The treatment of cleft lip and palate must be based on a complete knowledge of the anatomy, physiology and growth of the involved deformity, because of not only the appearance but also impaired functions such as phonation, mastication, respiration and lingual posture of the maxillomandibular complex. Delaire has long studied all these aspects, and has published many numbers of articles and constructed a philosophy concerning the significance and interrelationship of the various structures. The results obtained from its application seem to be particularly valid from a clinical point of view, although it has not all been scientifically supported by experimental data. For these reasons, Delaire's primary unilateral and bilateral cheilorhinoplasty procedures are particulary good, as is his secondary gingivoalveoloplsty procedure during the course of the surgical repair of the hard palate. In order to understand Delaire's philosophy, it is necessary to consider the normal and pathologic anatomy of the structures involved in the deformity, the role of some structures, such as nasal septum, musculature, and tongue, and some functions, such as dental occlusion or nasal respiration, which play important roles in maxillary and particularly premaxillary growth. Despite of important concept and meanings, Delaire's philosophy has not been introduced widely to our Korean cleft surgeons yet. So authors will summarize the basic concepts of Delaire's philosophy according to already published literatures and lectures based on our previous treatment outcomes.

The purpose of this study is to introduce the method of palate repair that combines minimal hard palate dissection and radical retropositiong of levator musculature, which was presented by Sommerlad. As this method presents, additional use of the operating microscope enables atraumatic and radical dissection, and it might provide more improved speech function to the patients. A total of 17 patients with cleft palate underwent Sommerlad's method from December 2003 to August 2004. The mean follow-up period was 4.5 months. The use of a microscope provided high quality variable magnification and good illumination at the operating field. Repair was carried out through incisions at the margins of cleft with mucoperiosteal flap elevation. Muscles were rearranged and repaired properly. It was unable to evaluate the improvement of speech because the patients were too young to learn meaningful speech. Average operating time including anesthetic induction time, V-tube insertion and recovery from anesthesia was 2 hours 45 minutes which was not quite different from conventional method's operating time. Oronasal fistula developed in 2 patients of them. One of them was healed spontaneously. As meticulous and radical muscle dissection was possible with Sommerlad's method, we could minimize the trauma to the muscular and neurovascluar structure. In addition, we expect better faculty of speech as a result of this method although longer follow-up time was unavailable.

The author observed the distribution of mast cells in the hard palate wound healing of healthy male albino rats weighing about 100gm. The mild wounds were made antero-posterior linealy by sugical knife. The results were as follow : 1. At the from three days to five days after wound, the number of mast cells were markedly increased. 2. In the wound healing process, mast cells were more distributed in the lamina propria than in the submucosa.

Pleomorphic adenoma(benign mixed tumor) is the most common tumor of the major salivary glands, constituting approximately 70 per cent of benign tumors of these glands. The term mixed tumor was introduced in the nineteenth century to stress the dual origin of this neoplasm from epithelial and mesenchymal elements, and the designation pleomorphic adenoma is preferred because it emphasizes both the epithelial origin and the variety of histological patterns found in this common salivary gland lesion. Rauch, in a review of 4245 pleomorphic adenomas, found 92.5 per cent in the major salivary glands and 6.5 per cent in the minor salivary glands, 8 per cent arose in the submandibular glands, and in another large series of over 6,000 cases, approximately 4 per cent arose in the hard and soft palates with equal frequency in each. The prognosis of pleomorphic adenoma depends more upon the choice and adequacy of treatment than upon histological appearances. The accepted treatment for this tumor is excision. With adequate surgery recurrence rates of less than 1 per cent can be obtained. In this hospital, I experienced two patients who were identified PMA which occurred in the hard palate and submandibular gland. The lesions were successfully treated by surgery.

The purpose of this study was to investigate the functional adaptation of the tongue, the hyoid bone, the digastric muscle and the upper airway and the variables predicting postoperative stability following orthognathic surgery in patients with mandibular prognathism. 18 patients were selected(8 men and 10 women) for this study, who had received orthognathic surgery. Their lateral cephalograms, those were taken preoperatively, immediate postoperatively and over 6 months follow-up, were traced and analysed. The results were as follows : 1. The downward displacement of the hyoid bone and extended head posture were recognized, right after operation. Statistically significant correlations were found between the changes of the mandibular position and the digastric muscle and the change of head posture during operation. 2. The tongue was displaced downward following the hyoid displacement postoperatively. Statistically significant correlations were found between the change of the mandibular position and the change of the distance of the tongue and hard palate, and between the change of head posture and the changes of the upper airway sizes, the digastric muscle and the hyoid position during over 6 month's follow-up. 3. The change of the distance of the tongue and hard palate was the most significant factor for prognosis during over 6 month's follow-up. 4. There were no variables before operation to predict the postoperative stability and the constriction of the upper airway.

