Oh, Kim, Choi, and Lee: Thin Split-Thickness Toe Nail-Bed Grafts for Nail Bed Defects in Subungal Exostosis: Two Cases Report

Abstract

We reviewed the clinical features of 2 patients who underwent surgery for subungal exostosis, focusing on postoperative deformity of the nail. The lesion destroyed the nail bed and was excised with a direct approach. then thin split-thickness sterile matrix graft was done after excision of the tumor because the defect of the nail bed was large. Good postoperative appearance of the nail was obtained by thin split-thickness sterile matrix graft. The use of thin split-thickness sterile matrix graft for the replacement of a nail bed defect can regain a smooth, adherent, and normal-looking nail and avoid donor-site morbidity. Thin split-thickness toe-nail bed graft is a good choice for the prevention of postoperative deformity.

Figures and Tables

Figure 1
A 14 year old male patient had subungal exostosis of great toe with ulceration of medial border of the nail and elevation the nail plate.

Figure 2
Preoperative radiograph showed a bony excrescence arising from the distal phalanx.

Figure 3
The tumor was approached directly from its top (After excision of the tumor).

Figure 4
Thin split-thickness nail bed graft was done to the defect. The black arrows show donor site and the yellow arrow shows recipient site.
