Techniques for maxillomandibular fixation: old and new.

Abstract

Purpose of review: Maxillomandibular fixation (MMF) is essential for many surgeries on the bony middle and lower face. MMF techniques have multiplied in recent years, each with unique benefits and drawbacks. This review catalogs MMF trends and evidence for and against the most prevalent MMF methods.

Recent findings: Traditional Erich arch bars remain the most robust technique in establishing MMF, particularly for comminuted/complicated fractures. Drawbacks are increased operative time required, wire stick injuries, poor oral hygiene, and gingival trauma. Screw-based techniques save considerable time but cannot stabilize comminuted fractures as adequately and risk tooth root and nerve damage. Embrasure wires offer time and cost savings but are solely for intraoperative use and uncomplicated fractures. Similarly, dental occlusion ties provide the benefits of reduced time and wire sticks, with the added capability of postoperative use, but require adequate dentition and minimally displaced fractures. Recent studies show decreased use of wire-based techniques, with increased adoption of hybrid systems and dental occlusion ties.

Summary: MMF techniques each have unique advantages and weaknesses. Selection should depend on surgical goals, including the severity of fractures, the need to maintain occlusion postoperatively, application/removal time, safety, and patient comfort.
