  • Background: The medial canthal region features a complex three-dimensional and internal anatomical structure. When reconstructing a defect in this area, it is crucial to consider both functional and aesthetic aspects, which presents significant challenges. Generally, local flaps are preferred for reconstruction; however, skin grafts can be used when local flaps are not feasible. Therefore, we conducted a comparative analysis of surgical outcomes skin grafts when local flaps were not feasible, to determine which surgical method is more effective for medial canthal region reconstruction. Methods: Twenty-five patients who underwent medial canthal region reconstruction using skin grafts or local flaps from 2002 to 2021 were enrolled. Patient information was obtained from medical records. Five plastic surgeons evaluated the surgical outcomes based on general appearance, color, contour, and symmetry. Results: Skin grafts were used in eight patients and local flaps were used in 13. Combined reconstructions were employed in four cases. Minor complications arose in four cases but improved with conservative treatment. No major complications were reported. Recurrence of the skin cancer was noted in two cases. All categories showed higher scores for the local flap compared to both skin graft and combined reconstruction; however, the differences were not statistically significant respectively. Conclusion: The choice of appropriate surgical methods for reconstructing defects in the medial canthal region depends on various factors, including the patient's overall health, the size and depth of the defect, and the degree of involvement of surrounding structures. When a local flap is not feasible, a skin graft may provide favorable surgical outcomes. Therefore, a skin graft can serve as a viable alternative for reconstructing the medial canthal region.

  • Background A tie-over dressing is the accepted method to secure skin grafts in order to prevent haematoma or seroma formation. We describe the novel application of a barbed suture tie-over for skin graft dressing. The barbs act as anchors in the skin so constant tensioning of the suture is not required. Methods From January 2014 to August 2014 we used the technique in 30 patients with skin defects requiring split-thickness or full-thickness grafts. Patient demographics, clinicopathological details and graft outcome were collected prospectively. Results The majority of cases were carried out for split-thickness skin grafts (n=19) used on the lower limb (n=20). The results of this novel technique were excellent with complete (100%) graft take in all patients. Conclusions Our results demonstrate the clinical application of a barbed device for securing skin grafts with excellent results. We find the technique quick to perform and the barbed device easy to handle, which can be applied without the need for an assistant.

  • The objective of this study was to observe the healing of skin and mucosal grafts, comparing with the control sites. Six adult dogs were divided into two groups of three. Mucosal defects were created in all four quadrants, and the left side was used as a control. In the Group I animals, a split-thickness skin from the chest was grafted, and in the group II animals, a split-thickness mucosa from the buccal cheek was grafted into the mouth. Gross and microscopic examination was done at 3, 7, 14, 28, 42 days. The results were as follows. 1. Wound epithelization was accelerated in the supraperiosteal grafts. 2. After healing, the grafted skin was unnatural to the oral cavity, showing grayish-white color, hair, and sebaceous gland. But the mucosal grafts could not be discriminated from the adjacent mucosa. 3. the grafting on the cortical bone failed.

  • Purpose: Split-or full-thickness skin grafts are used to reconstruct palmar skin and soft tissue defects after trauma or to release burn scar contracture on the hand. Glabrous skin defects should be substituted with similar skin to preserve function and aesthetics. The authors report their experiences with a technique that uses a full-thickness graft taken from glabrous skin on the ulnar edge of the palm for the reconstruction of soft tissue defects of the hand. Methods: During a three-year period from 2007 to 2010, 22 patients with burn scar contracture and 12 patients with post-traumatic skin defects on their hands were treated with full-thickness skin graft operations. The palmar skin and soft tissue defects after release of burn scar contracture or debridement of post-traumatic wounds were reconstructed with full-thickness skin grafts harvested from the ulnar border of their palms. All donor-site wounds were primarily closed. Results: The followup periods ranged from 3 to 25 months. Contractures of the hand were corrected without recurrence, and the grafts showed relatively good contour and color match to the adjacent fields. There were no reported complications such as significant color change or hypertrophic scarring. The grafted skin showed an average 5.9 mm static two-point discrimination obtained in fingertip reconstruction cases, indicating satisfactory reinnervation. Conclusion: Glabrous full-thickness grafts harvested from the palmar ulnar border is a very useful way of reconstructing soft tissue defects on hands, including fingertips, for function restoration, favorable aesthetic results, and low donor-site morbidity.

