Microplate Fixation without Maxillomandibular Fixation in Double Mandibular Fractures

Area of Science:

• Oral and Maxillofacial Surgery
• Trauma Surgery
• Orthognathic Surgery

Background:

• Maxillomandibular fixation (MMF) is the standard treatment for double mandibular fractures.
• Advancements in fixation techniques may enable treatment without MMF.
• Investigating alternatives to MMF for mandibular fracture repair is crucial.

Purpose of the Study:

• To evaluate the efficacy of anatomical reduction and microplate fixation without MMF for double mandibular fractures.
• To determine if this technique provides secure immobilization and correct occlusion.
• To compare outcomes with traditional MMF methods.

Main Methods:

• Thirty-four patients with double mandibular fractures underwent open reduction and internal fixation without MMF.
• Microplates with or without wire were used for bony fixation at two or three points.
• Interdental wiring was used for 6 weeks to enhance stability; immediate mouth opening was permitted.

Main Results:

• No major complications such as infection, plate exposure, non-union, or significant malocclusion were observed.
• Five patients experienced minor complications, with one reporting mild, persistent malocclusion.
• The technique demonstrated good stability and excellent adaptation, leading to successful fracture healing.

Conclusions:

• Anatomical reduction and microplate fixation without MMF is a viable treatment for double mandibular fractures.
• This approach simplifies the surgical procedure and improves patient comfort.
• The technique reduces complications and achieves secure immobilization with correct occlusion.