본과에서는 신장 이식자에서 매우 드물게 발현되는 구강내의 카포시 육종을 경험하였으며 이와 같이 장기 이식 후 면역 억제제를 투여하는 환자에서 구강내 카포시 육종의 발현시에는 전신적으로 이환된 경우가 많으므로 특별한 주의를 요하리라 사료된다.

본 교실에서는, 경구개에 발생한 과립세포종을 경험하여 문헌 고찰과 함께 면역조직화학적 특성을 확인 하여 기술 하였다. 본 종양세포는 S-100, CD68, NSE 등에 양성 반응을 보여, 과립세포종의 기원이 neural origin, 특히 Schwann's cell이라는 최근의 여러 연구들의 결론에 병행함을 보였다. 증례가 많지 않은 본 종양에 대한 향후 더 많은 증례와 연구가 필요하리라 사료된다.

Squamous cell papillomas are one of the most common lesions of the oral mucosa with a mucosa of the hard and soft palate, including the uvula, palate, tongue and lips. As an oral lesion, it raises concerns because of its clinical appearance, which may mimic exophytic carcinoma. Its pathogenesis is related to the human papilloma virus (HPV), but there is controversy regarding its viral origin. Many considered its pathogenesis as being from the HPV. But recent literature suggests that the presence of HPV may be merely an incidental finding unrelated to the development of a squamous papilloma. We accidentally found a patient not related to the HPV of oral squamous papilloma on the tongue, and we will report this case with literature review.

Mucinous cystadenoma, one of the subtypes of cystadenomas, is a rare benign salivary gland tumor. Most of the cases reported tumors presenting as asymptomatic, slow growing, single masses, primarily occurring in the parotid glands, buccal mucosa, and hard palate. This report describes a case of multiple mucinous cystadenomas that presented as subcutaneous swellings in both cheeks, which were mistaken for a benign subcutaneous tumor. A complete surgical excision was performed through an intraoral incision. There were no recurrences or complications. A diagnosis of mucinous cystadenoma was made by histopathological examination. Mucinous cystadenomas are differentiated from other salivary gland tumors based on the pathological findings. A malignant transformation is also possible. Preoperative imaging cannot identify mucinous cystadenomas because of their small size and atypical features, and needle biopsy has its limitations in such salivary gland tumors. Therefore, accurate diagnosis and treatment through surgical excision become important.

본 증례에서는 치근 절제술의 합병증으로 오인할 수 있는 재발성 구내 헤르페스에 대해 보고하고자 한다. 49세 남환이 상악 좌측 제1대구치의 근심협측 치근의 수직파절로 근관치료 후 근심협측 치근절제술을 시행하였다. 19개월 후 환자는 뜨거운 고기를 씹은 후에 좌측 구개부가 헐고 불편하다는 주소로 재내원하였다. 구강 내 검사 시 상악 좌측 제1대구치의 구개측 치은에 농루로 의심되는 융기부위가 관찰되었다. 임상 검사에서 치아는 치주탐침 시 출혈을 보였고 5 mm 이하의 치주낭이 관찰되었으나 치아동요도는 없었다. 방사선 검사에서 구개측 치근에 치주인대강 비후의 소견을 보였다. 농루로 의심되는 부위에 gutta percha cone을 이용한 농루 추적을 시도하였으나 삽입되지 않았다. 시야를 넓혀 구개 전방부를 관찰하였을 때 작은 원형의 궤양이 다수 관찰되었고 환자는 동통을 호소하였다. 이상의 소견으로 비치성 동통으로 판단하여 구강내과에 의뢰하였고 구강내과에서 재발성 구내 헤르페스로 진단하여 항바이러스제 처방 후 환자의 통증 및 구개측 치은의 궤양이 소실되었다.
