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: The main problem for reoperation after augmentation mammoplasty is contraction of the capsule surrounding a breast implant and it tends to be recur after second surgery. The author studied that intracapsular injection of triamcinolone could reduce the recurrence of capsular contracture. METHODS: Twenty-six cases of capsular contracture, undertaken at the M.D. Clinic between July 2002 and August 2004, were reviewed. Age, types of previous implant, reoperation methods including triamcinolone injection, and recurrence rates were retrospectively evaluated. RESULTS: Two cases (7.7%) were in their twenties, 14 (53.9%) in their thirties, 7 (26.9%) in their forties and 3 (11.5%) in their fifties. The types of previous implant were as followed: 24 (92.3%) saline, 2 (7.7%) silicone gel, 14 (53.9%) textured type and 12 (46.1%) smooth type. The reoperation methods were as followed: capsulectomy in 4 (15.4%), subpectoral conversion in 1 (3.9%), subpectoral conversion with an intracapsule injection of triamcinolone in 2 (7.7%), capsulotomy in 7 (26.9%) and capsulotomy with an intracapsule injection of triamcinolone in 12 (46.2%). Recurrence occurred in 1 capsulectomy (25%), 1 subpectoral conversion (100%), 0 subpectoral conversion with injection (0%), 4 capsulotomy (57%) and 1 capsulotomy with injection (8.3%). CONCLUSION: The injection of triamcinolone into the capsule following an implant replacement was effective in patients with a capsular contracture after augmentation mammoplasty. It seems to be an effective rational therapy for primary high risk cases with more advanced technique.

If autogenous nail is lost in nail bed injuries, alternative effective nail bed protection material is questionable in postoperative follow up period. The conventional modality with autogenous nail coverage have several disadvantages such as drawback of maintenance, higher chance of loss and complex dressing step (eg. ointment apply for humidification and nail fixation using tape or bandage). So, we have studied the usefulness of adhesive silicone gel sheet for alternative nail bed protection material until the end of nail regeneration. From March 2003 to July 2004, we have experienced 215 traumatic nail bed injuries except fingertip loss. Among these patient, we classified two groups, 30 cases with autogenous nail protection(Group I) and 30 cases with adhesive silicone gel sheet protection(Group II). Mean full nail growth time was 3.6 months in group I and 3.8 months in group II. Mean final nail appearance score(0: poor, 4: excellent) was 3.0 in group I and 3.5 in group II. Adhesive silicone gel sheet protection(Group II) was slightly superior to the autogenous nail protection in final appearance, especially sterile matrix laceration. In conclusion, we believe that adhesive silicone gel sheet application is a simple, acceptable, alternative method for protecting nail bed with loss of autogenou nail. It has a number of advantages compared with autogenous nail such as better humidification, controllable hygiene, less pain, less hospitalization, less frequent visit, less chance of loss, avoiding complex dressing step and more even pressure with adhesiveness, flexibility and durability.

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.

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.

BACKGROUND: Rupture is an important complication of breast implants. Before cohesive gel silicone implants, rupture rates of both saline and silicone breast implants were over 10%. Through an analysis of ruptured implants, we can determine the various factors related to ruptured implants. METHODS: We performed a retrospective review of 72 implants that were removed for implant rupture between 2005 and 2014 at a single institution. The following data were collected: type of implants (saline or silicone), duration of implantation, type of implant shell, degree of capsular contracture, associated symptoms, cause of rupture, diagnostic tools, and management. RESULTS: Forty-five Saline implants and 27 silicone implants were used. Rupture was diagnosed at a mean of 5.6 and 12 years after insertion of saline and silicone implants, respectively. There was no association between shell type and risk of rupture. Spontaneous was the most common reason for the rupture. Rupture management was implant change (39 case), microfat graft (2 case), removal only (14 case), and follow-up loss (17 case). CONCLUSIONS: Saline implants have a shorter average duration of rupture, but diagnosis is easier and safer, leading to fewer complications. Previous-generation silicone implants required frequent follow-up observation, and it is recommended that they be changed to a cohesive gel implant before hidden rupture occurs.

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.
