Second-Layer Palmar Graft for Fingertip Reconstruction: An Analysis of Aesthetic and Functional Outcomes

Fingertip injuries are very common and require a stable and durable cover. The end result after reconstruction must be a painless finger with good aesthetic appearance. Skin loss in fingertip, with or without partial loss of pulp fat, is often managed with a split-thickness skin graft, which causes a poor aesthetic result due to color mismatch of the grafted skin in the glabrous volar skin of fingertip. The full-thickness and partial-thickness skin graft harvested from palmar skin provide color match but may cause donor site morbidity in the form of painful scar or contour deformity. Harvest of the second layer from the palm (intermediate part of dermis) allowed the first layer (epidermis with superficial part of dermis) to be reposed over the remaining dermis in palm, thus allowing closure of donor defect without any tension. This technique provides a good color match for the primary defect, along with reduced donor site morbidity.

The study aims to analyze the outcomes of second-layer palmar graft (SLPG) in patients with fingertip injuries.

The retrospective study was conducted in January 2012 on 40 patients who underwent SLPG.

The graft take was 100% in 36 patients with an average static two-point discrimination (2PD) of 6 mm. The average cosmetic visual analog score for the donor area was 100 and recipient site was 80.

The SLPG is a good surgical procedure for reconstructing fingertip defects, providing excellent aesthetic appearance and optimal function.
