PURPOSE: A Tessier classification number 7 cleft is an uncommon malformation that results from a failure of mesenchymal fusion within the maxillary and mandibular prominences of the 1st pharyngeal arch. Many operative techniques of the number 7 cleft repair have been proposed to restore function and improve aesthetics. Fifteen patients underwent repair of a number 7 cleft over 13 years by a modification of the surgical Technique, and an appraisal of the operative outcome is reported herein. METHODS: A retrospective review was conducted involving 15 patients with number 7 clefts who underwent surgery from 1996 to 2009. The changes in surgical technique included skin closure, attachment of the orbicularis oris muscle, and position of the repaired commissure; the changes were analysed with a review of the medical records and the outcomes of surgery were analysed via photographs. Specifically, the technique of skin closure was changed from the a Z-plasty to a linear closure, the orbicularis oris muscle overlapped attachment was replaced by a side-to-side approximation with horizontal mattress sutures, and the position of the repaired commissure was changed from 1mm laterally to 1mm medially in reference to the non-cleft side. RESULTS: A Z-plasty caused additional cutaneous scarring, an overlapped attachment of the orbicularis oris muscle caused a thick oral commissure, and the repaired commissure migrated to the lateral side, so a 1mm, laterally-positioned commissure caused asymmetry. The altered procedure included a linear skin closure, a side-to-side orbicularis oris muscle approximation, and a 1mm, medially-positioned commissure, which together resulted in a good outcome. CONCLUSION: The altered procedure for repair of a number 7 cleft as described herein, yields a short scar, no functional problems with the orbicularis oris muscle, a thin oral commissure, and symmetry of the repaired commissure.

PURPOSE: Deficiencies of the abdominal wall can be the a result of infection, surgery, trauma, or primary herniation. For abdominal wall reconstruction, synthetic materials have been shown to provide a better long-term success rate than primary fascial repair. But, synthetic materials cannot elicit angiogenesis or produce growth factor and are therefore plagued by an inability to clear infection. As a result of the inherent drawbacks of synthetic, significant effort has been spent on the identification of new bioprosthetic materials. The aim of our study is to evaluate the effectiveness of a synthetic material(PROCEED(R)) and an ADM(SureDerm(TM)) to repair abdominal wall defects in a rabbit models. METHODS: We measured the tensile strength of the SureDerm(TM) and PROCEED(R) by a Tension meter(Instron 4482). 16 Rabbit models were assigned to this study for abdominal wall reconstruction. Abdominal defect of 8 rabbits were reconstructed by PROCEED(R) and the rest were reconstructed by SureDerm(TM). We assessed gross and histologic examinations for the reconstructed abdominal wall. RESULTS: The tensile strenth of SureDerm(TM) and Gore Tex(R) is 14.64+/-0.51 Mpa, 8.54+/-0.45 Mpa. PROCEED(R) was estimated above the limits of measurement. Inflammatory reaction of PROCEED(R) persisted for 32weeks, but SureDerm(TM) decreased after 16weeks. Vascular ingrowth into the SureDerm(TM) was seen after 32 weeks. The basement membrane of SureDerm(TM) changed into a form of pseudoperitoneum. In PROCEED(R), it seemed like pseudoepithelial lining was made from the fibrosis around the mesh. CONCLUSION: In our study, the SureDerm(TM) not only have less inflammatory reaction and presented more angiogenesis than the PROCEED(R), but also have pseudoperitoneum formation. It is expected that SureDerm(TM) is useful for abdominal wall reconstruction. However, a long-term study of its usage consequences are thought to be needed.

