“…The absence of significant differences in the statistical analysis of surgical outcomes between the two methods supports this assertion, suggesting that it could serve as a basis for a more proactive selection of skin grafts in medial canthal region reconstruction. However, minimizing complications through proper donor site selection, correct surgical techniques, and diligent postoperative care is crucial [ 12 , 13 ].…”

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.

Using the skin of the lateral malleolus region for reconstruction of smaller areas of the palm may yield better outcomes than using the skin of the groin region. However, no previous study has provided long-term data comparing the groin and lateral malleolus regions as donor sites for full-thickness skin grafts (FTSGs) in palmar reconstruction. Therefore, this study aimed to compare the groin and lateral malleolus regions as donor sites for FTSGs in palmar reconstruction over a long-term follow-up period. The patients were classified into groin and lateral malleolus region groups (n = 15 each). Measurements were obtained at the graft site, the contralateral site corresponding to the graft site, and the donor site. A chromameter was used to measure skin color, and the Patient and Observer Scar Assessment Scale (POSAS) was used to evaluate the scar at the skin graft site. Compared to the groin region group, the lateral malleolus region group showed skin colors that were closer to the original color of the palm in terms of lightness and red/green values. Additionally, the lateral malleolus region group received better esthetic ratings in the POSAS. Our results revealed that using the lateral malleolus region for FTSGs in palmar reconstruction resulted in better outcomes than using the groin region, even over a long period.

Background: Wound healing is a complex process influenced by a variety of environmental factors. Dressing materials play a critical role in creating barriers against contaminants, maintaining optimal moisture levels, and absorbing wound exudate. Therefore, selecting materials tailored to wound characteristics is crucial for enhancing outcomes. Hyaluronic acid (HA) is a natural biocompatible polymer that supports healing by regulating inflammation and promoting tissue repair. This study compared HA- and hydrocolloid-based hydrogels in a rat model to optimize wound care strategies.Methods: Full-thickness dermal wounds (diameter, 8 mm) were created on the dorsal skin of 12 Sprague-Dawley rats under sevoflurane anesthesia. The wounds were treated with HA/silver sulfadiazine gel (group A), hydrocolloid gel (group B), or left untreated (control), all covered with a transparent dressing. Biopsy specimens on days 3, 7, and 21 were used to assess histological parameters: inflammatory cell infiltration, fibroblast infiltration, collagen deposition, neovascularization, and epithelial thickness, using a semi-quantitative scoring system. Histological analyses were conducted blindly, and statistical analyses were performed using the Kruskal-Wallis test (<i>p</i>< 0.05).Results: On day 3, group A showed significantly higher inflammatory cell infiltration and collagen deposition than other groups, indicating extracellular matrix formation. By day 7, angiogenesis was highest in group A, followed by group B and controls. By day 21, all wounds had completely healed. Epithelial layer thickness, reflecting inflammation and fibroblast maturity, was significantly higher in group A.Conclusion: This study compared HA-based hydrogel and hydrocolloid-based dressings through histological analyses to elucidate wound healing mechanics. HA-based hydrogel dressings significantly enhanced wound recovery. However, generalizing these outcomes requires future studies to expand the range of effective wound treatment materials. These findings underscore the potential of HA-based dressings to enhance clinical outcomes in wound management, suggesting avenues for improving therapeutic strategies.
