Malignant Melanoma refers to a malignant neoplasm of melanocytes. Primary malignant melanoma of oral cavity is rare. Most frequent site of primary oral malignant melanoma are palate & gingiva. We have experienced 2 cases of malignant melanoma of the mouth. In one case, we performed wide surgical excision which was followed by chemotherapy with DTIC. In the other case, performed wide surgical excision only. There is no evidence of recurrence or of metastasis of the lesions 22 months, 12 months after operation, respectively.

In the treatment of maxillary lesion including a maxillary sinuses, most of oral and maxillofacial surgeons have used the vestibular incision or the Weber-Fergusson incision. However, the vestibular incision has disadvantage which it provides a rather limited exposure and the Weber-Fergusson incision leaves visible scar in the midface. Furthermore, because the scar is confined on unilateral side only, the technique is hesitated to apply especially in children, younger patients and women. Since Casson first introduced midfacial degloving technique, this approach has been used frequently to treat the lesion on nasal cavity, nasopharynx, skull base and paranasal sinuses by ENT surgeons. But, we think this technique can be used usefully in oral and maxillofacial regions. So, we experienced favorable results which it provided a proper exposure, no visible facial scar and it could be used on bilateral midfacial lesions.

The osteoradionecrosis of the mandible can be a serious complication of radiotherapy for malignancies of the head and neck. The cause and pathogenesis of osteoradionecrosis are unclear and anecdotal. There are various treatment-, patient- and tumor-related risk factors on development of osteoradionecrosis. The treatment of osteoradionecrosis relies on conservative measures (antibiotics, debridement, irrigation and HBO) and surgical measures (sequestrectomy, marginal resection and segmental resection with or without reconstruction). But the indications are not defined. We present the two cases of patients who were not controlled by conservative treatment but good-resulted by surgical treatment.

The changes of the microorganism composition after therapeutic radiation for oral cancer patients are not well known and the long-term follow-up data are not reported. To obtain basic data for understanding of pathogenesis and prevention and treatment of dental caries and mucositis occuring after radiation therapy, 7 of the oral cancer patients presented at the Seoul National University Oral & Maxillofacial Department between 1997 and 1998 whose treatment plan included radiation therapy were recruited to investigate the changes in bacterial composition(total aerobic count, Candida, Staphylococci, Lactobacilli, S. mutans, and S. salivarius (mitis, sanguis)) of the saliva before, during, and after radiation therapy. The basic data obtained from this study on identification and composition change of the bacteria in saliva of patients treated with radiation therapy can be used (1) as a reference for deciding on the ideal anti-microbial spectrum of the oral rinsing agent to be used in patients treated with radiation therapy for malignant tumor of the head and neck region. (2) to enhance the understanding of increase of opportunistic infection after immunochemical changes of the saliva and its relation to specific bacterial infection. (3) as a reference in prescribing prophylactic antibiotics in immunodepressed patients after radiation therapy.

Purpose: Patients usually suffer from pain and discomfort after oral surgery and their consumption of food is severely affected. Accordingly, the patients' quality of life reduce significantly. The aim of this study was to analyze patient satisfaction on the nutritional supplement drinks following periodontal surgery. Materials and Methods: Total 90 patients who underwent periodontal surgery were recruited and commercially available nutritional drinks were provided. Group I received two bottles per each meal for 2 days, Group II had one bottle per each meal for 3 days, and Group III had no drinks. The survey for the patient-reported outcome measures (PROMs) were given at the next visit for the removal of sutures. Results: The result of PROMs showed the nutrition drink was easy to intake, appeared to help the healing and can be a satisfying supplement for the meals. Conclusion: Nutritional drinks appeared to help the healing after periodontal surgeries and supported the food intake. Also, it was helpful for the patients in nutritional supply and psychological stability.