PURPOSE: Stem cells continue to receive research attention in the clinical fields, and adipose-derived stem cells(ADSCs) have been shown to be a good source raw material. Many plastic surgeons are researching the ADSC adipogenesis with a view of conducting clinical trials, and many attempts have been made to identify the factors that promote the adipogenesis of ADSCs, but comparatively few correlation studies have been undertaken to explore the relation between reactive oxygen species(ROS) and the ADSC adipogenesis. We undertook this study is to investigate the effects of ROS on ADSC adipogenesis. METHODS: ADSCs were isolated and cultured from abdominal adipose tissue, and cultured in different media; 1) DMEM(control), 2) adipogenesis induction culture medium, 3) adipogenesis induction culture medium with ROS(20 microM/50 microM H2O2), 4) adipogenesis induction culture medium containing ROS(20 microM/50 microM H2O2) and antioxidant(10 microM/20 microM Deferoxamine). We compared adipogenesis in these different media by taking absorbance measurements after Oil-Red O staining every 5 days. RESULTS: After culturing for 20 days, significant differences were observed between these various culture groups. Absorbance results showed significantly more adipogenesis had occurred in media containing adipogenesis induction culture medium and H2O2(in a H2O2 dose-dependently manner) than in media containing adipogenesis induction culture medium and no H2O2(p<0.001). Furthermore, in media containing adipogenesis induction culture medium, H2O2, and antioxidant, absorbance results were significantly lower than in adipogenesis induction culture medium and H2O2(p<0.001). CONCLUSION: These findings suggest that ROS promote the adipogenesis of ADSCs. We suggests that ROS could be used in the adipose tissue engineering to improve fat cell differentiation and implantable fat tissue organization.

4.Necrotizing Fasciitis in a Patient with Systemic Lupus Erythematosus.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2011;38(3):309-314
PURPOSE: Necrotizing fasciitis is a life-threatening, destructive soft tissue infection with a very high rate of mortality that needs early diagnosis and aggressive treatment. Systemic Lupus Erythematosus(SLE) is a systemic, autoimmune disease and it's major cause of mortality is an infection. But necrotizing fasciitis in SLE is very rare and there have been only 22 cases reported in the literatures. We reported a patient of necrotizing fasciitis with SLE and reviewed 22 others from literature research. METHODS: A 40-year-old female patient with a history of SLE for 6 years came to the emergency room. The patient complained of severe pain and swelling on her right leg. She was diagnosed as necrotizing fasciitis and underwent emergency fasciotomy. As wound cultures showed variable organisms, she was treated with broad-spectrum antibiotics and underwent several surgical debridements. Then, the wound was treated with the V.A.C(Vacuum Assisted Closure) device and split thickness skin grafting was performed two times. RESULTS: Skin graft was well taken within 2 weeks after operations and the patient was discharged to outpatient follow up. There was no complication related with surgery and she could walk without cane after 3 months. CONCLUSION: We treated a necrotizing fasciitis in a patient with SLE and reviewed 22 others from literature research. The case presented here suggests that necrotizing fasciitis is a rare disease in SLE patients, but should be considered in the differential diagnosis of soft tissue infection in SLE patients. A high index of suspicion is needed for early diagnosis and proper management in these patients.

PURPOSE: The goal of reduction mammaplasty is breast with natural cone shape, minimizing scars, well-placed and sensate nipple-areolar area and maintaining breast physiology. In order to satisfy that goal, variable reduction mammaplasty methods are performed, however, two methods such as vertical reduction method and inverted T-scar method are currently most used. We compared indications and advantages of the two methods and set up useful guidlines. METHODS: For 15 years from 1995 to 2010, we experienced 84 patients(162 breasts). We performed vertical reduction method as Lejour's superior pedicle technique(45 patients) and inverted T-scar method as Goldwyn's inferior dermal flap technique(39 patients). We evaluated the result of the operation comparing patient's age, amount of resected tissue, complications and post-operative scars of the two methods. RESULTS: The mean age was 36 years and the vertical reduction group was 3 years younger than inverted T-scar group. The mean breast tissue resection amount per one breast, inverted T-scar group(712 gm) was lagger than vertical reduction group(395 gm). CONCLUSION: There is no ideal method for reduction mammaplasty until now. However, we suggest that guide line, the vertical reduction method is effective for minimal and moderate macromastia in young and middle aged women and inverted T-scar method is appropriate for severe macromastia with ptosis in elderly women. Recently, all procedures tried shorter and smaller scar on the vertical line as small I, J or L shape scar, and inframammary fold as short inverted T-scar.

