The purposes of this study were to evaluate the nasolabial angle changes between closed lip position at centric occlusion and relaxed lip position at which the bite is open so that the lips do not touch and to elucidate the significance of the relaxed lip position for dentofacial diagnosis. Methods: The subjects consisted of 60 (35 Males, 25 Females) skeletal Class III malocclusion adult patients (mean age 23.3 years) with anterior crossbite. Results: In Class III malocclusion adult patients, there were significant differences in the nasolabial angle changes between closed lip position and relaxed lip position. Using the cluster analysis, the subjects were divided into three groups according to the pattern of nasolabial angle change: Group 1 (N = 27, 45%, $-8\;{\sim}\;1$), Group 2 (N = 30, 50%, $2^{\circ}\;{\sim}\;17$), and Group 3 (N = 3, 5%, over 18). Conclusion: The results showed that the pattern of the nasolabial angle change between closed lip position and relaxed lip position varies in skeletal Class III malocclusion patients. Thus, relaxed lip position should be taken into account when diagnostic records are obtained and analyzed to accurately to evaluate the facial soft tissues and predict facial esthetics after surgical-orthodontic treatment.

This paper studied the usefulness of 'Line marks of the proper nouns of Korean origin in the Hikun of the Shakunihongi' as a material to analyze tone marks of the proper nouns of Korean origin. First, the analysis showed that Line marks of Shakunihongi do not reflect the Middle Chinese sounds directly. Second, the analysis revealed that Jyosyo and Kyosyo tend to be marked to a mark. Next, in order to analyze the interference of the Japanese sounds, the tone of Japanese Kan-on and Go-on and the correspondence were studied. The result showed that Kyosyo of Japanese Go-on is marked to a point. This means that the tone of proper nouns of Korean origin in Shakunihongi were not influenced unilaterally by Japanese Kan-on and Go-on. Also, the line marks tended to be seen in Bokun monotone kanji. The line marks were found to be consciously distinguished from the Circle marks. There is a characteristic that Line marks of proper nouns of Korean origin in Shakunihongi are marked to Hyoso. This is the same tendency with Circle marks. That is why Line marks in Shakunihongi can also be used as a tone-mark material of proper nouns of Korean origin.

Nasolabial cyst is a rare non-odonotogenic, soft-tissue, developmental cyst arising inferior to the nasoalar region of the face. The most common clinical finding of the nasolabial cyst is that of a slowly enlarging asymptomatic swelling typically without radiographic abnormalities. This case report describes a 25-year-old man in which the clinicopathologic findings and an erosive finding on the computed tomographic scan on maxilla were consistent with nasolabial cyst. The histopathologic features, differential diagnosis, treatment and prognosis are discussed.

The nasolabial flap is a well-known one for regional repairs. When the inferior-based nasolabial flap was used, the beard area was avoided, and subcutaneous flap pedicle versatility was increased. The inferiorly-based nasolabial flap with a subcutaneous pedicle was useful in the primary repair of surgical defects of the floor of mouth. maxillary alveolus, palate. and tonsillar area in selected patients.

In order to evaluate the changes before and after secondary operations in the patients with cleft lip objectively using full face photographs, the author analyzed results of improvement on nasal width and mouth width and asymmetry of nostril. 1. The ration of asymmetry of thenostril is changed from average 1.24 preoperatively to average 1.08 postoperaively : 61.2% is improved postoperatively. 2. The ratio of nasal width compared with intermedial canthal distance is changed from average 1.15 preoperatively to average 1.10 postoperatively : 3.8% is reduced posteroperatively. 3. The ratio of mouth width compared with intermedial canthal distance is changed from average 1.08 preoperatively to average 1.03 postoperathvely : 4.1% is reduced posteroperatively.

Our Goal of modified segmental osteotomy on maxilla accompanied by mandibular anterior subapical osteotomy was to get the best results from patients of bi-alveolar or bi-maxillary protrusion. In this study, cephalometric and photo (en face, profile) analysis have been compared to define the soft tissue change after surgery. Lip protrusion was efficiently reduced and nasolabial angle was much obtused. Although nose was a little widened, it was quite acceptable. Blood circulation on osteotomized segment was well maintained. This relatively simple methods could be successfully applied to many patients.

The purpose of this study was to compare four groups of Oriental young adults (169 males and 174 females) with normal occlusion and well balanced faced. Lateral cephalograms of 100 Koreans, 100 Chinese, 72 Vietnamese and 71 Japanese were digitized and six profile measures were computed. Analyses of variance showed that total facial profile(Gl'-Pr'-Pg') of Chinese was significantly less convex than the profile of Koreans or Vietnamese. Facial profile(Gl'-Pr'-Pg') of Chinese was also significantly less convex than that of Vietnamese. Holdaway's soft tissue angle(Pg'-LS:N-B) was significantly greater in Vietnamese than Chinese and Koreans, who were in turn greater than Japanese. The upper lip of Vietnamese is significantly closer to Ricketts' esthetic plane, than Chinese; Koreans and Japanese are significantly further behind the plane than Chinese. The lower lip of Koreans and Japanese was close to the esthetic plane, while Chinese and Vietnamese were approximately 2mm ahead. The nasolabial angle was significantly smaller for Chinese and Japanese than Koreans and Vietnamese. Sex differences were primarily dependent on the nose; total facial convexity and the nasolabial angle wert significantly larger in females than males. The results of this study demonstrate that a single standard of facial Profile is not sufficient or appropriate for Oriental patients.