To restore a tooth with a fracture line extending below the marginal bone level, a surgical crown lengthening procedure accompanied by ostectomy could be considered to expose the fracture line and reestablish the biologic width. However, this procedure could lead to esthetic failure, especially in the anterior teeth. Therefore, orthodontic extrusion, which elevates the fracture line from within the alveolar socket without sacrificing the supporting bone and gingiva, is recommended. This technique allows for the proper placement of the crown on a sound tooth structure, with the reestablishment of the biologic width. Alternatively, surgical extrusion is an one-step procedure that is simpler and less time-consuming than orthodontic extrusion; placing and adjusting the orthodontic appliance does not require multiple visits. This study presents successful restoration in 2 cases with a crown-tooth root fracture of the maxillary central incisor treated using a multidisciplinary approach through orthodontic extrusion or surgical extrusion followed by successful restoration.

Oromandibular dystonia is a focal neurological movement disorder characterized by involuntary sustained and often painful muscle contraction, usually producing repetitive movements or abnormal positions of the mouth, jaw and.or tongue. Patients suffering from oromandibular dystonia often experience difficulties in chewing, swallowing and speaking, resulting from the impairment of mandibular movements. At present there is no etiologic treatment for oromandibular dystonia, because the pathophysiology of primary and focal dystonia is still incompletely understood. Many treatments such as medication, behavioral therapy, surgery are suggested to decrease the involuntary movements. But these success rates are relatively low and they have a lot of complications. many studies suggested that chemodenervation with botulinum toxin is the most effective treatment for oromandibular dystonia. We reported the 2 cases which were treated oromandibular dystonia with botulinum toxin and reviewed the orofacial movement disorders(especially oromandibular dystonia) and botulinum toxin treatment for oromanfibular dystonia.

Background and Objectives The purpose of the present study was to evaluate the usefulness of a posterior-based buccinator myomucosal flap (the Bozola flap) for the reconstruction of oral cavity defects after tongue cancer resection. Subjects and Method Fifteen patients who underwent from 2014 to 2016 reconstruction of the oral cavity with a Bozola flap after surgical management of tongue cancer were enrolled in the study. Patient characteristics, surgical outcomes, and complications associated with the Bozola flap were evaluated. Results The flap was successfully harvested and transferred in all patients. The mean flap harvesting time was 25.3 min. The donor site was closed primarily in 14 patients, and a buccal fat pad flap was used in one patient. Although partial necrosis of the flap occurred in two patients, no other major complications were noted. Conclusion The results of this study demonstrate that the Bozola flap is a good option for reconstruction of moderate sized oral cavity defects in tongue cancer patients.

Malignant oral tumors occurred in the oral cavity. They were thought to result from the other primary tumors through hematogenous metastasis. Primary tumors were unusually gall bladder tumor and pancreatic tumor. Biopsy was performed and these specimens were similar to those of the primary sites histologically and clinically. Diagnoses were adenocarcinomas metastatic from the primary tumors. They did not reveal the bony changes, only soft tissue masses.

Sturge-Weber syndrome is a rare nonhereditary developmental condition that is characterized by a hamartomatous vascular proliferation involving the tissue of brain and face. The clinical features are characterized by port wine nevus following one or more divisions of trigeminal nerve, ocular involvement and neurologic involvement such as epilepsy, mental retardation, and contralateral hemiplegia. Oral manifestations include unilateral blood vessel expansion of the oral mucosa, vascular hyperplasia of gingiva, pyogenic granuloma-like massive hemangiomatous proliferation of oral mucosa, macrodontia, ipsilateral macroglossia, blood vessel anomaly of maxilla or mandible and abnormal tooth eruption sequence. This case report is about 11-year-old Sturge-Weber syndrome patient presented port wine nevus on the face, venous malformation on soft plate and buccal mucosa. In this case we performed simple extraction of several deciduous teeth and periodic oral hygiene management. If a patient with Sturge-Weber syndrome has to undergo dental surgery in affected areas of the mouth, great care must be taken to prevent severe hemorrhage.
