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.

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.

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.

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.

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: Nipple-sparing mastectomy (NSM) is gaining popularity due to its superior aesthetic results. When reconstructing the breast with free abdominal tissue transfer, we must readdress the recipient vessel, because NSM can cause difficulty in access to the chest vessel. METHODS: Between June 2006 and March 2011, a total of 92 women underwent NSM with free abdominal tissue transfer. A lateral oblique incision was used for the nipple-sparing mastectomy. For recipient vessels, the internal mammary vessels were chosen if the mastectomy flap did not block access to the vessels. If it did, the thoracodorsal vessels were used. Age, degree of breast ptosis, weight of the mastectomy specimen, and related complications of the internal mammary vessel group and the thoracodorsal vessel group were compared. RESULTS: Thoracodorsal vessels were used as recipient vessels in 59 cases, and internal mammary vessels in 33 cases including 4 cases with perforators of the internal mammary vessels. Breast reconstruction was successful in all cases except one case involving a total flap failure, which was replaced by a silicone gel implant. The internal mammary group and the thoracodorsal group were similar in terms of age, height, breast weight, and degree of ptosis. The flap related complications such as flap loss and take-back operation rates were not significantly different between the two groups. The rate of nipple necrosis was higher in the internal mammary group. CONCLUSIONS: The thoracodorsal vessels could produce comparable outcomes in breast reconstruction after nipple-sparing mastectomies. If access to internal mammary vessels is difficult, the thoracodorsal vessel can be a better choice.
