Segmental mandibulectomy causes severe functional disability and cosmetic problem. Many methods of reconstruction have been used but none of these procedures provides the ideal solution. There has been increased interest in the possibility of preserving a portion of the mandible and still carrying out a adequate tumor resection. We experienced four cases of marginal with sagittal mandibulectomy in patients with floor of mouth. buccal. and soft palate carcinoma, and sagittal mandibulectomy in 8 patients with tonsillar carcinoma and a case of marginal mandibulectomy in tonsillar cancer patient. In all cases mandible facing the tumor were successfully resected and repair of the mandible. postoperative facial contour were satisfactory. We think. that these sagittal procedures are oncologically sound in its removal of tumor. biomechanically secure and maximize postoperative rehabilitation while maintaining the normal contour of the face.

Mucoceles are common benign cystic lesions of the oral cavity that develop following extravasation or retention of mucous material from the major or minor salivary glands. Mucoceles are usually located in the lower lip (60 to 70% of cases), and the floor of the mouth is only involved in 6 to 15% of cases. Submandibular gland mucocele is extremely rare but should be considered in the differential diagnosis of swelling at the submandibular triangle in young children. We present the rare case of a 16-month-old child who was diagnosed with bilateral submandibular gland mucocele, presenting as serial swellings in both submandibular regions. We removed the cystic mass with the submandibular and sublingual glands to prevent recurrence.

Hemangioma is a common tumor characterized by the proliferation of blood vessels. Some authorities believe that this lesion is not a true neoplasm, but rather a developmental anomaly or harmatoma. This lesion may be present at any age, but most cases are present at birth or arise at an early age, and the central hemangioma of the jaw is uncommon. The usual radiographic appearance of a hemangioma may have one or more of the following characteristics: a soap-bubble or honey-comb effect with multiloculated cyst like lesions having a fine fibrillar framework visible within them. The roots of teeth mayor may not show resorption. The authors have experienced a case of hemangioma, that occured in anterior mouth floor and Mn.symphysis area cured by means of surgical excision without dysfunction and facial disfigurement.

This paper reports a patient who had an airway obstruction caused by a hemorrhage of the mouth floor that occurred after she underwent flapless implantation in the region of the mandibular anterior teeth. The hemorrhage may have been caused by iatrogenic malpositioned fixture and patient's hypertension. The lingual periosteum was not dissected during the flapless procedure. Therefore, when hemorrhage occurred, the blood did not drain easily into the oral cavity but instead drained into the deep neck region, which might have been the cause of the airway obstruction.

A pleomorphic adenomas (so-called mixed tumors) predominantly localize in the salivary glands. of the mixed tumors affecting the major sailvary glands. 90% ocur in the parotid gland, about 9% occur in the submaxillary gland, and 1% occur in the sublingual gland. The sites of origin of tumors of the inor salivary glands, in order of frequency, are the palate, lip, tongue, cheek, anf floor of the mouth. In the case of reported here a tremendous large pleomorphic adenima (weighting 580gm, measuring 18X7cm) occuerd in the submaxilly gland which had been growing for about 20 years.

Odontogenic maxillofacial space abscess in childeren was treated by the surgcal intervention combined with antiboitic therapy. Followings are the results after monitoring its progression. 1. Maxillofascial space abscess is mainly from the odontogenic infection and it may result in the severe states with the various fascial spaces and their relatives. So their early detection and treatment are needed. 2. The most common symptom in patients was the pain under palpation with painful swelling and the mouth floor elevation was observed in the sublingual space abscess. 3. In most cases, for its treatment, symptomatic therapy, antibiotic therapy, surgical incision and drainage were executed. If the infected tooth is possibly conserved, endodontic treatment is preferred, otherwise, it will be extracted as soon as possible.

To evaluate criteria, indications, and prognosis of the various reconstructive methods on the patients with intraoral soft tissue defect who had been treated at Dept. of Oral and Maxillofacial Surgery, Pusan National University Hospital from 2003 to 2005, we have reviewed the clinical data of the patients and analysed. The results were as follows: 1. Tongue flaps have been mainly applied on anterior portion of palate and maxilla. The survival rate was high percent, but the cooperation of patient was inevitable for the success. 2. Palatal mucosa rotational flaps were available on relative large defect on palate, oroantral fistula site. The side effect was a scaring band from secondary healing on denuded donor palate site. Sometimes the band came to be a hinderance to swallowing, phonation. 3. Forearm free flap was a workhorse flap for everywhere in intraoral defects. We had used the flap on cheek, floor of mouth, tongue without any significant complications. But the application of the flap was required for long operation time, which was disadvantageous to the old, weak patients. 4. Cervical platysmal flap could be easily applicable for buccal cheek, floor of mouth after excision of the cancer lesion. The design of the flap could be made simultaneously on neck dissection, but the danger of cancer remnants on the flap always might be remained. 5. Buccal fat pad pedicled flap must have been a primary flap for repair of oroantral fistula especially on posterior maxilla. The flap survival will be expected if the considerations for above reconstructive methods on site, size, condition of defects primarily could be made.

