Immediate Post-Operative Complications in the Treatment of Mandibular Fractures at Angle Region by Rigid Fixation Using Mini Bone Plates With or Without Intermaxillary Fixation.
Ann Pak Inst Med Sci Jan ;10(1):27-32.

Objective: The purpose of this study was to determine the impact of intermaxillary fixation in immediate post operative inflammatory phase in treatment of mandibular fractures at angle region by rigid fixation using mini bone plates. Place and Duration: The study was conducted in the department of Oral and Maxillofacial Surgery, Pakistan Institute Medical Sciences, Islamabad, Pakistan from July 2005 to June 2009. Materials and Methods: This study comprised 60 patients within the age group of 12-60 years divided into two treatment groups. Group (A) was treated by titanium bone plating with IMF for 10 days and group (B) by bone plating without IMF. All the fracture was treated by Open Reduction and Internal Fixation (ORIF) via intra-oral approach. Results: Majority of the patients were males (93.3%) with a male to female ratio of ratio of 14:1. Mean age of the patients was 28.13 years (12-60 years). The commonest etiology was road traffic accidents. The immediate post operative complications in 6, 12 and 72 hours gave the impact of acute inflammatory phase. The results demonstrated significantly higher incidence of post operative pain in patients who underwent rigid fixation without IMF (p= 0.0043). However post operative transient airway obstruction was evaluated at a higher frequency in patients treated with IMF (p = 0.024). Conclusion: Titanium mini plates offer sufficient stabilization of mandibular angle fractures with a significant reduction in immediate post operative complications if IMF period is extended up to 10 days.
