Transoral 2.0-mm locking miniplate fixation of mandibular fractures plus 1 week of maxillomandibular fixation: a prospective study.
OBJECTIVE
In this study, a 2.0-mm locking miniplate (LMP)/screw system was assessed in the treatment of mandibular fractures with a 1-week period of maxillomandibular fixation (MMF).


METHODS
Fifty mandibular fractures in 34 patients with a mean of 6.97 days of MMF were included in the study. The 2.0-mm LMPs were adapted along Champy's line of ideal osteosynthesis and secured with four 8.0-mm locking monocortical screws. All patients were followed for a minimum of 6 weeks. The incidence of soft tissue infections, nonunion, malunion, malocclusion, osteomyelitis, nerve injury, and tooth damage was prospectively assessed.


RESULTS
Primary bone healing was achieved in 98% of cases. Three complications (6%) were observed. Two minor complications of intraoral wound dehiscence and malocclusion were noted. A fibrous nonunion requiring 3 additional weeks of MMF was noted. No evidence of malunion, osteomyelitis, plate fracture, iatrogenic nerve injuries, or dental injuries was noted.


CONCLUSIONS
A single 2.0-mm LMP placed along Champy's line of ideal osteosynthesis with four 8-mm monocortical locking screws plus 1 week of MMF fixation is a reliable and effective treatment modality for mandibular fractures.
