ABSTRACT

Objective: To compare the outcomes in terms of complications of rigid fixation (two miniplates Osteosynthesis) versus non-rigid fixation (maxillomandibular fixation alone) for treatment of displaced Mandibular Parasymphysis fracture.

Study Design: Randomized controlled trial

Place and Duration:Conducted at Bolan Medical College/ Civil Hospital Quetta for six months duration from July 2016 to December 2016.

Methodology: Total 116 patients of both genders were included in this study. Pre-operatively a written consent was taken from each patient by the primary investigator of this study. Patients were equally divided into two groups, 58 patients in each group. Group A treated with rigid fixation while group B treated with non-rigid fixation. Clinical examination, X-Ray Orthopentomogram of face were taken preoperatively. These measures were also be used to assess post-operative complications i.e. (surgical site infection, malocclusion, nerve damage, limited mouth opening)during follow-ups of the patient. Data was analyzed by SPSS 24.0.

Results: Mean ± SD of age in group A was 29.20±6.143 years and in group B were 29.10±5.280 years. In Gender distribution of group A 70.68% were male and 29.31% were female and in group B the distribution of male and female was 74.13% and 25.86% respectively. By comparing both groups, the non significant association were found between limited mouth opening, malocclusion, nerve damage and surgical site infection i.e. P (0.140, 0.406, 0.122 and 0.452) respectively.

Conclusion: It is to be concluded that rigid and non-rigid fixation provides optimal stability for healing and allow immediate function of stomatognathic system but high complications rate. Regarding postoperative infection, malocclusion, nerve damage, limited mouth opening, and statistically non-significant difference was found between the two treatment groups.