6.The Shape and the Location of Forehead Hairline of Korean Males in Their 20s & 30s.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2011;38(3):295-299
PURPOSE: It is generally believed that alopecia is caused by various factors such as scars, stress, genetical factors, androgens, etc. Androgenic alopecia is one of the most common cause of alopecia and found mainly in males. Propecia(Merck & Co., USA) and Minoxidil(McNEIL-PPC, Inc, USA) were the drugs approved from FDA for treatment of androgenic alopecia. Surgical treatments such as flap, tissue expansion, scalp reduction and hair transplantation can be considered if necessary. Hair micrograft techniques were developed for natural hair shapes and minimal adverse effect. There were attempts to measure the length of the forehead of the Korean young adults. However attempts to classify the shape and location of forehead hairline were rare. This study attempted to find out standard hairlines of young adults in their 20s & 30s and the result would be the guideline of the hairline in hair replacement surgery of male patients in their 40s & 50s. METHODS: 200 male adults in 20s and 30s were photographed and measured the length of 11 vertical index lines to determine hairline. The indexes are the distances from hairline to intercanthal midpoint(A), to medial canthus (B), to upper eyelid fissure(C), to lower eyelid fissure(D), to lateral canthus(E) and distance from lateral highest point to medial lowest point, if the hairline is M-shape(F). Additionally, we classified the hairlines into 4 groups, M, horizontal, inverted U and irregular shapes. RESULTS: The most common hairline of male adults in their 20s is inverted U-shape(53.3%), followed by horizontal-shape, M-shape, irregular-shape. In their 30s, inverted U-shape(59%) is followed by irregular-shape, M-shape, horizontal-shape. The M-shape is more frequently found in males in 30s than those in 20s. The mean values of the indexes in their 20s are as follows: A(76.14mm), B(Rt: 75.78mm, Lt:76.41mm), C(Rt: 69.43mm, Lt: 69.92mm), D(Rt: 76.92mm, Lt:77.46mm), E(Rt: 64.16mm, Lt: 64.73 mm), F(4.09mm). Those in their 30s are as follows: A(76.13mm), B(Rt: 76.114mm, Lt: 76.02mm), C(Rt: 69.87 mm, Lt: 70.37mm), D(Rt: 77.37 mm, Lt: 77.58mm), E(Rt: 69.63mm, Lt: 69.85mm), F(6.14 mm). CONCLUSION: The knowledge about human body measurement is indispensable to plastic surgeons. In this study, inverted U shape is the most common type of hairline in 30s, and similar distribution is found in 20s. The percentage of M shape in their 30s is elevated more than 10% compared to that in their 20s. The study of hairline shapes and 11 indexes of hairlines can be useful for planning of the hair transplantation and postoperative evaluation. This study being based on photogrammetry, there may be differences between actual distance of curved face and projected distance on flat photographs.

Journal of the Korean Society of Plastic and Reconstructive Surgeons 2011;38(3):287-294
PURPOSE: Reduction malarplasty is one of the common aesthetic procedures performed in the Orient. We have analyzed effective operative methods according to the pivot point for the osteotomy and reposition of the zygoma for reduction malarplasty after confirming the shapes of the individual zygomas. METHODS: Thirty-six patients had been received malarplasty over the last 10 years. The average follow-up period was 16 months. We categorized the patients into three groups according to their prominent appearance features. Group I had a prominently protruded zygomatic body, group II had a prominently protruded zygomatic arch, and group III had a prominently protruded body and zygomatic arch. In the group I, two parallel oblique osteotomies on the body, the middle portion was removed, and with the zygomatic arch as the pivot point, the body was repositioned inwards. In the group II, the zygomatic body and arch osteotomy is performed, with the body as the pivot point, and the arch is depressed medially. In the group III, using the two aforementioned methods, the zygoma was repositioned medially. In each case, postoperative complications and patients satisfaction over the surgery were surveyed. RESULTS: Each group had 25, 5 and 12 patients respectively. No significant complications were found except for one patient who experienced a non-union of zygomatic bone. In the case of group I, four patients underwent a secondary operation. CONCLUSION: Reduction malarplasty is popular as an effective facial contouring surgery. In order to obtain more effective results,however, the zygomatic shape should be identified, and appropriately repositioned by different operative technique according to pivot points.

