This is a retrospective study on 452 patients with maxillofacial bone fracture. The patients were treated at the Dept. of Oral and Maxillofacial Surgery, WON KWANG UNIV. HOSPITAL from Aug. 1, 1984 to Sept. 30, 1988. The results were as follows. 1. The facial bone fractures occured most frequently in the twenties (35.3%)and male were predominant(75%) than female. 2. The most frequent etiologic factor was traffic accident. 3. The most common location of facial bone fracture was mandible(57%). Zygomatic bone & arch(39.9%) were most common on middle 1/3 of the face and symphysis(37.1%) were most common on the mandible. 4. The time from injury to treatment was variable from under the 1 week (65%) to over the 1 week(35%). In most case of the patients were treated beyond the 3 days(51.5%). 5. The relationship of intermaxillary fixation period and treatment method was an intimate relationship. The IMF period was reduced by the use of plate and screw osteosynthesis. 6. The weight loss was proportioned to intermaxillary fixation period.

As carotid-cavernous fistula is the major complication that can be occurred uncommonly after maxillofacial injuries, it is abnormal arteriovenous communication between cavernous sinus and internal carotid artery. Such an arteriovenous communication is most often the result of injuries, but need not be associated with bony fracture. It usually begins soon after an injury, but it may be delayed for as long as several months. It begins undramatically with eye pain, headache and slow protrusion of eye ball. A bruit may be heard above the eye with stethoscope. Close examination will reveal dilatation of superficial veins of the eyelid and forehead and periorbital edema. There will be complete or partial ophthalmoplesia of the affected eye. Compression of the common carotid artery on the ipsilateral side will reduce or obliterate the bruit. The lesion in the cavernous sinus is them demonstrable by angiography.

With the increase of population, dramatic urbanization, traffic, leisure and sports, the number of maxillofacial injury has increased markedly. Subsequently the number of motor vehicle accident, sports accident and industrial accident were increased and the number of oral and maxillofacial trauma patients were also markedly increased. A clinical study on 177 patients with facial bone fracture who visited Kangnam General Hospital during 4 years(1992-1995) was done by analysing sex, cause, fracture site, treatment method, complication and involvement of other body part. The results obtained were as follows : 1. The occurrence was more frequent in male than in female with the ratio of 4.2 : 1 and most frequently in twenties. 2. Violence was the most common cause of facial bone fracture. 3. Mandible was the most frequently occurred site and there were more cases of simple fracture(81.9%) than cases of compound fracture. 4. Simple fracture was most frequently occurred(44.0%). 5. In mandible fracture, simple fracture was 86.1%, fracture site was average 1.5 sites, most frequently in symphysis. 6. As treatment methods, open reduction(78.5%) was used more frequently than closed reduction(21.5%). 7. Post-operative complication occurred in 29.4% of the cases. 8. Other injuries that were related to maxillofacial fracture occurred in 28.2%.

A patient, who underwent partial masseter muscle resection and mandibular angle reduction at a plastic surgery clinic, visited this hospital with major complaints of trismus and dysesthesia. A secondary angle formation due to a wrong surgical method was observed via clinical and radiological examinations, and the patient complained of trismus due to the postoperative scars and muscular atrophy caused by the masseter muscle resection. The need for a masseter muscle resection in square jaw patients must be approached with caution. In addition, surgical techniques must be carefully selected in order to prevent complications, and obtain effective and satisfactory surgery results.

The indication for submandibular intubation is the requirement for intraoperative maxillomandibular fixation (MMF) in the presence of injuries that preclude nasotracheal intubation. Thus, We reported 2 cased of endotracheal intubations via submandibular approach that is applicable in patients with skull base fractures for a reliable general anesthesia. Endotracheal intubation via submandibular approach was applied during general anesthetic procedures for open reduction in three patients with Le Fort II, III or nasoorbitoethmoid (NOE) fractures. No complications due to submandibular intubation, such as infection, postoperative scarring, nerve injury, hematoma, bleeding, or orocutaneous fistula, were observed following submandibular intubation. Endotracheal intubation via submandibular approach is effective in patients with skull base fractures. In our method, the tube connector is removed in orotracheal intubation in order to avoiding the tube removal or displacement. The advantages of this method are very simple, safe, and to provide the good operation field.

