Mandible Fractures — Biomechanics, Occlusion, and Fixation Strategy

This episode reviews the core principles of mandibular fractures, focusing on diagnosis, biomechanics, occlusion, and fixation strategy.Topics include the ring-bone “pretzel” principle, the Five Ps of initial management, malocclusion as the key diagnostic clue, floor-of-mouth ecchymosis, the tongue blade test, mental nerve injury, marginal mandibular nerve injury, and imaging with Panorex versus CT.Biomechanics are reviewed through tension and compression zones, Champy’s ideal line of osteosynthesis, favorable versus unfavorable fractures, and the difference between load-sharing miniplates and load-bearing reconstruction plates.Surgical strategies are discussed by fracture pattern, including angle fractures, symphysis and parasymphysis fractures, condylar fractures, pediatric fractures, atrophic mandible fractures, teeth in the fracture line, MMF, arch bars, MMF screws, ORIF, and management of complications such as infection, malocclusion, nonunion, and hardware failure.Part of Dr. Lara’s Plastic Surgery Compendium — a high-yield audio reference for plastic surgery trainees and surgeons.DisclaimerThis podcast is intended for educational purposes only and is designed for medical students, residents, fellows, and practicing healthcare professionals.
