Purpose: This study was performed to investigate the incidence, types of fracture, treatment, associated fracture and complications in patients with nasal bone fracture. Materials and methods: Clinical examination, patient's records and radiographic images were evaluated in 230 cases of nasal bone fractures who were treated at the Department of Oral and Maxillofacial Surgery, Chonnam National University Hospital for recent 5 years; from January 2002 to December 2006. Results: 1. The age of patient was ranged from 4 to 77 years (mean age=36.6 years); Males was 75.7% (n=174), and females 24.3% (n=56). 2. The cause of the nasal bone fracture in this study was a fall or slip down (28.8%, n=66), sports accident (26.0%, n=60), fighting (21.3%, n=49), traffic accident (9.6%, n=22), industrial trauma (7.8%, n=18), and the others (6.6%, n=15). 3. For the patterns of fracture, simple fracture without displacement occured in 10.4% (n=24). Simple fracture with displacement without septal bone fracture was found in 49.5% (n=114). Simple fracture with displacement in company with septal bone fracture showed in 32.6% (n=75). Commiuted fracture with severe depression was presented in 7.4% (n=17). 4. The reduction the displaced nasal bone was carried out in 2 to 10 days (mean 6.8 days) after the injury. 5. Nasal bone fracture associated with Le Fort I fracture (6.5%, n=6.5), Le Fort II fracture (7.4%, n=17), Le Fort III fracture (1.3%, n=3), NOE fracture (13.9%, n=32), ZMC fracture (17.4%, 40), maxillary bone fracture (8.3%, n=19), orbital blow-out fracture (15.7%, n=36), frontal bone fracture (1.3%, n=3) and alveolar bone fracture (10.9%, n=25). 6. The major type of treatment method was closed reduction in 90% (n=207), open reduction in 3% (n=7), and observation in 7% (n=16). 7. There were some complications such as ecchymosis, hyposmia, hypo esthesia and residual nasal deformity which are compatible. Open rhino-plasty was conducted for 3 patients who had residual nasal deformity. Conclusions: These results suggest that most of nasal bone fractures are occurred physically active aged groups(age 10-49 years) and could be treated successfully with closed reduction at 7 days after the injury.

Background: This study aimed to evaluate the structural changes of temporomandibular joint immediately after condylar fractures with magnetic resonance imaging (MRI). Method: We evaluated 34 subjects of condylar fractures with MRI. The position, shape, and signal intensity of the condyle, disc, and retrodiscal tissue were analyzed with MR images. Results: Immediately after trauma, the disc was displaced with the fractured segment in almost all cases. And, the changes of signal intensity at the retrodiscal tissue were found but less related to the degree of fracture displacement. And, the high signals were observed almost at all fractured joint spaces and even at some contralateral joints. Conclusions: The displaced disc as well as the increased signal intensity of the joint space, condylar head, and retrodiscal tissue demands more attention to prevent the possible sequela of joint.

Purpose: Globe displacement due to a blowout fracture is a rare clinical phenomenon. The authors present reduction of a globe displacement to the maxillary sinus due to trauma suffered in a fall and the reconstruction of a large defect left in the medial and inferior orbit. Methods: A 39-year-old male patient was unable to open his left eye after being struck on the periorbital area by a metal edge. Laceration was not noted in that area but we were unable to observe the intraorbital globe. A facial computed tomography (CT) scan showed that the globe was displaced through the maxillary sinus. A transconjunctival approach was used to access the infraorbital margin and the globe entrapped in the inferior margin of the orbit was successfully reduced. A large defect in the medial and inferior orbit was reconstructed using a graft from the iliac bone. Results: In 5 months after the operation, no atrophy of the globe was seen. Both sides retained a similar shape. A satisfactory functionality outcome in terms of improved extraocular muscle movement, and a satisfactory aesthetical outcome were achieved. Conclusion: The authors report the reduction of a globe displaced to the maxillary sinus following a fall and the reconstruction of the large defect left in the medial and inferior orbit.

Background: The purpose of this study was to evaluate the usefulness and safety of the anterosuperior deltoid splitting approach for fixation of displaced proximal humeral fractures by analyzing the surgical outcomes. Methods: Twenty-three patients who could be followed-up for at least 8 months after the treatment of displaced proximal humeral fractures through the anterosuperior deltoid splitting approach were enrolled. We evaluated the reduction of the fractures and surgery-related complications at the last follow-up using X-ray results and clinical outcomes comprising the University of California at Los Angeles (UCLA) scoring system and the Korean Shoulder Society (KSS) score. Results: At the last follow-up of patients treated using the anterosuperior deltoid splitting approach for internal fixation of proximal humeral fractures, we found 22 cases (95.6%) of bone union, a mean UCLA score of 28.3 (range, 15 to 34) and a mean KSS score of 82.1 (range, 67 to 95). Various surgery-related complications were noted; a case of varus malunion after fracture displacement, a case of nonunion, a case of delayed union, two cases of impingement, and a case of partial axillary nerve injury, which recovered completely through the follow-up. Conclusions: Plate fixation using the anterosuperior deltoid splitting approach could be another reliable option for treating displaced proximal humeral fractures.

