Transoral approach alone in single miniplate osteosynthesis of angle fracture - our experience

Background and Objectives The ideal line of osteosynthesis in mandibular angle fractures indicates that a plate might be placed either along or just below the external oblique ridge. Some authors believe that using one miniplate at this line at the mandibular angle region provides sufficient strength to stabilize the fracture but others imply a second plate is required. Such controversies exist in the use of maxillomandibular fixation (MMF). The intention of the present study was to compare efficiency and complications of using one miniplate with and without MMF in mandibular angle fractures. Methods and Materials Forty patients with facial trauma with mandibular angle fractures including displaced and unfavorable fractures were categorized into two groups of 20 persons. In all patients, one miniplate was placed on the external oblique ridge. In the first group, patients had light maxillomandibular elastic bands just after surgery but no rigid MMF. In the second group, patients had rigid MMF for 2 weeks after surgery. Patients were followed to evaluate complications and treatment efficiency. Conclusions Our study showed that use of a single miniplate in the external oblique ridge is a functionally stable treatment for all types of angle fractures (including displaced and unfavorable fractures) except comminuted and long oblique fractures, which were not included in our study. Use of postoperative MMF did not improve the results.

Aim: This in-vitro experimental study compared the biomechanical behaviors of three single-miniplate osteosynthesis configurations used in the treatment of mandibular angle fractures. Methodology: Twenty-one synthetic polyurethane hemimandible replicas including the medullar and cortical portions were used in this study. The replicas were divided randomly into three groups (n = 5/group). Data from the three groups were compared using analysis of variance and the Tamhane T2 test. P values < 0.05 were considered to indicate significance. The replicas in all groups were fixed with 7-mm-long self-tapping screws and 2.0-mm four-hole miniplates in three different configurations external oblique, lateral angulus superior and lateral angulus inferior configuration. Results: The replicas were tested on a servohydraulic apparatus, and the data were transmitted to a computer for analysis of peak displacement and peak force. Peak load and peak displacement did no differ significantly among the three groups.. Conclusion: This experimental study showed that the torsional forces resulting from the fixation of miniplates for the treatment of mandibular angle fracture did not differ among the three configurations tested.

Angle Fracture

Blunt trauma to the parotid resulting in the formation of a sialocele is rare, with only three cases identified in the literature. We present a unique case involving a 32-year-old man with blunt trauma resulting in a left mandibular angle fracture. The patient underwent open reduction and internal fixation of the left mandibular angle fracture via transoral approach. At follow-up, after resolution of the edema from the injury, a sialocele was noted in the region of the left anterior parotid gland. The patient was treated conservatively with antisialagogues, pressure dressings, and multiple percutaneous aspirations that ultimately resulted in resolution of the sialocele.

Single Miniplate

Introduction Mandibular angle fractures can be treated by various methods, but even the most popular methods may not be able to give satisfactory results, as the pterygomasseteric sling and masticatory forces can result in displaced angle fracture. These displaced fragments cannot be satisfactorily retained by single miniplate fixation. The aim of this study is to assess treatment of displaced angle fracture with 3-D miniplate fixation. This study can also be considered as a therapeutic study with level V evidence. Materials and Methods This study was designed to assess the feasibility of 3-D matrix miniplate fixation in displaced angle fractures. Eighteen patients with displaced angle fractures were included in this study. Matrix miniplate fixation was done transorally under general anesthesia. Results All these cases were treated successfully, and common complications like infection (5.5% of patients), wound dehiscence (11%), paresthesia (16.7%), and malocclusion (11%) were observed in our study. Conclusions Three-dimensional miniplate fixation in displaced angle fractures provides better stability and function.
