Out of all oral malignant tumor, malignant lymphoma occurs in only 3.5%. Especially, most of the primary malignant lymphomas, which occur in the head & neck region are high-grade diffuse large B-cell lymphoma and mucosa-associated lymphoid tissue (MALT) marginal zone B-cell lymphoma is very rare. In the head & neck region, malignant lymphoma is reported to occur in the thyroid, salivary gland, trachea, larynx, orbital lobe and the Waldeyer’s ring. Among the Waldeyer’s ring, palatal tonsil is reported to be the most common region, but, only 1 case report was published in Korea. Until now, there were no case reports of MALT lymphoma that occurred in the tongue. The purpose of this case report is to report and discuss on a case of MALT lymphoma of the tongue.

Bisphosphonates (BPs) are a class of agent used to treat patient with osteoporosis or malignant bone metastases. BPs can be categorized into 2 groups: nitrogen-containing and non-nitrogen containing. Nitrogen-containing BPs are considered to have more toxicity. Despite their clinical benefits, bisphosphonate-related osteonecrosis of jaw(BRONJ) is a significant complication to patients receveing these drugs. Since the first description of BRONJ in 2003 by Marx, the number of reports on BRONJ has been rapidly increasing. BRONJ is considered as an emerging problem in oral & maxillofacial surgery. Generally, osteonecrosis in the maxilla is rare, however BRONJ is found both in the maxilla and the mandible. This is an important feature of BRONJ compared to common infectious osteomyelitis of the jaw. Growing number of case reports, suggest that bisphosphonate therapy may cause exposed, necrotic bone. BRONJ has simillar features compared to IORN (infected osteoradionecrosis). BRONJ has meaningful features established through the interestigation on histopathologic and radiographic findings. These features have an impact on treatment plan and prognosis. This presentation contemplates on features of histopathologic and radiographic findings in bisphosphonate-related osteonecrosis of the jaw.

The orthognathic surgical procedures are performed for the correction of abnormalities of the facial skeleton that are present from the birth or arise during growth or acquired secondarily during lifetime. We would prefer to summarize some commonly used techniques to correct the dentofacial deformities. Even we have described all these techniques at their popular time with our orthodontist colleagues; skeletal anchor systems, some basic interdental osteotomies, or complex mechanics that are applying orthopedic corrective forces are currently being used by the orthodontists rather than surgeons. Le Fort I osteotomy in maxilla and Bilateral sagittal split ramus osteotomies (BSSRO) in mandible are commonly used techniques to solve the deformity problems of the facial skeleton; therefore, the scope of this paper is going to be including my personal experience and some technical details with Le Fort I and SSRO.

Patients undergoing orthodontic treatment are more likely to have apical root shortening. Many literatures showed the etiologic factors were complex and multifactorial. It appears that external apical root resorption results from a combination of patient-related risk factors such as previous history of root resorption, genetic influences and systemic factors and orthodontic treatment-related factors like treatment duration, magnitude of applied force, direction of tooth movement, amount of apical displacement, method of force application, type of appliance, treatment technique and so on. We could encounter the patients having the short teeth root and the poor periosteum in a case that much maxillary setback be needed, such as bimaxillary protrusion or skeletal class II. The anterior segmental osteotomy (ASO) has been known that this could complement the possibility of external apical root resorption and buffer the periodontal problems, so it could be the choice of treatment. But the studies about the efficacy of ASO in aspects of preserving the root are deficient. So in this study, we compared the amount of root resorption after orthodontic procedure between patients group who had been taken a conventional orthodontic and patients group in whom ASO had been included in orthodontic treatment procedure.

The advent and wide use of antibiotics have decreased the incidence of deep neck infection. When a deep neck infection does occur, however, it can be the cause of significant morbidity and death, resulting in airway obstruction, mediastinitis, pericarditis, epidural abscesses, and major vessel erosion. In our clinic, a patient with diffuse chronic osteomyelitis of mandible and fascial space abscess and necrotic fasciitis due to odontogenic infection at the time of first visit came. We successfully treated the patient by early diagnosis using contrast-enhanced CT and follow up dressing through the appropriate use of radiographic images.

Purpose: The purpose of this study was to assess the height change of graft bones in a long-term follow-up after maxillary sinus floor augmentation procedures and compare the difference between xenografts and synthetic material. Materials and Methods: The subjects comprised 28 patients (62 implants) who underwent sinus floor augmentation using the lateral window technique and staged implantation. Panoramic radiographs of the 28 patients were collected immediately after implantation and at follow-up. Results: Changes in the grafted bone height showed a statistically significant decreasing tendency with time in both groups. However, there was no significant difference between the groups. Conclusions: Both xenogeneic bones and synthetic bone substitute materials were resorbed with time but maintained their shape and properties after 10 years. Therefore, both materials are suitable for sinus augmentation and biphasic calcium phosphate, a synthetic bone substitute, has shown predictable stability in sinus augmentation during long-term follow-ups.

Objectives: During Le Fort I osteotomy, the separation of the pterygomaxillary junction (PMJ) is a difficult procedure for most surgeons because it is invisible. In this process, damage to the posterior structures constituting the sinus or those adjacent to it, including the maxillary sinus posterior wall and pterygoid plate, may occur. We would like to investigate the effects of this on the inside of the maxillary sinus after surgery and whether there are complications. Materials and Methods: One-hundred patients who underwent Le Fort I osteotomy from 2013 to 2020 using cone-beam computed tomography images were classified into two groups (clean-cut type and fractured type) according to the PMJ cutting pattern. In addition, the mucosal thickness in the maxil-lary sinus was divided into preoperative, postoperative three months, one year, and the change over the course of surgery was evaluated retrospectively. Results: Of the total 100 cases, the clean-cut type numbered 28 cases and the fractured type totaled 72 cases. Among the fracture types, part of the si-nus wall and the pterygoid plate were broken in 69 cases, and the maxillary sinus posterior wall was detached in three cases. There was no statistically significant difference in sinus mucosal thickening between the clean-cut type and fractured type of the PMJ, three months and one year after surgery between the two groups. However, there was a significant difference in sinus mucosal thickness at postoperative one year in the case where a partial detachment of the maxillary sinus posterior wall occurred compared to not. Conclusion: Even if there is some damage to the structures behind the PMJ, it may not be reasonable to spend some time on the PMJ separation pro-cess considering the overall postoperative complications, if there is no significant difference inside the sinus, or increased probability of postoperative complications.
