Background: Donor site morbidity is a significant drawback of the radial forearm flap. The purpose of this study is to describe a new shape-modified technique. The donor site morbidity was compared to that of the conventional technique, in terms of the esthetic, functional outcomes, and quality of life (QOL). Methods: This is a prospective study of 30 patients with oral cancer who underwent reconstruction using radial forearm flaps, in two groups. Results: Regarding the donor site characteristics, the differences in the time for healing (P = .006), the scar score (P < .0001), and the QOL score (P < .0001) were significant. The number of patients with sensory deficit was 11 in the conventional group and 3 in the shape-modified group (P = .009). Conclusions: The functional and esthetic outcomes of the donor site were better for the shape-modified technique. It is best suited for small defects. Compromise of the pedicle length is a limitation.
