Recently, as custom-made demand about female underwear is increased, securing of a various dimension system is urgent, and satisfaction of each customer cannot be heightened with established dimensions. If we could measure shape of a living body with a fast and simple method, the custom-made demand of customers could be satisfied in the underwear as well as a clothing industry by using the method. One of the alternatives is shape measurement of the living body by a Moire fringe method. If we put a grating in front of an object to be measured and illuminate light, a Moire fringe with contour line shape is generated in the object, so we can conveniently measure object shape without touching directly by using the pattern. The Moire fringe and three-dimensional shape of the breast of the living body was acquired by a PMP method using a polygon mirror, and height and bottom width of the breast of the living body were measured by using obtained data in this study. Data of breast shape measurement through a mannequin was collected in a previous step as basic material for measuring the breast shape measurement of the living body. Three women in the twenties were selected as one of methods for measuring breast shape of a woman. As a result of the breast shape measurement of a living body A, it was measured that height of the breast was about 67.24mm and the bottom width was $13781.60mm^2$. This study is expected to contribute for collecting basic data of a female underwear industry and establishing a specification of a dimension system.

Purpose: We evaluated the motion-induced dosimetric effects on the field-in-field (FIF) technique for whole-breast irradiation (WBI) using actual patient organ motion data obtained from cine electronic portal imaging device (cine EPID) images during treatment. Materials and Methods: Ten breast cancer patients who received WBI after breast-conserving surgery were selected. The static FIF (SFIF) plan involved the application of two parallel opposing tangential and boost FIFs. To obtain the amplitude of the internal organ motion during treatment, cine EPID images were acquired five times for each patient. The outside contour of the breast (OCB) and chest wall (CW) contour were tracked using in-house motion analysis software. Intrafractional organ motion was analyzed. The dynamic FIF (DFIF) reflecting intrafractional organ motion incorporated into the SFIF plan was calculated and compared with the SFIF in terms of the dose homogeneity index (DHI_90/10) for the target and V₂₀ for the ipsilateral lung. Results: The average motion amplitudes along the X and Y directions were 1.84±1.09 mm and 0.69±0.50 mm for OCB and 1.88±1.07 mm and 1.66±1.49 mm for CW, respectively. The maximum motion amplitudes along the X and Y directions were 5.53 and 2.08 mm for OCB and 5.22 and 6.79 mm for CW, respectively. Significant differences in DHI_90/10 values were observed between SFIF and DFIF (0.94 vs 0.95, P<0.05) in statistical analysis. The average V₂₀ for the lung in the DFIF was slightly higher than that of the SFIF in statistical analysis (19.21 vs 19.00, P<0.05). Conclusion: Our findings indicate that the FIF technique can form a safe and effective treatment method for WBI. Regular monitoring using cine EPID images can be effective in reducing motion-induced dosimetric errors.

Purpose: As a rare congenital anomaly, Poland's syndrome has been known to show hypoplasia in breast and nipple, absence of pectoralis major muscle, and aplasia or deformity of rib or costal cartilage which has been reported to be more common in male. However, most patients who are seeking operation are female patients having one-side deformity. In the field of plastic surgery, the major surgical indications could be asymmetric chest wall depression in man or breast hypoplasia in woman. There are many reconstruction options according to the degree of patient's deformity: a prosthetic implant, breast implant with or without tissue expander, latissimus dorsi musculocutaneous pedicled flap with or without implant and/or tissue expander, and free tissue transfer with or without tissue expander. Methods: The authors have treated 4 patients(2 male, 2 female) who had a diagnosis of Poland's syndrome. According to the degree of patient's deformity, all patients underwent correction of breast asymmetry and unilateral anterior thoracic hypoplasia with one-staged or two-staged reconstruction. Results: All patents were satisfied with the results and there occurred no specific complications. Conclusion: The authors propose the treatment plan for patient with Poland's syndrome, according to the degree of patient's deformity. In case of male patient with mild deformity, the prosthetic implant or latissimus dorsi musculocutaneous pedicled flap will simulate the missing pectoralis and improve the contour deformity. In case of female patient with moderate to severe breast asymmetry and upward displaced nipple areolar complex (NAC), NAC can be lowered with tissue expander, breast can be enlarged with autologous free flaps or latissimus dorsi musculocutaneous pedicled flap with implant.

