악안면외과 교정술은 악골, 안면 혹은 구강에 어떤 기형증에 있을때 이를 외과적 처치에 의하여 개선하거나 치료하는 것을 말한다. 악안면, 구강영역에 발생하는 기형증은 여러가지가 있으나 대체로 비대칭성안모, 악골의 전돌증이나 후퇴증, 개교증, 토순, 구강파열 및 선천성안모발육부전증등 여러 가지가 있다. 본인은 지난 83년 2월부터 5월 초순까지 스위스 쥬리히 치대 악안면외과 교실을 방문하여 이곳 교수들과 접하고 의견을 나누었으며, 강연도 듣고, 하여 주기도 하였다. 또한 이곳 병원에서 외과적안모교정술 등 여러 가지 새로운 시술방법등을 견학하면서 새로운 시술방법을 연구한 바 있다. 지면과 시간이 허락되는 범위안에서 앞으로 수회에 나누어서 악안면외과 교정술에 대하여 구체적으로 소개하고저 한다.

Differential diagnosis of the malignant lesion and the benign lesion is critically important for the precise treatment. A clinician should diagnose in a comprehensive manner considering clinical, radiological, and histopathological perspectives. The lesion in the oral cavity in this study was clinically and radiologically malignant. However, the lesion was histopathologically benign. Surgical intervention was not performed except biopsy. The lesion improved after about one month of supportive medication after the biopsy. The importance of decision making process was emphasized in this report.

There are some methods of approach to the temporomandibular joint. The preauricular, the endaural and the postauricular incision are frequently used among those. The preauricular incision necessiates a preauricular scar, possible postopertive facial nerve damage and is the least cosmetically desirable incision. The endaural incision is more esthetic than preauricular incision, but it is not sufficient. The postauricular approach allows adequate exposure with decreased occurence of injury to facial nerve and excellent cosmetic results. The purpose of this report is to discuss the surgical approach of postauricular incision to the cases of TMJ ankyloses, internal derangement and condylar fracture of mandible.

Undifferentiated pleomorphic sarcoma (UPS) in the mandible region is a rare malignant neoplasm. We encountered the case of a patient who had been diagnosed with deep benign fibrous histiocytoma (DBFH) prior to surgery, but the final biopsy revealed the presence of tumor tissues in the resected margin, which indicated a UPS. Therefore, radiotherapy was conducted post-operatively, but the tumor recurred approximately 3 years later and a second surgery was performed. The difference between the initial and final diagnoses was considered to be due to the characteristics of the tumor, as it involved both benign and malignant components. DBFH and UPS can occur in young women. DBFH can transform to a malignancy and UPS may also appear as a benign tumor during early biopsy. Hence, attention should be paid to diagnosis and treatment methods, and ongoing close observation is required.

Cervicofacial subcutaneous emphysema is defined as the abnormal introduction of air into the subcutaneous tissues of the head and neck. It is mainly iatrogenic and traumatic in origin. Our two case reports are also due to the same cause, but the features of the trauma and the site of the dental treatment are different from the existing reports. A 29-year-old man visited our hospital with facial swelling and pain after experiencing facial trauma in a soccer game. Another 55-year-old woman visited with similar symptoms after replacement of her maxillary anterior fixed prosthesis. In the two cases presented, subcutaneous emphysema was gradually treated with no complications during antibiotic prophylaxis and supportive care. In this paper, we report two cases of traumatic and iatrogenic subcutaneous emphysema and their diagnoses, etiologies, complications, and treatments based on a literature review.

This research aimed to discuss the necessity of education and evil through perspective of Sunja and Hannah Arendt. In case of Sunja, it was reviewed by his opinion about Sunja as the central figure. As for Arendt, it was researched with "Eichmann in Jerusalem" as the central figure which she wrote participating in the trial process of Eichmann who was a war criminal of Nazi. Sunja thought evil as the nature of people and understood that they all are originally selfish, envious, and seeking desire. Therefore, Sunja thought it is important to properly seek human desire. He claimed Haw Seong Gi Wi(化性起僞, changing evil human nature into goodness through manner) which changes human nature from evil to goodness. A teacher who leads evil into goodness is surely needed in the process of Haw Seong Gi Wi. At the same time, in the dimension of educational content it put stress on the role of Ye(禮, manner) which lets them realize discernment so that they properly seek human desire and Ak(樂, harmony) which harmoniously controls human emotion, and key point on education regarding Ye and Ak. As for Arendt, however, she recognized evil as normal one. Even though he thought that conforming the order of superior authority was the best value and then took evil of killing many Jews in thoughtlessness, Eichmann maintained that he did not take evil but only conformed the order. This way, people could take evil in thoughtlessness in totalitarianism, and it makes circumstance that they could not take goodness. Therefore they could take evil in thoughtlessness and experience the radical evil and the banality of evil. Accordingly, political praxis which guarantees people's plurality as the words and praxis is needed. It is named natality because the truth that they are born in this world is a starting point, and makes the essence of education. In this process, teachers have to be a representative of this generation for children as new social members, and be able to keep children's newness. Sunja and Arendt have the same equality and difference in that they referred to the necessity of education to overcome human evil. It is the same quality that goodness could recover the function of community and the practice of education is considered important in the goal of education and the dimension of directivity. It is different in methodical characteristic of education that Arendt, however, suggests praxis as the way that they express themselves in totalitarianism while Sunja thought that continuous practice piling up virtue for goodness is important.

The purpose of this research was to establish the culture condition for dissociated submandibu -lar gland (SG) cells. After trypsin digestion of SG from 3-4 weeks old mice, dissociated cells were cultured in 1OO/o fetal bovine serum-Dulbecco's modified Eagle's medium (FBS-DME) or 0.5-2% low protein serum replacement-DME (LPSR-DME) on plastic surface to form monolayer. The effects of FBS, LPSR and hormones on the growth and function of cultured SG cells were examined. SG cells dissociated by enzyme were successfully cultured and were characterized as epithelial-like cells by light and electron microscope. The maximal DNA synthesis of cultured SG cells was achieved by DME containing 5-10% FBS. The same results were obtained when the effects of LPSR on cell proliferation were examined up to a LPSR concentration of 2%. SG cells cultured in 20/o LPSR-DME expressed a population doubling time of 42.5 hrs and a saturation density of 1.2 $\times$10 5cell/cm$^2$. Dihydrotestosterone (DHT) in medium did not influence on the DNA synthesis of the cultured SG cells, but stimulated protein synthesis of the SG cells. Thyroxine (T4) stimulated protein synthesis of the SCI cells markedly in a dose-dependent fashion. EGF secretion by the cultured SG cells increased significandy by DHT and or T4 trearment. This finding indicated that secretion of EGF by the SG cells was under the control of the hormones such as androgen and thyroid hormones. It seems to be that the culture condition described here can be used as a useful tool for further research on the SCI cells.

In cases of extensive prosthetic restoration, correction of occlusal contact is often needed, as it is the essential component for a successful restoration. If occlusal contact is given incorrectly, various symptoms of occlusal trauma can occur of which temporomandibular joint disorder (TMD) is one of them. As one of the common symptoms of TMD, patients may suffer with masticatory muscle disorder and temporomandibular joint pain. This case presents satisfactory results for the improvement of masticatory muscles and temporomandibular joint pain of a TMD patient, caused by incorrect occlusal contact of the restoration, by replacing the prosthesis after occlusion correction.