PURPOSE: Chin is located in a prominent position, and is important to balance and harmony of the face. Genioplasty is widely performed with patients' high satisfaction, yet being relatively simple procedure. Recently in analysis of dentofacial trait, three rotational variables of yaw, pith, and roll are considered with three translational variables(forward/backward, up/down, right/left). And we could correct chin deformity effectively by applying the three rotational variables with three translational variables in genioplasty. METHODS: Twenty-eight patients who have chin deformity underwent osseous genioplasty. Preoperative photography, facial three dimensional computed tomography, and cephalography were taken while chin deformities were accessed. The chin deformity was classified into four categories; macrogenia, microgenia, asymmetric chin deformity, and combined chin deformity groups. According to the nature of chin deformities and the patients' desire, preoperative plans were formulated, in consideration of three rotational variables and translational variables. Through intraoral approach, anterior mandible was exposed in the subperiosteal plane between the mental foramens and beneath the mental foramens. In the anterior mandible, vertical and horizontal grid lines with 5mm intervals were marked to confirm the spatial location of osteomized bone segment after osteotomy. Chin repositioning was done in consideration of axial rotation and planar translation. RESULTS: Most of the patients had achieved satisfactory results with few complications. By considering the three rotational variables, it was possible to make the chin repositioning effectively. One of the patients complained about insufficient chin correction. In other case, persistent sensory impairment around chin was observed. CONCLUSION: In conclusion, it is worthwhile to apply preoperative analysis and operative procedures in consideration of a three rotational variables with three translational variables in genioplasty.

PURPOSE: It has always been an aspiration for Asians to look more balanced and feminine, considering their facial features regarding relatively flat midface with marked prominences of the zygoma. Many studies have been dealt in this subject. However, the authors would like to emphasize the concept and introduce the technique of repositioning of the malar complex to a cosmetically beneficial point and stationing it on proper position by fixation on zygoma body and arch. METHODS: From January 1998 to December 2007, this method was performed in 50 patients of mild to moderate prominence and malposition of the malar complex. A simplified technique of lateral orbital osteotomy and oblique osteotomy on zygomatic arch through intraoral and preauricular incision was developed. Then, liberal malar complex can be moved to a supero-posterior direction and repositioned to a more cosmetically beneficial point. To maintain the stationed position and to protect from vector affected by the attached masticating muscle to zygomatc bone, fixation was done on both zygoma body and arch. RESULTS: We have obtained satisfactory results using this procedure without any observable complications. The advantages of this procedure are proper exposure, inconspicuous scar, safe, more natural contour, improved stability, and shorter healing time. CONCLUSION: The authors suggest that reduction malarplasty should be approached with underlying concept of repositioning and fixation. In mild moderate malar prominent cases, our technique will provide with maintenance of aesthetic concept, equal to the malar reduction performed under coronal approach and provide with more natural facial contour with stability even with less invasive surgical approach.

10.The Relationship between Socioeconomical Status and Incidence of Facial Bone Fracture.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2011;38(3):263-272
PURPOSE: The human face is the most exposed part of the body, and in patients with simple or complex trauma from traffic accidents, industrial calamities, sports injuries, human assaults, and daily accidents, facial trauma occupies an important portion. The etiology of facial trauma vary on a society's economic, cultural, and environmental status. METHODS: Regarding patients who were admitted from between the years 2000 to 2009 at the Hanyang University hospital, the authors studied how the changes in the economic status in the past 10 years of our country influences the incidence of facial bone fractures. RESULTS: In this study, 1) The unemployment rate showed a strong negative relationship with the total number of inpatients with facial bone fractures, the number of male patients, the number of female patients, the number of patients with facial bone fractures caused by fall down, the number of patients who were admitted for shorter than 7 days, and the number of the facial bone fracture patients with their age in the twenties. 2) The consumer price index showed a strong positive relationship with the number of female patients, the number of patients who were admitted for shorter than 7 days, and the number of the facial bone fracture patients with their age in the teens and fifties. CONCLUSION: Looking at the results of correlation analysis and multiple regression analysis with economic indicators, the unemployment rate showed negative influence to the total number of inpatients with facial bone fractures, and the number of inpatients with facial bone fractures caused by fall down, with statistical significance.
