Cupid's bow, upper lip, columella, and ala of nose are esthetically important, in which their symmetrical plasties determine success or failure of the surgery in cleft lip and palate patients. Z-palsty and its modifications are simple and effective. The double Z-plasty is economical in surgical time and esthetics in reconstructing the cupid's bow compared with other methods. We report a 29-year-old male patient who represented reversed cupid's bow and whistle deformity after the primary repair of the cleft lip. He was corrected the cupid's bow using a double Z-plasty. The reversed cupid's bow was corrected to a normal shape and the whistle deformity disappeared. The tightness of the upper lip was relieved after the operation. The double Z-plasty was esthetically successful because the procedure was limited in the vermilion and did not produce a new scar on the skin. Furthermore, the lip tubercle became protuberant. The cupid's bow was symmetrically smoothly curved at 4 years after the operation. These results indicate that the double Z-plasty is simple, less traumatic to the surrounding tissues, and suitable for the correction of whistle deformity.

Objective: The aim of this study was to evaluate the facial dimensions of young adult women with a preferred facial appearance and compare the results with those from the general population. Methods: Twenty-five linear, nine angular, and three area measurements were made and four ratios were calculated using a sample of standardized frontal and lateral photographs of 46 young adult women with a preferred facial appearance (Miss Korea group) and 44 young adult women from the general population (control group). Differences between the two groups were analyzed using multivariate analysis of variance (MANOVA). Results: Compared with the control group, the Miss Korea group exhibited a significantly greater facial height, total facial height (TFH; trichion-menton), facial width (tragus right-tragus left), facial depth (tragus-true vertical line), and trichion-nasion/TFH ratio and smaller subnasale-menton/TFH and facial width/TFH ratios. Furthermore, the control group had smaller intercanthal and interpupillary widths. Conclusions: The Miss Korea group exhibited longer, wider, and deeper faces compared with those from the general population. Furthermore, the Miss Korea group had larger eyes, longer but less protruded noses, longer and more retruded lower lips and chins, larger lip vermilion areas, and smaller labiomental angles. These results suggest that the latest trends in facial esthetics should be considered during diagnosis and treatment planning for young women with dentofacial abnormalities.

The painted folding screen of Crown Prince Munhyo at Boyangcheong, Munhyo-seja Boyangcheonggyebyung, was made to record the court ceremony where Crown Prince Munhyo(1782-1786), the firstborn son of King Jeongjo, met his first teacher called Boyanggwan for the first time at Boyangcheong, a government agency specifically founded to provide education for a crown prince, in January 1784. Having never been treated before, this 8-fold screen is still in its original presentation of Joseon Dynasty screen paintings of court ceremonies in the 18th century. The mountings of folding screens in Joseon Dynasty has been researched through the study of the mounting of the Boyangcheong screen and the conservation treatment of the screen has been based on this research. The result of the pigment analysis shows the use of lead white, red lead, vermilion(cinnabar), azurite, malachite, litharge(massicot), carbon black(Chinese ink). The microscopic observation has proved that the painting was painted on verso in most areas and finished on recto to highlight the details or to produce subtle hues by applying light colors.

The elements of the pigments used on the wall painting in Ssangyeongchong (Tomb of Two Pillars) from Goguryeo in the Nampo area of Pyeongyang were analyzed to confirm their mineral compositions and features of the painting. Specifically, the non-destructive X-ray fluorescence spectrometer (XRF) was used. On the other hand, the mineral composition of the background and pigment layers were analyzed using an X-ray diffractometer (XRD). The results of these analyses suggested that the lips of the characters in the painting were painted with HgS, and their faces, painted with HgS(Cinnabar/ vermilion) mixed with CaCO₃. Note that lead white pigment [2PbCO₃·Pb(OH)₂] was found only on the bottom layer of the painting, indicating that the wall painting was likely to have been created using the Secco method.

This study analyzed the pigments used in two portraits of Sim Hui-su using scanning electron microscopy/energy dispersive spectroscopy(SEM/EDS), X-ray diffraction(XRD) analysis, and microscopic observation, and then compared the results to those from nondestructive analysis. It was estimated that cinnabar/vermilion and minium were used for the red pigment, azurite for the blue pigment, atacamite for the green pigment, and lead white for the white pigment. These results were compared to the pigments of six portraits with a similar format, full-length official-attire portraits from the $17-18^{th}$ century Joseon period. It was revealed that the composition of the pigments used in the portraits varied depending on the date of production. Iron oxide, another red pigment, was used in the $18^{th}$ century. As for the blue colorant, smalt was used in the late $18^{th}$ century, whereas it was absent until the early $18^{th}$ century.

Purpose: Mulliken's method allows for normal nasal and lip growth, which in turn forms a natural shape of the philtrum. Therefore, we used a modified Mulliken's method to correct unilateral and bilateral cleft lip nasal deformities and followed the patients for 10 years. Methods: Ninety-one patients, who had undergone repair of unilateral and bilateral cleft lip and nasal deformity simultaneously using Mulliken's method during the time period from June 1997 to June 2009, were enrolled into this study. To follow-up of the growth of the lips and nose after the operation, the following 5 anthropometric measurements were analyzed: nasal tip protrusion, columellar length, upper lip height, cutaneous lip height, and vermilion mucosa height. Results: Using this method, we obtained a result that there was no significant difference in the development of the lip compared to the normal control group, and that the bilateral cleft lip patients' nasal projection and columellar length was shorter than that in normal persons. Both measures were statistically significant. Conclusion: Mulliken's method is a superb surgical technique, which enables the normal development of the nose and lip, which further allows for the innate philtrum appearance. The author's result does not seem to be meaningful, because the normal rate of nasal growth is slow before adolescence; however, we recommend additional follow-up and accordant treatment, if needed, once the nasal growth is complete.

