Cleft lip lower-lip deformity is a secondary deformity in patients who underwent primary cheiloplasty of the upper lip, characterized by an enlarged and anteriorly rotated lower lip. In these cases, soft-tissue imbalances remain even after skeletal correction with orthognathic surgery, and additional soft tissue treatment is required for lip harmony and esthetic facial balance in CLP (cleft lip palate) patients. This study describes three cases of transverse myomucosal excision of the lower lip for correction of cleft lip lower-lip deformity to restore facial esthetic balance. Each patient underwent orthognathic surgery, rhinoplasty, or upper lip revision cheiloplasty according to condition. Postoperatively, volume of the lower lip decreased and lip harmony was improved in all three patients. The surgeon should fully understand the anatomical structure around the lips and be able to evaluate overall harmony of the soft tissue. When a lower lip deformity is present, careful surgical planning and execution are important for each patient.

Purpose: The authors accessed the anthropometric measurements of fourty non-cleft normal a three-month-old infant and using this obtained data as a basic guideline, authors applied the modified Noordhoff technique for the treatment of bilateral cleft lip. Methods: Over a period of 10 years, a total of 21 bilateral cleft lips were operated. 13 cases of complete and 8 cases of incomplete bilateral cleft lip and palate. In the complete type of bilateral cleft palate, elastic head cap and passive intraoral appliance were applied at 1 to 2 week of age for 2 months duration. The definitive cheiloplasty was performed at 3 months of age using the modified Noordhoff technique. Results: After a follow-up period ranging one to nine years, most patients presented with cosmetically and functionally satisfying results, with an exception of two cases where an undesired peaking effect of the vermilion and dimpling of the vermilion mucosa was encountered. Conclusion: Accessing the anthropometric measurements of fourty non-cleft normal three-month-old infant and using this obtained dara as a guideline, the modified Noordhoff technique can be applied to either complete or incomplete bilaterally cleft lip providing more naturally pleasing and cosmetically satisfying scars that lie in harmony with the philtral ridges, lip tubercle positioned just below the vermilion and a distinct white line and Cupid's bow.

Cleft lip and palate patients often develop maxillary retrusion due to the combined effects of the congenital deformity and the scar tissue after surgical repairs. Maxillary protraction in the cleft patients using orthopedic appliances (i.e. face mask) or distraction osteogenesis during early childhood helps to achieve more balanced skeletal harmony and favorable occlusion for future growth to occur. Kinds, indication, protocol for use of the traditional orthopedic appliances will be discussed. Also the facemask with miniplate system recently developed will be introduced.

Modern orthodontics implies not only occlusal excellence, but also the positioning of teeth to produce optimal facial harmony for the individual patients. Several methods have been used in the study of facial height, width and depth were made from living subjects. These methods, however, complicate to control the subjects, therefore many investigators have used profile cephalometric technics. Practically, cephalometric technics were used m orthodontic treatment, maxillo-facial surgery and anthropometric studies. Author was studied to investigate the normal standards of soft tissue profile in Korean adolescences. The subjects consisted of 53 males and 54 females from 17 to 22 years of age and with normal occlusion and acceptable profile. Aluminum filter was designed to obtain both hard and soft tissue structures on a single film. Eight profile landmarks were plotted and drawn on the tracings of all cephalograms and eighteen depth, height and angles were measured from each landmarks of the cephalograms. The following conclusIOns were obtained from this studies; 1. Total facial convexity was 170. 75 in males and females samples and lower facial and: labiomandibular convexity were each of 141.44, 171.05. 2. Maxillary and mandibular sulcus angulations were 137.61, 129.52 and upper and lower lip inclinations were each of 123.26 and 49.56 in male and females. 3. Soft tissue depth of several points were as follows; Subnasale 18.74㎜ in males and 16.65㎜ in females Pogonion 13.40㎜ in males and 13.07㎜ in females upper lip 14.06㎜ in males and 11.91㎜ in females . lower lip 15.46㎜, 13.63㎜ in males and females 4. The protrusion of nose were 16.28㎜ in males and 15.56㎜ in females 5. The vertical length of upper and lower lips were 25.67㎜, 52.96㎜ and the lip posture was indicated 93.43 per cent (closed state) in centric occlusions.

Esthetic is one of the prime goal of the orthodontic treatment. It is represented by the word of harmony or balance. There is no absolute esthetic norm but it is important to study about it in orthodontic and orthognatic surgical treatment planning. The purpose of this study is to obtain the norm of Korean female adolescents who were candidates of 1986, 1987 Miss Korea Beauty Contest. The 77 individual samples were selected and studied by cephalometric analysis. Obtained results were as follows: 1 Korean esthetic norm was obtained. 2. Simple correlation coefficient was obtained between each measurements. 3. Holdaway ratio of Korean beauty was 3.3 : 1. 4. To compare with caucasian, profile of Korean beauty had less prominant nose, more prominant lip and deeper sulcus depth.

The prosthodontic treatments in maxillary anterior teeth focus on achieving esthetic appearances. It is possible to improve the esthetic appearance by adjusting the shape, arrangement, and color of the maxillary anterior teeth. For anterior teeth restoration, it is necessary to evaluate the relationship of teeth, lip and gingival architecture with the facial profile of patient. Also, clinician needs to fully understand what the patient wants to. DSD (digital smile design) concept can be applied as a tool to improve communication with the clinician, technician and patient. In addition, DSD can help to meet the needs of the patient. In this case, it was impossible to achieve symmetry due to congenital missing of maxillary central incisor. The definitive treatment goal was to get the harmony of maxillary anterior teeth, lip and the patient's face. This case report describes that the patient and clinician got the satisfying esthetic outcome by using DSD.

The purpose of orthodontic treatment is to produce functional occlusion and to create or maintain facial esthetic harmony. The soft-tissue covering of the face also plays an important role in facial esthetics, speech and other physiologic functions. The study of the soft-tissue profile is important for the planning of orthodontic treatment. The author studied cephalometric X-ray films on 49 patients (23boys, 26 girls) with Angle's class II division 1 malocclusion, ranged from 9 to 13 years of age. Roentgenocephalmetric X-ray films were taken pre and post orthodontic care. Tracings were made in usual manner. The obtained results were as follow. 1. There was no significant sexual difference on mean changes. 2. In the comparison of the soft-tissue thickness changes, Ls-Ls' and Si-Si' in male subjects were remarkable. 9. There were significant correlations between osseous (Ss') change and soft-tissue (Ss) chang, of maxilla in male and female subjects subsequent to orthodontic treatment. 4. The ratios between the protraction of the Ss' and that of the Ss were 1:1.5 in all sexes, the ratios between the Si' and that of the Si were 1:1.4 in male and 1:1.2 in female. 5. There were significant correlations between maxillary central incise. angulation change $({\angle}A)$ and upper lip inclination change $({\angle}B)$ in all sexes. 6. There were little correlations between change in distance difference of Is and Ii and change in distance difference of Ls and Li in all sexes in all sexes.
