PURPOSE: Predicting the change in breast size for a specific patient's need is a challenging problem in breast augmentation. We intended to investigate the post-augmentation degree of breast size according to the size of cohesive silicone gel implant. METHODS: To predict post-augmentation breast size, we measured 100 patients' pre-and postoperative 3 month's bust circumference. All patients were performed by total subfascial breast augmentation with moderate profile cohesive silicone gel implant through areolar omega (transareolar-perinipple) incision. RESULTS: According to this study, each additional one pair of 100mL in implant size yielded an approximate 1.5cm increase in bust circumference(p=0.006). CONCLUSION: From this result, we conclude that each additional one pair of 100mL in implant volume yielded about 1.5cm increase in bust circumference. Although this result may not be applied to every patient, we believe that it yields a practical chart that can help to predict the amount of increase in breast size with the use of cohesive silicone gel implant of a specific size preoperatively.

Keloids are benign fibrcus growths which extend beyond the original wound and rarely regress. Available methods of treatment include surgical excision, radiotherapy, intralesional steroid injection, cryotherapy, systemie. chemotherapy, zinc tape strapping, pressure, silicon gel and combined therapy. Postoperative irradiation is a useful and effective method of eradication or prevent.ion of keloid. We describe two cases of the prevention of keloids associated with postoperative irradiation.

PURPOSE: Silicone gel sheet(SGS) is used for preventing and treating keloid or hypertrophic scars. Because the product is weak in tear strength and adherence, it requires several replacements, which requires high cost. As a solution for this problem, we developed a new silicone gel sheet, named as Scar Clinic, and confirmed its physical properties. METHODS: Tensile strength, elongation rate, adhesiveness, and water vapor transmission rate were experimentally compared between the most commonly used SGS product and the Scar Clinic. RESULTS: The newly developed SGS showed better results compared to the existed SGS in regards to tensile strength, elongation rate, adhesiveness, and water vapor transmission rate. CONCLUSION: The Scar Clinic showed higher durability and flexibility. It will be a useful product for treating scars clinically.

A 50-year-old woman visited our hospital for two palpable masses on her sternal and left upper abdominal areas. She had augmentation mammoplasty 12 years prior. Based on the physical examination, the mass in the sternal area was firm, movable, and round. The size of the mass was approximately 3.0x3.0x1.0 cm3. The mass in the upper-left abdomen showed similar characteristics, with a size of approximately 10.0x15.0x1.5 cm3. Ultrasonography revealed a 3.9x1.0x3.4 cm3 hypoechoic lesion in the sternal area. On enhanced-mode computed tomography, a rupture of the left breast implant was noted. Both masses had similar densities as the implant. After rupture of the breast implant, surgery was performed under general anesthesia. Using an inframammary approach, both breast implants and masses were removed using the site of the previous mammoplasty incision. Intraoperative findings revealed that the left breast implant was ruptured and the masses consisted of implant gel components. After surgery, the patient's recovery was uneventful. The patient was discharged without any problem on hospital day 9.

A foreign body granuloma is a non-allergic chronic inflammatory reaction that is mainly composed of multinucleated giant cells. Foreign body granulomas may occur after the administration of any dermal filler. Factors such as the volume of the injection, impurities present in the fillers, and the physical properties of fillers affect granuloma formation. The formation of granulomas involves five phases: protein adsorption, macrophage adhesion, macrophage fusion, and crosstalk. The clinical and pathologic features of granulomas vary depending on the type of filler that causes them. Foreign body granulomas can be treated effectively with intralesional corticosteroid injections. Surgical excisions of granulomas tend to be incomplete because granulomas have ill-defined borders and moreover, surgical excisions may leave scars and deformities.

