Sodium hydroxide or caustic soda is a corrosive agent that can cause extensive damage to the oral mucosa, lips, and tongue when ingested either accidentally or intentionally. These injuries include microstomia, shallow vestibule, ankyloglossia, speech impairment, loss of teeth and impairment in facial expression. In the present article, we report a unique case of tongue adhesion to the mouth floor and its surgical management in a 66-year-old female patient, who had a history of caustic soda ingestion.

Management of maxillofacial trauma includes primary care, in which diagnosis and management of dentoalveolar injury play a vital role. Due to the impact sustained during a maxillofacial injury (whether direct or indirect), dentoalveolar injuries can occur, leading to fracture and displacement of teeth and associated alveolar bone into the surrounding soft tissues and associated structures, such as the maxillary sinus, nasal cavity, upper respiratory tract, tracheobronchial tree, or gastrointestinal tract. Undiagnosed displaced teeth may cause complications such as airway obstruction. This paper reports a case of displaced teeth in the nasal cavity and gastrointestinal tract and highlights the management protocol for displaced teeth secondary to maxillofacial trauma.

Clear cell odontogenic carcinoma (CCOC), a rare tumor in the head and neck region, displays comparable properties with other tumors clinically and pathologically. In consequence, an incorrect diagnosis may be established. A 51-year-old male patient who was admitted to the Department of Oral and Maxillofacial Surgery at Pusan National University Dental Hospital was initially diagnosed with ameloblastoma via incisional biopsy. However, the excised mass of the patient was observed to manifest histopathological characteristics of ameloblastic carcinoma. The lesion was ultimately diagnosed as clear cell odontogenic carcinoma by the Department of Oral Pathology of Pusan National Dental University. Therefore, segmental mandibulectomy and bilateral neck dissection were performed, followed by reconstruction with fibula free flap and reconstruction plate. Concomitant chemotherapy radiotherapy was not necessary. The patient has been followed up, and no recurrence has occurred 6 months after surgery.

Mongolia is a huge, landlocked, middle-Asian country bordering Russia in the north, and China in the south. Mongolia was under socialism from 1921 to 1990, and its political system has started moving toward capitalistic democratism in 1990. The history of the Mongolian Oral & Maxillofacial Surgery can be divided into four periods; the incipient period($1956{\sim}1971$), the period of early development($1971{\sim}1981$), the period of active development($1981{\sim}1991$), and the period of reformation($1991{\sim}$). Mongolian Oral & Maxillofacial Surgery had been developed by the cooperation of Soviet Union and Eastern European countries before the 1990s, but the role of Korea, Japan, and western countries has been increasing from the 1990s. In Mongolia Oral & Maxillofacial Surgery is well recognized to the people and is considered as one of the specialized medical field. There are specialized departments of Oral & Maxillofacial Surgery in State Central Hospital, Child & Maternal Research and Clinical Center, and Oncology Center in Ulaanbaatar. Now, the basic knowledge and surgical technique of the Mongolian Oral & Maxillofacial Surgeons are satisfactory. But because of the difficult social and economic situation, there is a shortage of surgical instruments and materials, and acquirement of new knowledge is not easy. In 1998 the Mongolian Association of Oral & Maxillofacial Surgeons was established and its members want to have international relationship to keep up with the new medical information. Mongolia and Korea have ethnic, linguistic and cultural similarity, so the interchange and cooperation between Mongolian and Korean Oral & Maxillofacial Surgeons are recommended to make a beautiful one-world.

The purpose of this study is to report on five cases treated with bone graft using recombinant human bone morphogenetic protein-2 (rhBMP-2) on jaw defects after cyst enucleation. We performed bone graft with BMP (rhBMP-2+${\beta}$-tricalcium phosphate/hydroxyapatite) wrapped with a collagen sponge on jaw defects after cyst enucleation. Postoperative panoramic radiographs were taken periodically. After 1 to 12 months, bone remodeling was observed in the jaw defect area. In our cases, there were few signs or symptoms of recurrence of the cyst during the follow-up period.

Objectives: The aim of this study was to evaluate the journal category "oral surgery" in Scopus and in the Science Citation Index Expanded (SCIE). Materials and Methods: The Journal of Oral and Maxillofacial Surgery (JOMS), The Journal of the Korean Association of Oral and Maxillofacial Surgeons (JKAOMS), and The Journal of Prosthodontic Research (JPR) were selected from the Scopus list of journals as oral surgery journals. Maxillofacial Plastic and Reconstructive Surgery (MPRS) was selected from PubMed as a Scopus oral surgery title. From these titles, 10 recently published articles were collected and used for reference analysis. Results: The percentage of citations from oral surgery journals was 26.7%, 24.5%, and 40.1% for JKAOMS, MPRS, and JOMS, respectively. In total, 1.1% of JPR's citations were from oral surgery journals and significantly fewer from other journals (P<0.001). The percentage of citations from dentistry journals excluding oral surgery journals was 11.9%, 34.4%, and 15.8% for JKAOMS, MPRS, and JOMS, respectively. For JPR, 80.6% of citations were from dentistry journals and significantly more were from other journals (P<0.001). Conclusion: Selected samples revealed that JPR is incorrectly classified as an oral surgery journal in Scopus. In addition, the scientific interaction among JKAOMS, MPRS, and JOMS was different to JPR in the reference analysis.

Maxillary sinusitis is an infectious disease which can arise from odontogenic etiology and a maxillary osteomyelitis can spread into the sinus and consequently develop maxillary sinusitis. In this case report, a mid eighty's lady was diagnosed as BRONJ with maxillary sinusitis as a complication. The patient was managed successfully in collaboration with a endocrinologist. Through serial follow-up of serum CTX, we could decide the timing of surgical intervention.

Botulinum toxin (BTX) has various therapeutic indications: bruxism, square jaw, facial wrinkle, oral ulcer and maxillofacial pain, etc. In this paper, we will discuss the effectiveness of using BTX in dental implant surgery and orthognathic and orthodontic treatment. We summarized the clinical application of botulinum toxin in the maxillofacial field at the finale.

For the successful placement of dental implants, adequate alveolar bone height and width are required. Alveolar distraction osteogenesis is an effective method that resolves insufficient alveolar bone height for dental implant placement, and thus has been clinically applied with satisfactory results. But, minor and major problems may occur during the treatment. In the following report, we studied for such problematic cases. The problems are as follows: 1) sharp edges of the transport segment, 2) infection, 3) soft tissue dehiscence, 4) limitation of distraction, 5) numbness, 6) insufficient bone formation. But, most of them were answered by simple solutions and did not jeopardize the final outcomes. Distraction osteogenesis can be considered a safe and predictable procedure for lengthening the alveolar bone.

Treatment of infected mandibular fracture is confronted with various difficult problem, e.g. nosocomial wound infection, non-union of fracture, osteomyelitis. Recently, nosocomial infection has become a major health problem because of excessive morbidity, personal distress, and cost. Frequently, isolated causative microorganisms of nosocomial infection were staphylococcus aureus, pseudomonas aeruginosa, klebsiella species. The various manifestation of the disease related to the pathogenesis and the clinical course tend to give a bad prognosis after operation. This is a report of case that post-operative infected mandibular fracture in 53-year-old man was not healed even through aggressive I & D and antibiotic treatment.
