Abstract

Abstract: Objective: To evaluate the applicable effect of forearm dermal fat flap in the repair of defects in oral and maxillofacial region. Methods: From July 2020 to June 2023, 24 patients with soft tissue defects in oral and maxillofacial region were repaired with forearm flap. According to the method of operation criteria, 24 patients were divided into traditional forearm flap group (12 cases) and forearm dermal fat flap group (12 cases). The flap preparation time, flap size, and the appearance and function of the forearm donor site at 6 months post-operatively were evaluated. Results: The flap survival rates of both groups were 100%. The flap preparation time of traditional forearm flap group was shorter than that of the forearm dermal fat flap group (P<0.05), and there was no difference in the flap size between two groups (P>0.05). Six months after the surgery, there was significant difference in the pigment deposition and surgical scars in the donor area between two groups (P<0.05), however, no significant difference in hand sensation and wrist movement (P>0.05). Conclusion: There was no difference in the functional recovery of the donor site between two groups of patients. The forearm dermal fat flap avoided the third surgical site and had little impact on the appearance of the donor site, which provided an alternative to the conventional forearm flap harvest.