Gunshot injuries can range from the most minor to the life-threatening. Multidisciplinary care is required for successful management of patients, In the acute phase, care may involve emergency surgeons, anaesthesists, neurosurgeons, ophthalmic surgeons, vascular surgeons, ENT specialist in addition to the oral and maxillofacial surgeons. Afterwards, definitive treatment of facial gunshot injuries depends ultimately on the abilities and skills of the oral and maxillofacial surgeons, and their appreciation of such injuries. The timing and sequence of the surgical procedures used for reconstruction and rehabilitation of maxillofacial gunshot injuries are crucial to a successful outcome and aesthetic result. If incorrect, they may lead indefinitely to infection, graft rejection, wound dehiscence with consequent multiple revisional operations and complication which will prolong hospital stay and increase treatment costs and morbidity on those patients. We present a gunshot case of a 46-year-old man who tried to commit sucide, and have avulsive and penerating wounds on the face and the neck. We removed the scattered bullets and fragments successfully and the wounds were closed primarily.

This is a retrospective study on maxillofacial fractures. This study was based on a series of 442 patients with maxillofacial fractures treated at Dept, of oral and Maxillofacial Surgery, College of Dentistry, Chon Buk National University from Jan, 1984 to Sep. 1988. The results obtained were as follows: 1. The ratio of Male/Female was 4.8 : 1, and 3rd decade (43.9%) was the highest age group in incidence. 2. Monthly incidence was the highest in Oct,(10.6%). 3. The most frequent maxillofacial fracture site was mandible (70.0%), and zygoma & zygomatic arch (13.6%), maxilla(11.7%) and nasal bone (4.7%) were next in order of frequency. 4. Traffic accidents (47.5%), fight(24.8%) were the most common causes of maxillofacial fractures. 5. The most frequent chief complaint was painful swelling(40.7%). 6. In mandibular fractures, the most frequent fracture site was symphyseal area(28.9%) and simple fracture was the most frequent in type of fracture (71.2%). 7. In maxillary fractures, fracture with other facial bones (64.5%) was more frequent than fracture of maxilla only. The most common type of fracture was unilateral fractures(37.1%). 8. In fracture of zygoma complex, zygoma fracture was the most frequent fracture type(40.3%), zygoma and zygomatic arch fx, (30.6%), zygomatic arch fx, (29.1%) were next in order 9. Open reduction was major method of treatment in maxillofacial fractures : Mandible (77.5%), Maxilla (61.3%), Zygoma complex(43.1%). 10. Maxillofacial fractures were most frequently combined with head injury(39.3%), and lower extremities(17.0%), upper extremities(13.6%) were next in order.

Objectives: Despite treatment, the pre-traumatic facial appearance of patients with maxillofacial fractures might not be able to be restored, and this difference can affect the person's quality of life (QoL). This study was designed to evaluate changes in QoL of people with maxillofacial fractures. Materials and Methods: The study population was comprised of participants with maxillofacial fracture and age- and sex-matched healthy controls without history of such fracture. QoL was measured using the World Health Organization Quality of Life BREF (WHOQOL-BREF) questionnaire, which was administered to the patients before treatment (Time 1), at 6 weeks post-treatment (Time 2), and at 12 weeks postoperatively (Time 3). The values were compared with those of healthy controls. The QoL was compared between closed reduction group and open reduction and internal fixation group. Results: The QoL scores of people with maxillofacial fracture before treatment were significantly lower (P=0.001) than those of healthy controls in all domains of the WHOQOL-BREF. The QoL scores in the psychological and social domains of patients with maxillofacial fracture at Time 3 were still lower than those of healthy controls (P=0.001). Conclusion: The QoL of patients with maxillofacial fracture was significantly reduced before treatment in all domains and remained reduced in both psychological and social domains weeks after treatment. Therefore, clinicians must be aware of and manage the residual psychosocial issues that can accompany the post-treatment period of maxillofacial injury.

It is a generally known fact that the patient can experience mouth opening limitation, mandibular deviation and malocclusion as a result of injury of tissues around the articular disc and complications even after successful open reduction surgery for fractured mandibular condyle. We have experienced a rare case of reconstruction using metallic condylar prostheses for a patient with complications resulted by unsuccessful management of fractured mandibular condyle. The case strongly suggested to us that careful selection of treatment methods should be taken for patient with fractured mandibular condyle. Accordingly, we are presenting a case in conjunction with reviews of fractured mandibular condyle.

Orbital injuries are common with facial trauma. Direct injuries to the globe are not rare but it can result in complications such as chemosis, subconjunctival hemorrhage and hyphema. Periorbital trauma or injuries to the extraocular muscles and blow-out fracture may result in lid edema, ecchymosis & ptosis and diplopia or limitation of ocular motion respectively. Indirect injuries to the optic nerve come up without any injuries but its complication is irreversible and severe such as loss of vision. The aim of this study is to review the literature on blindness or ptosis following facial trauma and present the cases of blindness after facial trauma and ptosis after mandibular fracture without specific clinical findings.
