Background For 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. Methods From 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. Results A 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. Conclusions The 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: To avoid the somewhat operated look while effectively resolving shortcomings inherent in the conventional blepharoplasty technique, the authors propose an infrabrow excision blepharoplasty as a satisfying and useful alternative. The authors' experience during a 3-year period is presented and reviewed. Methods: Sixty-four patients were operated on by infrabrow excision blepharoplasty. The indications for the procedure included those patients with one or more of the following criteria: (1) prior infrabrow excision, (2) desire to preserve inborn lid crease lines, (3) multiple prior lid operations related to double-eyelid operation, (4) lateral lid hooding being the primary concern for wanting blepharoplasty, (5) planned or preexisting cosmetic tattoo of the eyebrows, and (6) age group in the late 30s through mid-50s, thus excluding the most severe forms of blepharochalasia. The mean postoperative follow-up period was 13 months, and the photographic results were collected retrospectively and evaluated. Results: There was no complication related to surgery in terms of the resulting scar and periorbital sensory change. The mean operative time was 35 minutes. Significant flattening of the eyebrow or lid crease discrepancy necessitating additional surgery was not observed. Patient satisfaction was very high in terms of both the aesthetic outcome and patient comfort. Conclusion: Infrabrow excision blepharoplasty can be an easy and satisfying alternative that achieves the same goals as a conventional blepharoplasty in a selected group of patients.

Hyaluronic acid filler injection is widely used for soft tissue augmentation. However, there can be disastrous complications by direct vascular embolization. We present a case of ischemic oculomotor nerve palsy and skin necrosis after hyaluronic acid filler injection on glabellar. Blepharoptosis, exotropia and diplopia developed suddenly after the injection, and skin necrosis gradually occurred. Symptoms and signs of oculomotor nerve palsy continuously improved with steroid therapy. Skin defects healed with minimal scars through intensive wound care. Percutaneous filler injection of periorbital areas should be performed carefully by experienced surgeons, and the possibility of embolization should be considered promptly if symptoms develop.
