Use of the artificial dermis for free radial forearm flap donor site

The radial forearm free flap has been popular in many area of reconstructive surgery. Despite the many attributes of this flap in surgical reconstruction, one of the clear disadvantages has been the morbidity of the donor site. To solve problems associated with closure of the radial forearm flap donor site, the artificial dermis was used for better outcome in the donor site. From July of 2001 to October 2003, 13 patients (12 male, 1 female) ranging in age from 27 to 67 years underwent free radial forearm transfers. Flap size measured 49 to 144 cm2. Donor-site defects secondary to the flap elevation was closed first with the artificial dermis (Terudermis), marketed by Terumo Inc, Japan, and secondary split-thickness skin graft to the artificial dermis was performed in 15 days (range, 13 to 17 days) on average. There was no flap failure in all cases. Partial loss of the artificial dermis graft was noticed in 2 cases, but it was negligible. Secondary skin graft take was noticed in about 7 days, and there was no remarkable skin graft loss. The artificial dermis was used successfully in 13 patients with the donor defects of free radial forearm flap. Despite the disadvantage to need the secondary split-thickness skin graft, use of the artificial dermis gave us not only soft-tissue augmentation and graft-skin quality similar to full-thickness skin graft but also fast graft healing and diminished morbidity of the skin-graft donor site.