Purpose: The objective of this retrospective study was to assess the skeletal stability after orthognathic surgery for patients with cleft lip and palate. The soft tissue changes in relation to the skeletal movement were also evaluated. Methods: Thirty one patients with cleft received orthognathic surgery by one surgeon at the Craniofacial Center, Chang Gung Memorial Hospital, Taoyuan, Taiwan. Osseous and soft tissue landmarks were localized on lateral cephalograms taken at preoperative (T0), postoperative (T1), and after completion of orthodontic treatment (T2) stages. Surgical movement (T0.T1) and relapse (T1.T2) were measured and compared. Results: Mean anteroposterior horizontal advancement of maxilla at point A was 5.5 mm, and the mean horizontal relapse was 0.5 mm (9.1%). The degree of horizontal relapse was found to be correlated to the extent of maxillary advancement. Mean vertical lengthening of maxilla at point A was 3.2 mm, and the mean vertical relapse was 0.6 mm (18.8%). All cases had maxillary clockwise rotation with a mean of 4.4 degrees. The ratio for horizontal advancement of nasal tip/anterior nasal spine was 0.54/1, and the ratio of A' point/A point was 0.68/1 and 0.69/1 for the upper vermilion/upper incisor tip. Conclusion: Satisfactory skeletal stability with an acceptable relapse rate was obtained from this study. High soft tissue to skeletal tissue ratios were obtained. Two-jaw surgery, clockwise rotation, rigid fixation, and alar cinch suture appeared to be the contributing factors for favorable results.

The outcome of primary surgery for cleft lip is judged by its effects on the quality of oro-facial function and development. Many surgical techniques have been tried to obtain better results, however, Delaire introduced a technique of functional closure of the lip and nose, based on the findings of no true hypoplasia in the tissues either side of the cleft. In a seven-month-old Asian male patient with unilateral incomplete cleft lip, we carried out the primary closure by modified Delaire's technique. With no alveolar bone graft, the vertical incision on the nasal base was omitted in this patient because of his acceptable symmetry of nose. Also, a small Z plasty was added on the non-cleft side. The V-shaped incisions, whose notch was located on each side of the red vermilion, were designed and beveled incisions were performed for the rehabilitation of lip length and thickness, considering the postoperative wound contracture. We assured that this modification of Delaire's technique could be applied for various cases of primary closure of incomplete cleft lip.

The Nectar Ritual Painting(Jeung7551) in National Museum of Korea is estimated to have been produced in the 16th century. Ezimagodo who is the head priest of Ruganji in Kyoto, Japan donated this painting in 2010. Overall, damages were serious, such as missing, staining, folding, insects of the face and mounting silk, therefore, it need to conservation treatment. The treatment of conservation in painting was removing surface stains and repairing missing area. It was mounted by following the original form. The analysis result of textile in mounting and support fiber used silk and hemp in microscope. Pigments in paint were divided into six color types. This painting was used that vermilion(cinnabar) and red lead for red color, litharge(massicot) and gold for yellow color, lead white for white color, malachite for green color, azurite for blue color, and carbon black(chinese ink) for black color.

Purpose: It is accepted universally that correction of the cleft lip nasal deformity requires multiple stages of surgery. Following primary lip repair in infancy or early childhood, secondary surgery to improve the deformity of the lip and nose is frequently necessary. A suitable surgical procedure to correct the accompanying deformity, such as cleft palate and alveolus, must be carried out at an appropriate age. In developing countries, it is common for patients with cleft lip nasal deformity to present severe secondary deformities in adolescence, because of poor follow-up and inappropriate surgery. Methods: The first patient was a 12 year old Mongolian boy. He presented prominent lip scar, short lip, wide columella, asymmetric nostril, palatal fistula, cleft alveolus, and velopharyngeal incompetence. He underwent cheilorhinoplasty, transpositional flap, alveoloplasty by iliac bone graft, and sphincter pharyngoplasty. On follow-up, a bilateral maxillary hypoplasia and a class III malocclusion developed. He underwent LeFort I osteotomy and maxillary advancement at the age of 16 years. The second patient was an 18 year old Eastern Russian girl. She presented with a deviated nose, right alar base depression, short lip, protrusion on vermilion, large palatal fistula, and severe VPI due to short palate. She underwent the combined procedure of cheilorhinoplasty, corrective rhinoplasty, tongue flap for palatal fistula, and superiorly based pharyngeal flap. And the tongue flap was detached at postoperative 3 weeks. Results: The overall results have been extremely pleasing and satisfactory to patients. There were no postoperative complications. Conclusion: We discovered the one stage operation for radical correction was sufficient procedure to provide excellent clinical outcomes in patients with severe cleft lip nose deformity.
