Glabrous skin on the palmar aspect of the hands and the plantar aspect of the feet has special attributes which define the skin on the palm, fingers, and sole as functionally and aesthetically different from skin on other parts of the body. When there is a glabrous skin defect, it should be replaced with similar skin to restore function and aesthetics. The authors reported their 12-year experience with the technique of glabrous dermal grafting for the reconstruction of palmar and plantar skin defects.
From 1992 to 2004, 13 patients with 14 defects underwent glabrous dermal grafting of either palmar or plantar defects, which included 9 hand and 5 foot defects. Etiologies included 9 acute burns, 1 secondary burn reconstruction, 2 delayed reconstructions of traumatic injuries, 1 congenital nevus, and 1 malignant melanoma. Donor sites included 12 glabrous dermal grafts from the foot and 2 from the hand.
Follow-up ranged from 1 month to 65 months. All glabrous dermal grafts demonstrated complete epithelialization and no incidence of complete loss. There was return of sensation without hyperkeratosis or breakdown. The grafts demonstrated good color match with the surrounding skin. The donor sites healed without complications, and there were no incidences of significant hypopigmentation, hyperpigmentation, or hypertrophic scarring.
Glabrous dermal grafting of palmar and plantar defects is the ideal way to reconstruct glalbrous skin to restore both function and aesthetics and to minimize donor-site morbidity.