타석증은 대, 소타액선의 도관내에 석회화 물질이 형성되는 것이다. 타액의 점도가 높고 도관이 길고 구부러진 악하선에서 가장 호발한다. 어떤 나이에서도 발생할 수 있지만, 중년에서 호발하며 어린이에서는 드물다. 타석증의 임상 증상은 다양하지만, 부종이 가장 흔하며, 그 다음이 동통이다. 임상 검사와 방사선 검사(파노라믹 방사선 사진, 하악 교합면 방사선 사진, 타액선 조영술, 구강 내 및 구강 외 초음파, CT, MRI, 타액선 내시경)가 타석증의 진단 및 타석의 위치를 확인하는 데 도움을 준다. 치료는 도관의 절개에 의한 타석의 제거나 타액선의 절개를 포함하는 수술적 치료가 많다. 그러나, 일부는 쇄석술과 $CO_2$ 레이저, 내시경 등의 비침습적인 기술을 사용할 수 있다. 5세 여환이 구강저의 노란색 물질을 주소로 개인 병원에서 의뢰되었다. 4개월 전 처음 발견했을 때보다 3배 더 커졌으며 때때로 동통이 있었다고 하였다. 임상 검사 상, 노란색의 단단한 물질이 악하선 도관의 입구에서 관찰되었다. 와튼스 도관의 전방부에 발생한 악하선 타석증으로 진단내렸다. 국소마취하에 타석을 적출하였다.

하마종은 구강저에 발생하는 점액 낭종으로 타액선 분비도관의 파열로 인하여 점액이 연조직 내에 저류되어 생기는 가성낭종이다. 구강저의 설소대를 중심으로 편측으로 발생하며 무통성이고, 병소의 크기가 증가함에 따라 피막이 얇아져서 청색의 투명한 종창이 되는 것이 특징이다. 병소의 크기가 큰 경우에는 연하 및 발음, 저작시 문제를 야기할 수 있지만 외부로 종창이 생기거나 감염되는 것은 드물다. 하마종의 치료법으로는 자발적으로 치유되는 것을 관찰하는 방법, 단순 절개 배농, 조대술, 절제술 등이 있다. 치료법 중 하나인 조대술은 낭벽의 일부분을 제거하여 구강 점막과 연결시켜주는 술식으로 보존적이며 소아에서 추천되는 방법으로 구강내 조직의 외형을 원형대로 유지할 수 있고, 해부학적 구조물을 손상시킬 위험성이 적은 장점을 가진다. 치료 후에 자주 재발될 수 있으며, 술 후 4개월 이내에 일어난다. 이 증례는 하마종을 주소로 내원한 8세 여아에서 조대술을 시행하고 관찰하였으며 재발소견 없이 정상적인 소견을 보인바 보고하는 바이다.

Oral Lichen Planus(OLP) is a idiopathic chronic inflammatory disease with more difficult to clear and higher recurrent rate than cutaneous lesions. But, there has been no estabilished theories about the proper treatment for OLP. The purpose of this study is to examine the clinical feature, relationship with systemic disease and dental treatment of OLP patients of Korea and to gain helpful information about clinical characteristics and treatment of OLP. The subjects chosen for the study were 54 patients who had visited Department of Oral Diagnosis & Oral Medicine at Yonsei University Dental Hospital Dental Hospital and diagnosed as OLP. Previous clinical records has been reviewed and questionnaires, oral examination, laboratory examination were done and recorded. The following results were obtained : 1. Of the 54 patients, 21 were men and 33 were women with an average age of 47.8 years. 2. The most common intraoral site was bilateral buccal mucosa, followed by unilateral buccal mucosa, gingiva, vesibule, lip mucosa, glossal mucosa, palatal mucosa and mouth floor. 3. The mixed, erosive and reticular form of OLP was most frequent(83.3%) clinical form. 4. OLP patients with liver disease were 5, and drug medication patients were 7. But, we could not find its evidence of association with OLP. 5. Associated events on onset of symptom were stress, denture wearing, dental treatemtn, and common cold. 6. Associated symptoms were dry mouth, tingling, sore throat, and altered taste perception. 30.8% of patients had no specific associated symptoms. 7. Aggravating factors of symptom were peppery food, hot food, fatigue, toothpaste, salty food, sour food, tension, and conversation. Reducing factors were cold food, sleeping. 69.2% of patients had no specific reducing factors. 8. There were no significant differences between normal papulation and OLP patients in CBC, SGOT< SGPT, Serum iron, Total iron binding capacity. 66.7% of subjects were positive response to fungus study for Candida Albicans. The incidence of stress and dental treatment on onset of symptom appeared high in OLP patients. Especially, high incidence of positive response to fungus study for Candida albicans, prescription of anti-fungal agents and dental treatment considerations may be helpful to treatment of OLP.
