COMPARISON OF SINGLE VERSUS TWO PLATE FIXATION OF MANDIBULAR SUBCONDYLAR FRACTURE

Abstract

Non compression monocortical miniplate fixation of the mandibular sub-condyle is an accepted and reliable method for providing rigid internal fixation. The objective of this study was to compare the outcome of Single versus two plate fixation of mandibular sub-condylar fractures in terms of mouth opening and mandibular deviation. One hundred and twenty patients (120) coming to Mayo hospital, Lahore were selected and placed in two groups; group A (one miniplate fixation) Group B (two mini plates fixation). Postoperative results of single and two plate fixations were recorded after 3 weeks, 2 months and 6 months. Mouth opening was measured from upper central incisal tip to lower central incisal tip by using the metallic ruler in millimeters. The mandibular deviation was measured clinically. There were 40 (66.7%) males and 20 (33.3%) females in group A while in group B, 43 (71.7%) males and 17 (28.3%) females in group B with mean ages were 26.63±6.94 years in group A and 27.78±7.82 years in group B. Friedman test was applied in group A and B shows that there is a significant difference of mandibular deviation at a different time with P<0.001 Two miniplate fixation system on mandibular sub condylar fracture gives good stability, better mouth opening and absence of mandibular deviation as compared to single miniplate fixation.
