ABSTRACT
Septic arthritis of the temporomandibular joint (TMJ) is a rare disease. The most common symptoms of this disease are acute malocclusion, limited mouth opening, swelling, and tenderness of affected TMJ. These symptoms are often confused with internal derangement of the articular disc, rheumatoid arthritis, retrodiscitis, or osteoarthritis. Therefore, differential diagnosis by image examination is required. Usually, antimicrobial treatment and surgical drainage by needle aspiration, arthroscopy, or arthrotomy are effective treatment approaches. In this study, a patient who was diagnosed with septic arthritis was treated with arthrocentesis and antibiotics without significant complications. We present a case report with a review of the literature.

In the Department of Oral and Maxillofacial Surgery, patients with trismus can be easily identified. If the cause of trismus is infection of the masticatory space near the pterygoid plexus, the possibility of cavernous sinus thrombosis should be considered. We report the case of a patient who presented with limited mouth opening and progressed to cavernous sinus thrombosis, along with a review of the relevant literature.

We experienced a patient of subcondylar fracture who had a squared contour of the lower face with prominent angle of the mandible and masseter hypertrophy. Our patient was increasingly seeking esthetic improvement of the lower third of the face. But she did not want multi-stage operations. Thus, we decided and performed a one-stage mandibular angle ostectomy with fracture management. We have a stable and esthetic result simultaneously despite fractures of the fixation plates during follow-up period, so report a case.

Nasotracheal intubation should be performed in patients with jaw fractures because maxillomandibular fixation is required. However, when there are concomitant fractures of the nose and facial bones, an intubation tube positioned at the nose makes it difficult to perform an intricate surgery. In order to overcome these problems, a variety of ways to change the position of the tube have been introduced. We describe a simple technique of switching the tube from a nasal to oral position, which was easily executed in a patient with concomitant nasal and mandibular fractures, accompanied by a literature review.

OBJECTIVES: We compared resorbable plates with titanium plates for treatment of combined mandibular angle and symphyseal fractures. MATERIALS AND METHODS: Patients with mandibular angle and symphysis fractures were divided into two groups. The control (T) group received titanium plates while the experimental (R) group received resorbable plates. All procedures were carried out under general anesthesia using standard surgical techniques. We compared the frequency of wound dehiscence, development of infection, malocclusion, malunion, screw breakage, and any other technical difficulties between the two groups. RESULTS: Thirteen patients were included in the R group, where 39 resorbable plates were applied. The T group consisted of 16 patients who received 48 titanium plates. The mean age in the R and T groups was 28.29 and 24.23 years, respectively. Primary healing of the fractured mandible was obtained in all patients in both groups. Postoperative complications were minor and transient. Moreover, there were no significant differences in the rates of various complications between the two groups. Breakage of 3 screws during the perioperative period was seen in the R group, while no screws or plates were broken in the T group. CONCLUSION: Resorbable plates can be used to stabilize combined mandibular angle and symphysis fractures.

OBJECTIVES: To compare the clinical and radiological outcomes after closed reduction (CR) and open reduction and internal fixation (ORIF) in the management of subcondylar fractures. MATERIALS AND METHODS: Forty-eight patients presenting with subcondylar fracture between January 2010 and March 2013 were evaluated retrospectively. Fifteen patients were treated with CR and 33 patients with ORIF. The clinical and radiologic parameters were evaluated during follow-up (mean, 7.06 months; range, 3 to 36 months). RESULTS: In the CR group, no patients had any problems with regard to the clinical parameters. The average period of maxillomandibular fixation (MMF) was 5.47 days. The preoperative average tangential angulation of the fractured fragment was 3.67degrees, and loss of ramus height was 2.44 mm. In the ORIF group, no clinical problems were observed, and the average period of MMF was 6.33 days. The preoperative average tangential angulation of the subcondylar fragment was 8.66degrees, and loss of ramus height was 3.61 mm. CONCLUSION: CR provided satisfactory clinical results, though ORIF provided more accurate reduction of the fractured fragment. So there is no distinct displacement of fractured fragment, CR should be selected than ORIF because of no need for surgery.

OBJECTIVES: Bisphosphonates (BP) are widely used in medicine for inhibiting bone resorption; however bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a major side effect of BP. To date, there have been no specific reports on the incidence of BRONJ among Koreans. This study investigated the preliminary results from a nationwide survey of BRONJ in the Departments of Oral and Maxillofacial Surgery (OMFS) at individual training hospitals. MATERIALS AND METHODS: A total of 15 OMFS departments (10 from dental schools, 4 from medical schools, and 1 from a dental hospital) participated in a multi-centric survey. This study assessed every BRONJ case diagnosed between January 2010 and December 2010. The patient age and BP type were evaluated. RESULTS: A total of 254 BRONJ cases were collected. The majority of BRONJ cases were associated with oral BP therapy, while 21.8% of the cases were associated with intravenous administration. Alendronate was the drug most frequently related to BRONJ (59.2% of cases), followed by risedronate (14.3%) and zolendronate (17.0%). The average age of BRONJ patients was 70.0+/-10.1 years, with a range of 38-88 years of age. With the number of BP patients in Korea reported to be around 600,000 in 2008, the estimated incidence of BRONJ is at least 0.04% or 1 per 2,300 BP patients. CONCLUSION: The results suggest that the estimated incidence of BRONJ in Korea is higher than the incidence of other countries. Future prospective studies should be carried out to investigate the exact epidemiological characteristics of BRONJ in Korea.

