Mandibular fracture osteosynthesis: a comparison of three techniques

Area of Science:

• Oral and Maxillofacial Surgery
• Trauma Surgery
• Biomaterials in Medicine

Background:

• Mandibular fractures are common injuries requiring surgical intervention.
• Internal fixation using miniplates is a standard treatment, but optimal placement techniques are debated.
• Champy's principles provide guidelines for miniplate placement to achieve stable fixation.

Purpose of the Study:

• To evaluate if adhering to Champy's principles in miniplate fixation for mandibular fractures minimizes patient morbidity.
• To compare outcomes between miniplate fixation (following and ignoring Champy's principles) and transosseous wire fixation.

Main Methods:

• Retrospective study of 205 patients with mandibular fractures treated between 1985 and 1990.
• Patients categorized into three groups: Champy's principles miniplate fixation (83), non-Champy miniplate fixation (40), and transosseous wire (TOW) fixation (82).
• Outcomes assessed via preoperative and postoperative variables, including complication rates and functional recovery.

Main Results:

• Preoperative variables were similar across all groups.
• Transosseous wire fixation group showed a statistically higher complication rate compared to miniplate groups.
• Miniplate fixation adhering to Champy's principles demonstrated reduced morbidity.

Conclusions:

• Adherence to Champy's principles in miniplate fixation for mandibular fractures is associated with lower morbidity.
• Miniplate fixation, particularly when following Champy's principles, is superior to transosseous wire fixation for managing mandibular fractures.
• Titanium miniplates are effective, especially when placed according to Champy's guidelines.