Osteochondroma arising from the rib is rare. They arise as bony outgrowths from the rib and extend either extrathoracically into the subcutaneous plane or intrathoracically compressing the lung or mediastinal structures. A 23-year-old male patient presented with complaints of breast lump since last year. On clinical examination, a hard bony projection with lobulated contour was palpable. Chest radiograph and contrast-enhanced CT showed a bony outgrowth arising from the anterior aspect of costochondral junction of the right fourth rib with displacement of pectoralis major muscle anteriorly. Osteochondroma should be considered as a differential diagnosis in the presentation of hard lump in the breast along with other chest wall tumors.

Purpose: Together with the breast, buttocks are an important element of attractive body contour. To make a beautiful buttocks, improvement of body contour around the buttock as well as buttock augmentation and lifting is also important. The authors investigated characteristic features of buttocks in Koreans and report about the results of liposculpture and autologous fat injection for improving buttock's contour. Methods: We performed a retrospective study of 21 patients who would like to gluteal reshaping. We checked about buttock's ptosis, projection, depression, gluteal retraction and excessive fat accumulation around buttocks. Depending on it, we performed liposculpture and autologous fat injection. Under general anesthesia, we harvested fat from excessive fat accumulation areas around buttocks, and injected into buttocks medio-superiorly. Postoperatively, pillows were positioned on the bed not to press the buttocks which were injected with the fat. Results: Based on the shape of buttocks, A-shape is seen in 4 cases (19%), V-shape 3 cases (14%), squareshape 9 cases (43%), round-shape 5 cases (24%). Based on the Gonzalez's ptosis grading method, 1 degree ptosis is 1 case (4%), 2 degree ptosis is 6 cases (29%), 3 degree ptosis is 8 cases (38%), 4 degree ptosis is 6 cases (29%). There were no complications such as infection, hematoma, pain, dysparethesia. The subjective assessment of surgical results by patients was excellent. Conclusion: To make a beautiful buttock, improvement of body contour around the buttock as well as buttock augmentation and lifting is also important. Liposculpture and autologous fat grafting are very safe, useful and easy methods for improving buttock's contour.

Background Autologous fat graft has become a useful technique for correction of acquired contour deformity in reconstructed breasts. However, there remains controversial regarding the efficacy and safety of the practice for reconstructive breast surgery. Methods A retrospective review was performed on 102 patients who had secondary fat grafting after breast reconstruction. Fat harvest, refinement and injection were done by Coleman's technique. All patients were followed up postoperatively within 1 month and after 6 months including physical examination and ultrasonography. In 38 patients, the reabsorption rate was calculated by serial changes of thickness between skin and pectoral fascia in the ultrasonic finding. Locoregional recurrence rate was compared with control group of 449 patients who had breast reconstruction without fat graft in the same time period. Results Average 49.3 mL fat was injected into each breast. The most common location of fat graft was upper pole, followed by axilla, lower and medial breasts. During 28.7 months of average follow-up period, 2.9% of total patients had symptoms of palpable mass on fat graft side and ultrasonography identified fat necrosis and cyst formation in 17.6% of the patients. Calculated fat reabsorption rate was 32.9%. Locoregional recurrence was occurred in 1 patient (0.9%) and the rate was not different significantly with control group (2%). Conclusions Although further studies are required to provide surgeons with definitive guidelines for the implementation of fat grafting, we propose autologous fat graft is an efficient and safe technique for secondary breast reconstruction.

Purpose: The success rate of free flap operation has shown a recent increase. Especially for breast reconstructive patients, aesthetic results are considered a necessity. However, for patients who underwent reconstruction in parts of the body other than breast, for example, head and neck, lower and upper extremities, aesthetic considerations are underscored. Nowadays, however, aesthetic standpoint toward these patients is changing. Materials and Methods: We conducted a retrospective review of 8 patients who underwent secondary procedures after free flap surgery from March of 2011 to April of 2014. Results: Secondary refinement was a safe and less time-consuming technique for maximizing the function and aesthetic appearance for the patient. Conclusion: Appearance has become increasingly important with regard to function and quality of life. Therefore, for free flap reconstructive patients, secondary refinements may be considered in order to change the shape and contour. The secondary refinements are critical to the final result and must be a planned part of the entire reconstructive sequence.

