ADVANTAGES OF USING A SPLIT THICKNESS SKIN GRAFT WITH ADM (ACELLUAR DERMAL MATRIX) FOR DONOR SITE OF SUPRAFASCIAL RADIAL FOREARM FLAP

초록

im: Radial forearm flap (RFF), which is useful for tissue reconstruction, covered with split thickness skin graft (STSG). In case, flexor carpi radialis tendon exposure due to skin graft loss induce increasing period of dressing, rehabilitation, and need more procedure. We performed to harvest with RFF and cover with STSG with ADM simultaneously and try to find the effectiveness and usefulness of our methods. Method: The retrospective study was that underwent RFF from 2006 to 2021. 32 patients were classified to Group A (subfascial dissection) or Group B (suprafascial dissection) according to the flap elevation method. The donor was covered with STSG. And we use the ADM in group B simultaneously, but not use ADM in group A. Data were collected with patient information, size of donor site, healing time, additional procedure, and donor complications. Results / Discussion: Group A was 13 patients of mean age 56.15 years, group B was 19 patients of mean age 59.11 years. In Group A, mean defect of donor was 42.83 cm². In Group B, mean defect of donor was 33.32 cm². There were 13 donor site complications, 8(62%) in Group A and 5(26%) in Group B. Flexor tendon exposure occurred in 3 patients in Group A and none in Group B. mean treatment of donor was 41 days (group A) and 26 days (group B). Delayed healing in 13 patients: 8 patients in group A(62 %) and 5 patients in group B(26 %). Conclusion: Group B has less tendon exposure and shorter treatment period than group A. Suprafascial RFF and cover with STSG using ADM simultaneous is helpful method for donor complication.
