Management of Mandibular Symphysis and Para Symphysis Fractures Using a Single Mini Plate With Erich Arch Bar: Our Experience

摘要

Study was undertaken to study the use of single mini plate with Erich arch bar instead of two mini plates in fractures of the symphysis and Para-symphysis regions of mandible. To evaluate prospectively the clinical outcome, bony union, occlusal relationship, and complications associated with Single mini plate with Erich arch bar fixation of the symphysis and Para-symphysis fractures. A prospective study was conducted on patients with maxillofacial injuries reporting to the department of oral & maxillofacial surgery, IGGDC, Jammu, from January 2013 to February 2014. A total of 100 patients indicated for open reduction and semi-rigid fixation of isolated non-comminuted symphysis and para symphysis fractures were included in the study. Intraoral, open reduction & semi rigid fixation of non-comminuted symphysis and para-symphyseal fractures was performed using a single 2mm, 6-hole mini plate & 2 X 8mm mono cortical screws and Erich arch bars under general & local anesthesia. Patients with occlusal discrepancies were kept on 2 weeks of inter maxillary fixation by using elastics.The most common cause of the symphysis and para- symphyseal fractures was road traffic accidents followed by interpersonal rivalry, fall, sports injury, animal hit. Majority of the patients were between 20 - 45 years of age. Males sustained more injuries than females. All patients achieved bony union and there was no case of non-union, plate exposure or tooth injury. However malocclusion in 3% and wound infection (4%) were noted. For non-comminuted symphysis and para-symphysis mandible fractures, the application of single mini plate with mono cortical screws along with arch bars offers good surgical outcomes in most patients with minimal complications.
