Objectives : The purpose of this study was to investigate the maxillofacial injuries of the sports players' and analyzing the concerned factor. Methods : The subject in this study were 290 sports players' enrolled in Jeolla region. SPSS statistics program(Version 12.0) was used to analyzed the collectde data, Chi-square test and percentage were used as the analysis technique. Results : 1. It was found that 63.8% of all respondents ever experienced trauma in sport activities and 28.6% experienced maxillofacial trauma. 2. In terms of traumatic causality, it was found that most of our respondents attributed the biggest cause of maxillofacial trauma to 'sport activities.' 3. However, it was found that only 12.1% of all respondents gave correct answers to question items about good medical treatment for traumatic odontoptosis. 4. It was found that less than half of all respondents ever faced information on maxillofacial trauma. Conclusions : This finding suggests that it is required to build up current orientation programs about maxillofacial trauma for our sport players. The maxillofacial trauma of sport players' is a important factor that degenerate the quality of the oral health and bring about the change of life style.

False aneurysms(Pseudoaneurysms) and arteriovenous fistulas have only rarely been reported in the facial region. In this region the false aneurysm arises most frequently in the superficial temporal and facial artery, but other branches of the external carotid are sometimes involved, including the maxillary and lingual artery. False aneurysms can be occurred by blunt trauma that either laceration or rupture the full thickness of the arterial wall. The diagnosis of a false arterial aneurysm can be often made solely on the basis of physical examination. Angiography is helpful for conformation, for delineating the lesion and its vascular supply, and for ruling out the presence of associated vascular lesions such as arteriovenous fistulas. Ultrasonography may also be useful in delineating lesions that are not easily accessible for physical examination. Treatment of false aneurysms is excision, ligation, and arterial embolization. This is a case of false aneurysm of the lingual artery after facial trauma caused by traffic accident. The lesion was successfully treated by embolization and ligation of the lingual and facial branches of the external carotid artery.

Ankylosis of joint is defined as limited movement due to infection, trauma, or surgical procedure. A 59-year-old female with a chief complaint of limited movements during mouth opening had a positive history of trauma to her right TMJ area about 5 years ago. From that time, progressive mouth opening limitation and intermittent pain have occurred. At the time of admission the patient showed mandibular deviation to the right side during mouth opening, with a maximum opening limited to 5 mm. On plain radiographs, right condylar enlargement and joint space reduction by newly formed bony tissues were observed. CT scans showed right condylar enlargement, cortical sclerosis, and thickening of the condyle, articular fossa and articular eminence.

Plexiform neurofibroma is a rare benign tumor and a special subtype of neurofibromatosis 1. This report is a literature review with a case of patient with facial hemorrhage observed at the site of neurofibroma removal in the right lower face due to minor trauma. Through PubMed search, using terms ((facial hematoma) OR (facial bleeding)) AND (neurofibromatosis), 86 articles were identified, and five related articles (six patients) were finally selected. Of the six patients, two had previously undergone embolization. However, as a result, all patients received open surgery to remove hematomas. The hemostatic methods mentioned were vascular ligation (five patients), hypotensive anesthesia (two patients), and postoperative blood transfusion (four patients). In conclusion, spontaneous or minimally traumatic bleeding is possible in neurofibromatosis patients. In most cases, it can be resolved by vascular ligation under hypotensive anesthesia. Optionally, prior embolization and supplementary tissue adhesive may be used.

Objectives: Joint injuries frequently lead to progressive joint degeneration that causes articular disc derangement, joint inflammation, and osteoarthritis. Such arthropathies that arise after trauma are defined as post-traumatic arthritis (PTA). Although PTA is well recognized in knee and elbow joints, PTA in the temporomandibular joint (TMJ) has not been clearly defined. Interestingly, patients experiencing head and neck trauma without direct jaw fracture have displayed TMJ disease symptoms; however, definitive diagnosis and treatment options are not available. This study will analyze clinical aspects of PTA in TMJ and their treatment outcomes after joint arthrocentesis and lavage. Materials and Methods: Twenty patients with history of trauma to the head and neck especially without jaw fracture were retrospectively studied. Those patients developed TMJ disease symptoms and were diagnosed by computed tomography or magnetic resonance imaging. To decrease TMJ discomfort, arthrocentesis and lavage with or without conservative therapy were applied, and efficacy was evaluated by amount of mouth opening and pain scale. Statistical differences between pre- and post-treatment values were evaluated by Wilcoxon signed-rank test. Results: Patient age varied widely between 20 and 80 years, and causes of trauma were diverse. Duration of disease onset was measured as 508 post-trauma days, and 85% of the patients sought clinic visit within 2 years after trauma. In addition, 85% of the patients showed TMJ disc derangement without reduction, and osteoarthritis was accompanied at the traumatized side or at both sides in 40% of the patients. After arthrocentesis or lavage, maximal mouth opening was significantly increased (28-44 mm on average, P<0.001) and pain scale was dramatically decreased (7.8-3.5 of 10, P<0.001); however, concomitant conservative therapy showed no difference in treatment outcome. Conclusion: The results of this study clarify the disease identity of PTA in TMJ and suggest early diagnosis and treatment options to manage PTA in TMJ.