  • There are many different approaches to healing of acute and chronic ulcer and large skin defect, such as burn. Currently available wound covers fall into two categories. Permanent covering, such as autografts, and temporary ones, such as allograft including de-epidermized cadaver skin, bioartificial skin, xenografts, and synthetic dressings. Autologous skin grafting in the form of split- or full-thickness skin is still the good standard. Following on from developments in the 1980s involving the use of cultured keratinocyte grafts in wound healing, the last decade has been great progress in the fabrication of composite bioartificial skin grafts. However, two bottleneck on producing cultured bioartificial skin, whether of the simple epithelial cell sheet type, or the more complex composite type, continue to be the generation of sufficient keratinocytes cheaply and quickly and develop biocompatible dermal scaffolds. This article covers the development, clinical application, and current research directions associated with bioartificial skin.

  • 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)$g/hr/m^2$, 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.

  • In order to test the effects of hyperbaric oxygen (HBO) and $\alpha$-tocopherol on full-thickness skin grafts in rats, we peeformed full-thickness skin grafts bilaterally on rats. After surgery, we analyzed the tissue-concentrations of superoxide dismutase (SOD), catalase, and glutathione peroxidase(GPx)/reductase(GPr) on days 0, 2, 4, 7, 10, 14, 21 and 28. The four groups had similar patterns of change in SOD, catalase, GPx and GPr values. SOD increased initially, and was significantly increased at day 7, returning to the preoperative activity level on day 14 (control, HBO, and $\alpha$-tocopherol treated alone) and 28 (HBO plus $\alpha$-tocopherol). Catalase had a similar pattern of change as the SOD enzyme activity, except for the surgical control on day 2. Glutathione peroxidase/reductase activity in the four groups had a similar pat-tern of enzyme activity, with a significant increase from preoperative level on day 4, peaking during days 7 to 10, and returning to preoperative level on day 21(surgical control, HBO, and $\alpha$-tocopherol-treated alone) and 28 (HBO plus $\alpha$-tocopherol treated group). Hence, the clinical use of HBO and $\alpha$-tocopherol mixture can be recommended as an adjunctive treatment for free skin grafts in rats. But, the antioxidant used, its dose, and the timing of its administration, as well as, the exposure time and the pressure of HBO, should be the subject of further research.

  • Background The scalp, an excellent donor site for thin skin grafts, presents a limited surface but is rich in stem cells. The purpose of this study was to test a double harvesting procedure from the scalp and to evaluate the capacity of the dermal layer. Methods Two layers corresponding to a split-thickness skin graft (SSG) and a split-thickness dermal graft (SDG) were harvested from the scalp using a Zimmer dermatome during the same procedure. Healing of the scalp donor site, reason for recipient site grafting, and the percentage of graft loss were evaluated. Results Fourteen patients, comprising six men and eight women with a mean age of 34.2 years, were treated according to our protocol. The most common reason for a recipient site graft was a postburn scar deformity (10/14 patients). The mean area of scalp SSGs was 151.8 cm2. The mean area of scalp SDGs was 88.2 cm2. The mean healing time of scalp donors was 9.9 days. The only donor complication was a tufted scar deformity. Conclusions Skin defects in the scalp of donors healed faster and led to less scarring than defects at other donor sites. Scalp SDGs needed 10 days for adequate epithelization. The scalp was the best donor site for SSGs and SDGs for burn reconstructive patients.

  • Amniotic fluid is a complex and biological reservoir that provides mechanical cushioning and has many nutrients required for fetal growth and development. During our main research works about the fetal surgery of congenital facial defects, we reviewed several recent articles about the effectiveness and composition of amniotic fluid. Among these review processes, amniotic fluid, as the convenient medium to store sking grafts, was focused especially for its growth factors and rich nutrients, and we summarized some experimental investigations of skin grafts stored in amniotic fluid in rats. We reviewed mainly the article, "Turhan-haktanir N. et al. Histological assessment of skin grafts in amniotic fluid and saline. J Plast Surg Hand Surg 2010;44:226-30."

  • Performing a skin graft is not feasible for tendon-exposed defect reconstruction because tendons are fibrous connective tissues with relatively poor blood supply. This study proposes a method to effectively perform skin graft surgery in tendon-exposed wounds. A 48-year-old male patient with diabetes mellitus had a very large left dorsal foot defect (8×8 cm). The wound bed had healthy granular tissue, with tendon exposure. The tendons were turned over so that the posterior side would behave as the anterior side. The edge of the paratenon was then fixed together to the surrounding granulation tissue or dense remnant fascia using absorbable sutures, and the close granulation tissue was approximated and buried. A split-thickness skin graft was performed after 1 week. The graft site was stably taken on postoperative day 3. A small disruption was then observed at the graft site within 1 week postoperatively, but conservative treatment was continued for 1 month, after which the defect site was completely restored. This technique can increase the success rate of skin grafts for defects with tendon exposure.