The goal of reduction mammaplasty is a breast with natural contour and volume, aesthetically situated scars, and a well-placed, sensate nipple and areola. The most successful techniques achieve this through the excision of tissue from the lower part of the breast based on some variation. However, the Mckissock's vertical bipedicle technique is the popular method for reduction mammaplasty. As an alternative modified Mckissock's method, we have found the use of only an inferior dermal flap with a keyhole pattern to be a simple and safe method for obtaining satisfactory aesthetic results. We have used inferior dermal flap for 4 patients recently and obtained the advantages as below compare to the Mckissock's method. 1. Rich blood supply to the broad based inferior flap. 2. More easy transposition of the nipple and areola. 3. More good operation field for resection of breast tissue. 4. Short operation time. 5. Can applied to the gigantomastia.

Purpose: The method of using ultrasound-assisted liposuction and excision of the remaining glandular tissue is the preferred method for treating gynecomastia and is currently used worldwide. Herein, this article described the role of ultrasound-assisted liposuction before a surgical excision in the treatment of gynecomastia. The cosmetic results were objectively evaluated. Methods: 11 patients (22 breasts) underwent ultrasoundassisted liposuction and suction-assisted lipectomy between April 2007 and January 2009. At the end of the liposuction, the remaining glandular tissue was removed through the incision used for liposuction. We evaluated the cosmetic results using ordinary scale methods on the basis of four categories (recurrence, symmetry, contour irregularity, and scar). Results: The volume of aspirates ranged between 50 and 200 cc per breast and the average weight of tissue removed by excision was 65g per breast. No complications were recorded. Regarding the cosmetic evaluation, the recurrence, contour irregularity, and scar were excellent, the symmetry was good, and the overall results represented all those cases were mostly excellent. Conclusion: Ultrasound-assisted liposuction has many advantages in the treatment of gynecomastia. When excising the remaining glandular tissue, bleeding is decreased by the use of a tumescent technique. The glandular tissue is easily mobilized and excised after being "morselized" with ultrasound-assisted liposuction. The glandular tissue is simply dissected via the suction surface. Compared the residual mound of glandular tissue beneath the nipple and areola to the periphery, it facilitates precise control of the excision.

Background Implant-related deformities in aesthetic rhinoplasty are a major problem for rhinoplasty surgeons. Capsular contracture is believed to be the pathological cause of delayed contour deformities, comparable to breast implant-related contracture. This study investigated the prevalence of bacterial biofilms and other epidemiological factors related to capsular contracture in cases of silicone augmentation rhinoplasty. Methods Thirty-three patients who underwent corrective rhinoplasty due to a delayed contour deformity or aesthetic revision after implant rhinoplasty were studied from December 2014 to December 2016. All recruited patients received surgical correction by the authors. The patients were categorized by clinical severity into four grades. Demographic data and related confounding factors were recorded. Samples of capsular tissue and silicone removed from each patient were analyzed for the presence of a biofilm by ultrasonication with bacterial culture and scanning electron microscopy. Results Thirty-three paired samples of capsular tissue and silicone implants from the study group were analyzed. Biofilms were detected in one of 10 subjects (10%) with grade 1 contracture, two of four (50%) with grade 2 contracture, 10 of 14 (71.40%) with grade 3 contracture, and four of five (80%) with grade 4 contracture (P<0.05). The organisms found were Staphylococcus epidermidis (47.10%), coagulase-negative staphylococci (35.30%), and Staphylococcus aureus (17.60%). Conclusions As with breast implant-related capsular contracture, silicone nasal augmentation deformities likely result from bacterial biofilms. We demonstrated the prevalence of biofilms in patients with various degrees of contracture. Implant type and operative technique seemed to have only vague correlations with biofilm presence.
