BackgroundFor patients with full thickness skin defects, autologous Split-thickness skin grafts (STSG) are generally regarded as the mainstay of treatment. However, skin grafts have some limitations, including undesirable outcomes resulting from scars, poor elasticity, and limitations in joint movement due to contractures. In this study, we present outcomes of Matriderm grafts used for various skin tissue defects whether it improves on these drawbacks.MethodsFrom January 2010 to March 2012, a retrospective review of patients who had undergone autologous STSG with Matriderm was performed. We assessed graft survival to evaluate the effectiveness of Matriderm. We also evaluated skin quality using a Cutometer, Corneometer, Tewameter, or Mexameter, approximately 12 months after surgery.ResultsA total of 31 patients underwent STSG with Matriderm during the study period. The success rate of skin grafting was 96.7%. The elasticity value of the portion on which Matriderm was applied was 0.765 (range, 0.635-0.800), the value of the trans-epidermal water loss (TEWL) was 10.0 (range, 8.15-11.00) g/hr/m2, and the humidification value was 24.0 (range, 15.5-30.0). The levels of erythema and melanin were 352.0 arbitrary unit (AU) (range, 299.25-402.75 AU) and 211.0 AU (range, 158.25-297.00 AU), respectively. When comparing the values of elasticity and TEWL of the skin treated with Matriderm to the values of the surrounding skin, there was no statistically significant difference between the groups.ConclusionsThe results of this study demonstrate that a dermal substitute (Matriderm) with STSG was adopted stably and with minimal complications. Furthermore, comparing Matriderm grafted skin to normal skin using Cutometer, Matriderm proved valuable in restoring skin elasticity and the skin barrier.

Background Endoscopic forehead lifting is one of the most common procedures in the field of upper facial surgery. The upper third of the face determines the facial expression and plays a key role in the appearance of facial youth. After the forehead, a high hairline is one of the most important features of the upper third of the face contributing to age identification. The combined evaluation of these two features should be a basic premise of upper facial surgery.Methods The authors present a surgical sequence in which endoscopic forehead lifting and lowering of the high hairline by means of a scalp flap advancement are carried out during the same operation. The incision line is located along the hairline. After the scalp and forehead flap are moved, they are fixed using the bone tunnel fixation method.Results In total, 194 patients were treated with endoscopic forehead lifting and simultaneous hairline lowering between August 2018 and July 2020. On average, the patients’ hairlines were 18 mm lower and their eyebrows were 5 mm higher. No patients had serious complications.Conclusions Endoscopic forehead lifting and simultaneous hairline lowering surgery make it possible to address the entire upper third of the face in a single facial rejuvenation operation.

Augmentation mammoplasty with anatomical breast implant, which was first introduced in Korea in February 2012, is expected to increase along with the round implant. This study reports the early experience of a single surgeon with this implant to Korean female patients. A total of one hundred patients who performed augmentation mammoplasty with Replicon ® (POLYTECH Health & Aesthetics, Dieburg, Germany), a kind of anatomical breast implant, from February 2012 to August 2012 were studied. Patient's satisfaction with breast shape and touch was assessed using linear analogue scales with a maximum score of 5. All of the patients received augmentation mammoplasty for cosmetic purpose. Ninety-one patients were satisfied with their results. Neither implant malrotation nor capsular contracture was checked during the average follow up period of 7.9 months. Even though it is a preliminary report of early studies, we can see that anatomical implant is suitable for Korean female patients who have small breast, mild ptotic breast and constricted lower pole, given that anatomical implant proved excellent results in this studies.