This is a retrospective clinical study on 2,955 patients who had visited the Emergency Room of Sang-gye Paik Hospital and then been treated in the Department of Oral and Maxillofacial Surgery during recent 4 years from Aug. 2002 to Dec. 2006. The obtained results were as follows. The total number of patients was 2,955 and the ratio of male to female was 1.72:1. The age distribution peak was the 1st decade (30.8%), followed by the 3rd decade (14.3%) and the 4th decade (14.0%). Trauma (62.3%) was the most frequent cause in dental emergency patients, pulpitis (13.0%) and infection patients were next in order of frequency. In trauma patients group, facial bone injury, tooth injury, soft tissue injury were included and soft tissue injury group was most prevalent, followed by tooth injury group and facial bone group. In total patient, the ratio of admission was 3.5%. We obtained the results of the distribution of primary emergency care in the traumatic injury, causal distribution of the jaw fracture, distribution of related medical department in multiple associated injuries, distribution of emergency care in infection, causal distribution and control methods of oral bleeding, distribution of TMJ disorder. The trauma patient group was major in the dental patients who had visited the emergency room, but other various groups were included. So we should analyze the pattern and the variation of the dental emergent patient to provide the proper treatment.

Return of facial nerve function is important in patients with facial nerve paralysis by trauma. Sometimes, delay in diagnosis of facial nerve paralysis make recovery of facial nerve function difficult. Traumatic facial palsy mostly occur after temporal bone fracture in unilateral. Temporal bone fracture after head trauma are divided into the three group; longitudinal fracture, transverse fracture and mixed fracture. The most common symptoms are hearing impairment, bloody otorrhea, loss of consciousness and facial nerve paralysis. The early care of temporal bone fracture involves facial nerve paralysis. And there has been many discussion and study in the treatment of the immediate or delayed facial palsy ; examply, surgical approach, time and methods. We have managed a patient with unilateral facial nerve paralysis after longitudinal temporal bone fracture in mastoid process and conservative facial nerve decompression was performed. We have obtained good result and report this case with review of literatures.

Clinical features of masticator-space abscess (MSA) are very similar to those of parotitis or temporomandibular disorder (TMD), making early differential diagnosis difficult. Local causes of MSA include nerve block anesthesia, infection after tooth extraction, and trauma to the temporomandibular joint (TMJ); the systemic cause is immunodeficiency. Odontogenic causes account for most etiologies, but there are also unusual causes of MSA. A 66-year-old male patient visited the emergency room (ER) presenting with left-side TMJ pain three days after receiving an acupressure massage. He was tentatively diagnosed with conventional post-trauma TMD and discharged with medication. However, the patient returned to the ER with increased pain. At this time, his TMD diagnosis was confirmed. He made a third visit to the ER during which facial computed tomographic (CT) images were taken. CT readings identified an abscess or hematoma in the left masticator space. After hospitalizing the patient, needle aspiration confirmed pus in the infratemporal and temporal fossa. Antibiotics were administered, and the abscess was drained through an incision made by the attending physician. The patient's symptoms decreased, and he was discharged.

Actinomycosis is an infrequent chronic infection regarded as the most misdiagnosed disease by experienced clinicians. The Office of Rare Diseases at the National Institute of Health has also listed this disease as a "rare disease." This article presents a case report of actinomycosis of the alveolus with unusual clinical features but a successful resolution. It also states the importance of biopsy of deceptive inflammatory lesions that do not respond or recur after conventional treatment modalities.