Focal osteoporotic bone marrow defect (FOBMD) is a radiolucent area corresponding to the presence of hematopoietic tissue rarely found in the jaws. FOBMD is most commonly located in the mandibular edentulous posterior area of a middle-aged female. From November 2011 to November 2012, we experienced three cases involving removal of implants that had accidentally fallen into the FOBMD area. All patients happened to be female, with a mean age of 54 years (range: 51-60 years). One case involved hypoesthesia of the lower lip and chin, while two cases healed without any complication. Displacement of an implant into the FOBMD area is an unusual event, which occurs rarely during placement of a dental fixture. The purpose of this study was to report on three cases of FOBMD and to provide a review of related literature.

This paper reports two cases of schwannomas arising from the oral cavity. One is an intraoral ancient schwannoma located at the left cheek, which evolved over a period of 13 years. The tumor was a well-demarcated buccal mass, which was located in the left lower first premolar area, with an obliterated the buccal vestibule, leaving the overlying mucosa intact. The second case was a central intraosseous schwannoma located from the left lower 1st molar periapical area to the left 3rd molar periapical area. Pathologically, the first mass was composed of the spindle shaped tumor cells with wavy nuclei beneath the fibroconnective tissue of the gingiva but second case mass was not. Occasional nuclear pleomorphism was observed but mitosis or necrosis was absent. There were Antoni A and B areas along with strong, diffuse staining with the S-100 protein. Ancient schwannomas were diagnosed. Schwannoma is a slow-growing benign tumor, and an ancient schwannoma that shows cellular atypism is a variant of a schwannoma caused by purely degenerative changes. To date, only limited cases of ancient schwannomas in the oral cavity have been reported.

Carcinoma ex pleomorphic adenoma is transformed at the incidence of 1-20% in pleomorphic adenoma and frequently recurred. It accounts for 10% of all malignant salivary tumors and its average age of occurrence is 60s. It will present in a large, long-standing pleomorphic adenoma or in one that was previously treated but has recurred. According to cell composition in malignant cell carcinoma, and clear cell adenocarcinoma. Most (75%) occur in parotid gland, while about 20% occur in the minor gland of the oral mucosa. The metastasis rate to regional lymph node is about 25%, and to distant organs about 33% and the 5-year survival rates are 40%. Though the treatment of the carcinoma ex pleomorphic adenoma is not established, it is treated ideally with and extensive resection, neck dissection, postoperative radiotherapy, and chemotherapy. When occurred in parotid gland, facial paralysis is reported. With a review of literatures, we report a case of carcinoma ex pleomorphic adenoma which operated with total parotidectomy and supraomohyoid neck dissection.

In 1974, Casson et. al. reported midfacial degloving approach to repair the midfacial bone fracture. After then, this approach has been used frequently to treat the lesions on nasal cavity, nasopharynx, facial plastic surgery and midfacial trauma. Midfacial degloving approach consists of 1) bilateral sublabial incision 2) complete transfixion incision/ septocolumellar incision 3) bilateral intercartilaginous incision 4) bilateral pyriform aperature incision. This approach provides proper access for midfacial bone structure without facial scar but has post-operative complications such as transient epistaxis, infraorbital nerve paresthesia and nasal crust. We treated three patients using midfacial degloving approach to correct traumatic deformity in midface area. In two patients, rhinoplasty with autogenous rib graft was done simultaneously. So we report these cases with review of literatures.

A dentigerous cyst is an epithelium-lined sac that surrounds the crown of an unerupted tooth or odontoma. And the most common sites of this cyst are the mandibular and maxillary third molar and maxillary cuspid areas. Clinically, expansion of bone with subsequent facial asymmetry, extreme displacement of teeth, severe root resorption of adjacent teeth and pain are all possible sequelae of this cyst. The standard treatment for a dentigerous cyst is enucleation and extraction of the involved tooth. But in large cysts, this can lead to functional, cosmetic and psychologic consequences to the patients. So recently, more conservative methods are used. We report 5 cases of dentigerous cysts in pediatric patient which were treated by a conservative approach, By this methods, we can preserve teeth and guide eruption of the teeth which are involved in cystic area.
