Many authors reported the etiology of hypoplasia of the nasomaxillary complex as trauma, infection, underdevelopment. To correct these deformities, Le Fort II Osteotomy and its modification has been popularly applied. This method enabled total advancement of nasomaxillary complexes and acquirememt of midfacial esthetics. But it has some limitations such as various occlusal deviation or lateral shifting of nasomaxillary complex in case of nasomaxillary retrusion. We grouped these patients as follows : 1. Nasomaxillary retrusion without shifting of nasomaxillary complex (1) Anteroposterior deviation of occlusal plane (2) Lateral deviation of occlusal plane(including canting) (3) Supero-inferior deviation of occlusal plane (4) Combined disturbance of occlusal plane without shifting of nasamaxillary complex 2. Lateral shifting of nasomaxillary complex with or without deviation of occlusal plane We performed Le Fort II and I combined osteotomy on eleven cases of midfacial deformity from June 1994 to July 1997 and in most of the cases, followed up maximum 36 months and could acquire positional stability and improvement of facial eathetics.

OBJECTIVES: This paper presents the information on the incidence of cancer from the population-based cancer resistry in Kangwha County. Material and METHODS: This investigation is based on Kangwha cancer registry. The data included cases of cancer diagnosed from 1986 through 1992. The diagnosis of cancer was confirmed by a team of physicians and nurses with the medical records kept in the clinics and hospitals based on the diagnostic criteria recommended by WHO. Home visitings were also made to cancer patients confirmed in every 6 months for the follow up and for the collection of relevant information directly from the patients. RESULTS: A total of 992 cancer cases were registered during 1986 - 1992. The age-adjusted cancer incidence rate of all site is 201.7 in men and 110.7 in women. The most common cancer is the stomach cancer in both sexes. The age-adjusted incidence rate of the stomach cancer is 65.9 in men and 25.0 in women per 100,000 population. The lung cancer(33.8) and liver cancer(27.7) are next common cancers in men. The cervical cancer(21.8) and lung cancer(8.4) are next in women. CONCLUSION: The most common cancer is the stomach cancer in both sexes. The annual age-adjusted incidence rate of the stomach cancer is 65.9 in men and 25.0 in women per 100,000 population.

This study was undertaken to investigate the relation between orthodontic force magnitude and the amount of tooth movement. And more light force application for reducing root resorption. Twenty-four rats were divided into three experimental groups(A, B, C) based on force magnitude and application method. Springs of 50g force were applied to A group, spring of 100g force were applied to B group and springs of 25g force were applied to C group initially, and after 4 days springs of C group were changed to springs of 50g force. Two kinds of sentalloy(R) (GAC U.S.A) closed coil spring, 50g and 100g, were used. And we made 25g springs by heat treatment process of 50g spring. Each spring was inserted between the maxillary central incisor and the maxillary left first molar. Amounts of tooth movement were measured everyday by digital caliper(Digimatic(R) , Mitutoyo, Japan) under inhalation anesthesia for 15 days, all rats were sacrificed and histological sample were obtained with Hematoxyline-Eosin stan and Masson's trichrome stain. Following conclusion were made : 1. Group B showed the mean cumulative tooth movement of 2.19+/-0.41mm at 15th day, which was greatest among three groups, followed by group C(2.06+/-0101mm), group A(1.90+/-0.49mm) respectively. However, there was no statistically difference among three groups. 2. All groups showed general tooth movement pattern and A, B, C group finished lag phase at 9th, 8th, 7th day, but three was no statistical significance. 3. Group A, B, C showed root resorption and especially group B showed the most severe root resorption and group C showed milder root resorpting than other groups. According to the above results, large initial force with the development of a fairly widespread hyalinized zone may cause severe root resorption, so initial force should be applied lightly to reduce hyalinized area and eventually root resorption and then increased force will induce efficient tooth movement.

The microform cleft lip is the mildest expression of cleft lip and nose deformity, but it has no specific definition, classification, and few methods have been reported for its correction. It is characterized by deformity of the nostril, skin striae of the upper lip, notching of peaked Cupid's bow, deformity of the vermilion, and anomaly of the upper lateral incisior and alveolar ridge on the affected region. Sixty-three microform cleft lip patients were operated on between Dec. 1993 and Sep. 1998 in our department(29 males and 34 females). The age of the patients ranged from 5 months to 30 years(Mean 9 years). We classified and treated the microform cleft lip as follows: Class I: Cleft lip nose with very slight lip deformity Class II: Minimal lip deformity without vermilion notching Class III: Mild lip deformity with slight vermilion notching. The goals in the correction of a microform cleft lip are to obtain an esthetically pleasing upper lip and nose, and to reestablish muscle continuity for improved function. To attain these goals, we used the above classification and satisfactory results were obtained by treating the microform cleft according to the classification.

We report a case of dilated pare of Winer occuring in a 33-year-oid female patient. Dilated pore belongs to adenoma or organoid group of benign hair differentiation tumors. The patient has had a giant comedone on the right submandibular area for 1 month. Histopathologic features revealed rnarkedly dilated pilar infundibulum lined by epidermis that is atrophic near the ostium but hypertrophic deeper in the cystic cavity. Three months after excisional biopsy, there was no recurrence.

BACKGROUND: In anemic patients, it has been usually traditional practice to correct the anemic state with preoperative blood transfusion. But now, there is an increasing tendency of refusing blood transfusion due to the transfusional complications, especially AIDS etc. The purpose of this study is to survey the effects of anesthesia in anemic patients with normal cardiopulmonary function compared to non-anemics. METHOD: 40 patients with uterine myoma were divided into two groups, an experimental group of 20 patients with hemoglobin concentration of 8~10 gm% and a control group of 20 patients with hemoglobin concentration higher than 10 gm%, and their blood pressure, pulse rate and arterial oxygen saturation were monitored and compared. RESULTS: There were no significant differences between two groups in blood pressure, pulse rate and arterial oxygen saturation. CONCLUSION: Preoperative blood transfusion, in patients with moderate anemia, does not seem to be a mandatory practice.