Silicone gel sheets are widely used to treat keloids and hypertrophic scars. Scarclinic(TM) is a type of silicone gel sheet developed in Korea, and has been shown to improve the appearance of scars. However, Scarclinic(TM) has demerits that include weak adhesiveness, a color that differs from skin, and too great a thickness. Scarclinic-thin(TM) was recently developed with these disadvantages in mind. The purpose of this pilot study was to compare the effects of Scarclinic-thin(TM) and Scarclinic(TM) on scar appearance and wearer's comfort. From April 2010 to May 2010, Scarclinic-thin(TM) and Scarclinic(TM) were applied to treat a single scar in each of 8 patients. One half of each scar was treated with Scarclinic-thin(TM) and the other with Scarclinic(TM). After 3 months, scar quality and wearer's comfort were evaluated using the Vancouver Scar Scale(VSS) and an objective self-assessment scale (OSAS). Mean Vancouver Scar Scale scores for Scarclinic(TM) and Scarclinic-thin(TM) at 3 months were 3.4+/-1.3 and 3.3+/-2.0, respectively, and mean objective self-assessment scale scores were 21.7+/-4.5 and 22.3+/-2.9, respectively. No statistically significant difference was observed between Scarclinic(TM) and Scarclinic-thin(TM) in terms of Vancouver Scar Scale or objective self-assessment scale scores(p=0.83 and 0.70, respectively). Scarclinic-thin(TM) and Scarclinic(TM) are similar in terms of their scar improving effects and wearer's comfort.

The perfect breasts are supposed to be symmetrically balanced and proportionate to the rest of the body with softness, good-position, and mobility to respond to gravity and postural change. But saline filled implants have some disadvantages compared to silicone gel implant. Their low viscosity creates an unnatural feeling and suboptimal aesthetic result, their deflation offers the most important complication such as rippling or size reduction of breast. Therefore precise preoperative design, exact procedure and appropriate postoperative care are essential to optimal result. In past 5 years, we have performed the transaxillary subpectoral augmentation mammaplasty using saline filled implants on 183 female patients whose breasts were hypoplastic and followed up 58 months maximally. All patients were assisted with endoscopy. We employed round, textured type implant with the size ranging from 120cc to 270 cc and overinflated them 10 to 20% beyond its original volume. The overall result was satisfactory but some cases of capsular contracture, deflation, implant displacement and infection were found. On the basis of our experience, we suggest some critical points so as to obtain the best result: what conforms to the patients anatomy and satisfies her goal at the same time. First of all, preoperative design in accordance with the dimension is very important. The best dimension for each patient depends on the definition of the ideal base width of the breast. Secondly, exact subpectoral dissection using endoscopy, no-touch technique for the implant is essential to achieve excellent results. Finally, postoperative self management must not be ignored.

BACKGROUND: Keloid is one of the most frustrating clinical problems in wound healing. There are numerous treatments for keloids such as surgical excision, steroid injection, radiation therapy, laser, silicone gel application and so on. Surgical excision of a keloid is generally not accepted as a first treatment of choice. However, there have been many reports of successful cosmetic results from specialized surgical treatments such as intra-lesional/intra- marginal excision with or without post surgical adjuvant treatments. OBJECTIVE: The aims of this study areto evaluate the effectiveness of intralesional excision of keloids, the optimal surgical conditions and the proper adjuvant therapy after surgery. METHODS: We analyzed the medical records and clinical photographs of 20 patients who underwent intra-lesional excision of their keloids and who had regular follow-ups for at least for 3 months. The clinical outcomes were assessed by three independent physicians based on their interpretation of the photographs before and after surgery with using a global assessment 5 point scale that ranged from bad, poor, fair and good to excellent. RESULTS: General surgical outcomes after intra-lesional excision: the average improvement score was 4.05 after intra-lesional excision and adjuvant therapy. The average improvement score after intra-lesional excision was 4.71 for ear keloids and 2.83 for keloids in other areas (p=0.000). The average improvement score after intra-lesional excision was 5 for earlobe keloids and 4.42 for ear-helix keloids (p=0.014). The average improvement score was 3.92 for the steroid intra-lesional injection and topical silicone gel combination treatment group after intra-lesional excision and the average improvement score was 4.29 for the single topical silicone gel treatment group (p=0.858). CONCLUSION: Although surgery is not a first treatment of choice for the management of keloids, large recalcitrant keloids need massive surgical removal for faster clinical results. In this study, we found that surgery, and especially intra-lesional excision, is not an absolute contraindication for treating keloids and this is sometimes considered as the first treatment of choice, and especially for ear keloids. However, a more careful surgical approach is necessary for the case of keloids that develop in other areas. Further studies about the optimal surgical indications for keloids and the recommended adjuvant therapy after surgery are necessary.
