: We observed more post-operative complications of mandible angle fractures treated by extra oral as compared to intra oral reduction approach
