Craniomaxillofacial trauma management has continued to improve and evolve as a result of advances in technology and scientific inquiry. Controversies exist where there is little evidence-based literature to guide treatment in frontal sinus management, rigid versus absorbable fixation, open versus closed treatment of mandibular condyle fractures, extraction of teeth in the line of fracture, optimal timing for repair of mandible fractures, antibiotic use for facial wounds and fractures, and reconstructive materials in orbital fracture reconstruction...

PURPOSE: Posttraumatic edema in facial bone fracture patients may interfere with the operation field and delay the schedule. Thus, swiftly reducing the edema alleviates patient discomfort and advances the operation date. Ice packing and compression bandages are often used for such a purpose, but such methods are often inconvenient for the face. In this study, we aim to analyze the effect of light-emitting diode (LED) (590/830 nm)-based low-level laser therapy (LLLT) in posttraumatic edema in facial bone fracture patients...

In this clinical report, we present the management of a brain abscess that was presumed to be caused by radiation osteomyelitis of the mandible. The patient underwent chemoradiotherapy for oropharyngeal carcinoma on the left side at the Department of Otolaryngology of our hospital in 2000. Local recurrence or metastasis did not occur post-treatment. In January 2009, the patient was diagnosed with radiation osteomyelitis of the mandible on the left side, complicated by a pathologic fracture. In July 2011, numbness occurred in the left upper extremity and the patient was transferred to the emergency center of our hospital...

The reconstruction of mandible is a challenge with regard to aesthetic and reconstructive demands. The etiology of mandibular fractures is variable, trauma, pathology, bone infections. There are many materials that provide an excellent form of rehabilitation for these defects, where the autogenous graft presents important characteristics that favor a greater success rate. Furthermore, the rapid prototyping method is quite interesting, because it brings a series of advantages to the surgeon, like reducing the operative time, among others...

REVIEW
Srinivasa R Chandra, Karen S Zemplenyi
Pediatric maxillofacial fractures are rare owing to anatomic differences between juvenile and adult skulls. Children's bone is less calcified, allowing for "greenstick fractures." The overall ratio of cranial to facial volume decreases with age. In children, tooth buds comprise the majority of mandibular volume. The most common pediatric craniomaxillofacial fractures for children ages 0 to 18 years old are mandible, nasal bone, and maxilla and zygoma. Growth potential must be considered when addressing pediatric trauma and often a less-is-more approach is best when considering open versus closed treatment...

REVIEW
Alexis M Strohl, Robert M Kellman
Treatment of subcondylar fractures has been the subject of debate for many years. Options for treatment include physical therapy, elastic maxillomandibular fixation, and open repair. Proper imaging and clinical evaluation are imperative when deciding on the best management option. In the past, most subcondylar fractures were treated with a closed approach. Recent data support open repair, when feasible. Studies show increased interincisal opening, lateral excursion, and protrusion with less mandibular shortening, jaw deviation, and pain...

A fracture of the mandible is a common trauma presentation amongst young males and represents one of the most frequently encountered fractured bones within the viscerocranium. Historically, assault was the dominant contributing factor but now due to the increased number of vehicles used per capita, motor vehicle accidents are the primary cause. Mandibular fractures can be classified anatomically, by dentition, by muscle group and by severity. The fracture may also be closed, open, comminuted, displaced or pathological...

A mandibular fracture alone rarely causes a life-threatening injury. The aim of this paper was to emphasise the importance of prompt identification of the radiological signs of a flail mandible in a patient with maxillofacial trauma who eventually needed definitive management of her airway.

REVIEW
Jung-Ho Lee
The management of mandibular angle fractures is often challenging and results in the highest complication rate among fractures of the mandible. In addition, the optimal treatment modality for angle fractures remains controversial. Traditional treatment protocols for angle fractures have involved rigid fixation with intraoperative maxillomandibular fixation (MMF) to ensure absolute stability. However, more recently, non-compression miniplates have gained in popularity and the use of absolute intraoperative MMF as an adjunct to internal fixation has become controversial...

OBJECTIVES: For decades, Erich arch bars have been a standard in establishing maxillo-mandibular fixation (MMF). While reliable, the approach risks sharps injury, consumes operating room time, and inflicts gingival trauma. Newer technologies including screw-based techniques and "hybrid" techniques have improved MMF by reducing sharps injuries and operating room time, but risk injury to tooth roots, nerves, and gingiva. This study aims to establish the application, strengths, and limitations of dental occlusion ties as a novel alternative in maxillo-mandibular fixation...

A 47-year-old woman was referred for surgical treatment of osteomyelitis of the mandible. She had already undergone three previous surgeries. Pre-anesthetic airway evaluation predicted a difficult airway, due to the thin, retro-positioned mandible, tongue, and atrophic changes in the lips and soft tissue. We inserted packing gauzes in the buccal mucosa for easier mask fitting and ventilation. During direct laryngoscopic intubation with a nasotracheal tube (NTT), fracture of a thin mandible can easily occur...

The mandibular fractures in pediatric patients are rare, and they can need a fast and safe treatment. We present a case of a pediatric patient with "Andy Gump" fracture, resulting in a retrognathic mandible, distress to breathe, and functional discomfort to the patient caused by a cycling accident. The treatment was successful with the fast release of airway path and use of titanium plates to fix the fracture.
