Background: For proper recovery from craniofacial fracture, it is necessary to establish guidelines based on trends. This study aimed to analyze the patterns and causes of craniofacial fractures. Methods: This retrospective study analyzed patients who underwent surgery for craniofacial fractures between 2010 and 2017 at a single center. Several parameters, including time of injury, region and cause of fracture, alcohol intoxication, time from injury to surgery, hospitalization period, and postoperative complications, were evaluated. Results: This study analyzed 2708 fracture lesions of 2076 patients, among whom males aged 10 to 39 years were the most numerous. The number of patients was significantly higher in the middle of a month. The most common fractures were a nasal bone fracture. The most common causes of fracture were ground accidents and personal assault, which tended to frequently cause more nasal bone fracture than other fractures. Traffic accidents and high falls tended to cause zygomatic arch and maxillary wall fractures more frequently. Postoperative complications-observed in 126 patients-had a significant relationship with the end of a month, mandible or panfacial fracture, and traffic accidents. Conclusions: The present findings on long-term craniofacial fracture trends should be considered by clinicians dealing with fractures and could be useful for policy decisions.

CT/MRI images were frequently taken to evaluate the anatomic structure and disease status, and to plan the treatment modality for oral and maxillofacial surgery. However, surgeons have many difficulties in reading and understanding 2D images without long time experiences. This study presents the method of 3D reconstruction with fine CT slices and its clinical application. We applied this method a clinical patient with oral and maxillofacial trauma and produced 3D reconstructed model which shows the fracture line in panfacial area and bone defect.

The technique of submental intubation in patient with multiple facial fracture and skull base fracture was originally described by Altemir. Not only is intermaxillary fixation feasible when using this surgical technique but a good field of vision is acquirable, and postoperative complications due to tracheostomy can be prevented. After Altemir presented submental intubation, many modified techniques were reported, applicable not only to trauma patients but also to elective surgeries such as orthognathic surgery including Lefort II or III osteotomy. This technique is easy to use, rapid and free of complications compared to alternative intubation method especially tracheostomy for multiple facial trauma patients.

Submental or submandibular intubation has been reported to cause fewer complications than tracheostomy. However, the risk of infection is always inherent because oral wounds are exposed to microbial flora and bacteria in the oral cavity. A novel technique of submandibular intubation was devised to reduce infection and injury to the soft tissues. We would like to report a novel safe technique that can be performed in patients requiring submental or submandibular intubation. This is the first report of submandibular intubation using a sterile disposable camera cable drape. This novel technique of submandibular intubation is safer, more sterile, easier, and less invasive than conventional submandibular intubation.

Fracture of frontal bone is infrequent, but may have serious complications because of their proximity to the brain, eyes and noses. Fractures of the frontal area range from 5% to 15% of all facial bone fracture and include supraorbital rim and frontal sinus. As frontal bone fractures most frequently occur in the multiply injured patient, a thorough clinical and radiological examination of the patient is required before diagnosis and treatment plans are established. Sometimes coorperative treatment with other department is required. It is specially considered that incision for access to frontal region and surgical methods for open reduction, cranialization, cannulization, sinus obliteration. After surgical or conservative treatment, it may have complication. Complication of frontal bone injury vary in severity and may occur at several years after the incidents. The major types of complications are those that occur directly at the time of injury, infection and chronic problems. This is clinical study on 31 patients with frontal bone fracture, at department of oral and maxillofacial surgery in dental hospital of Wonkwang university during past ten years. The results were as follows; 1. The sex ratio of all patients is 29 (94%) male to 2 (6%) female, the average age is 33 and the prominent groups are 2nd, 3rd decade age. 2. The causative factors are mostly traffic accident 22 cases (70%) and fall dawn, industrial accidents, so on. 3. The 17 cases has shown alert mental status, but neurologic problems is in 14 (45%) cases in initial accessment. 4. Associated facial bone fractures are prominent in the maxilla (42%) and panfacial fracture (39%). 5. Involved general problems are in department of neurologic surgery problems (65%), orthopaedic problems (23%) and ophthalmologic problems (19%) in order. 6. Open reduction has done in 15 cases and 16 cases with conservative management. 7. Postoperative complications are chronic headache (42%), esthetic problems (39%) and ophthalmologic problems (35%)in order.

Invasive or non-invasive reduction of fractures could be conducted as treatments of traumatic maxillofacial bone fractures. But when suboptimal reduction or malunion of maxillofacial bone fracture occurs, malocclusion could occur as a result of the lost relationship of the mandible and midface. This malocclusion is called post-traumatic malocclusion and orthognathic surgery, orthodontic treatment, selective grinding and prosthetic reconstruction are suggested as treatments for post-traumatic malocclusion after securement of stable TMJ. Stable TMJ is essential for occlusal rehabilitation to prevent occlusal change and relapse of malocclusion. Centric relation and adapted centric posture are suggested as start points of occlusal rehabilitation because they are most stable TMJ position. This case report presents a case in which post-traumatic malocclusion occurred after reduction of panfacial fracture. To rehabilitate full mouth occlusion, selective grinding and prosthetic reconstruction of implant supported fixed prostheses were conducted in centric relation and showed satisfying results in functional and occlusal aspects.