Comminuted fracture of the distal end of the humerus in adults is very rare and difficult to treat. In operative treatment, an implant which can achieve accurate anatoraical reduction and rigid fixation is needed. But the pre­existing Y -shaped plate had wide and thick limbs and some problems in fixation for most distal humeral fractures. So we devised a modified plate which is more narrow and th1n and has a different hole distance and wing length (long lateral wing). The aim of the study was to evaluate the clinical result of this modified anatomical Y -plate. From 1991 to 1997, we treated 23 cases of distal humeral fractures using modified anatomical plate and the results were as follows. 1. Fracture type in 18 patients(78%) was C-type(C1,C2,C3) which were intraarticular and mostly displaced or comminuted. 2. Bony union was obtained in 22 patients(96%) through rigid fixation and observed radiologically at 3.5 months(2-6months) on the average. 3. In 23 patients, 19 patients(82%) showed satisfactory results after 34 months(6-73months) follow-up. So if the modified anatomical Y-plate is used in the treatment of distal humeral fracture, a satisfactory result can be obtained through a more accurate, easy, and rigid fixation than preexisting plate.

BACKGROUND. Mandibular displacement is a common complication of condylar fracture. In the mandibular displacement due to condylar fracture, it is difficult to restore both esthetics and function without using orthognathic surgery. CASE DESCRIPTION. This clinical report described a full mouth rehabilitation in the patient with bilateral condylar fractures and displaced mandible using bilateral sagittal split ramus osteotomy (BSSRO) and simultaneous dental implant surgery. Mandibular position was determined by model surgery through the diagnostic wax up and restoration of fractured teeth. The precise amount of the mandibular shift can be obtained from the ideal intercuspation of remaining teeth. CLINICAL IMPLICATION. Mandibular displacement by both condylar fractures can be successfully treated by orthognathic surgery. Determination of occlusal plane and visualization from diagnostic wax up are mandatory for mandibular repositioning of model surgery. Stable occlusion and regular recall check up are needed for long-term outcome.

Metatarsal head and neck fractures are injuries that often result from a direct blow of a heavy objects to the metatarsal head. The head is often impacted or displaced to the plantar aspect that if not treated may cause malunion which later induces painful plantar calluses. If the fracture fragment is large enough, closed reduction may be successfully performed, but when the fragment is small or closed reduction is unsuccessful, open reduction is needed. We present our reduction and fixation technique for the metatarsal head and neck fractures using antegrade intramedullary Kirschner wire (K-wire) without opening the fracture site or infringing the metatarsophalangeal (MTP) joint which allows immediate motion of the joint and partial weight bearing in a stiff soled shoe.

Background: Nasal bone fractures are managed by closed reduction within the 2-week period, and are managed by secondary correction after this time. There is little literature on the delayed reduction for nasal bone fractures beyond the 2-week duration. We report our experience with nasal fractures, which were reduced beyond this period. Methods: A retrospective review was performed for all patients who had undergone closed reduction of isolated nasal bone fracture. Patients were included for having undergone reduction of nasal bone fractures at or more than 2 weeks after the injury. Medical records were reviewed for demographic information, injury mechanism, fracture type, delay in treatment, and cause for delay. Postoperative outcomes were evaluated using computed tomography images. Results: The review identified 10 patients. The average reduction time was 22.1 days. Five of patients underwent reduction between days 15 and 20, and the remaining five patients underwent reduction between days 21 and 41. The postoperative outcomes were excellent in 8 patients and good in 2 patients. Conclusion: Outcomes were superior for nasal fractures with displaced end plates and multiple fracture segments. Our study results appears to support delayed reduction of isolated nasal fractures in the presence of factors that delay bony reunion.

Purpose: The aim of this study was to investigate the clinical cases of subcondylar fracture with intraoral approach. Material and Method: Fifteen patients with unilateral subcondylar fracture were treated in the department of oral and maxillofacial surgery, Kangdong Sacred Heart Hospital, College of Medicine, Hallym University between 2006 and 2007. Each patients was examined by computed tomography(CT) and panorama. 3D-CT taken when fractured segment was displaced and comminuted. Patients was done intermaxillary fixation to occlusal stability and prevent displacement of fractured segment before general operation. Open reduction and internal fixation(ORIF) accomplished under general anesthesia and used to intraoral approach. We examinated the state of occlusion, maximum opening. Evaluation of the state of occlusion was divided in patient`s subjective evaluation that compare pre-traumatic occlusion with postoperative occlusion, and estimator`s objective evaluation that use articulating paper. Examination was done at 2 weeks, 1, 3, 6 month postoperative by follow up. Result: The ORIF through intraoral approach was good in all patients. In the state of occlusion, all patients recovered pre-traumatic occlusion in 6 month postoperation. Maximum opening was gradually increased. In 3 month postoperative, maximum opening was excessed 40mm. Conclusion: Our study indicate that the intraoral approach is a good technique for subcondylar fracture. Intraoral approach prevent complication that facial nerve damage, scar formation caused by extraoral approach. So, we recommend intraoral approach when subcondylar fracture.
