Comparison of Flaps From Different Sites for Repairing Postoperative Soft Tissue Defects Regarding the Quality of Life in Patients With Oral Cancer: A Systematic Review.

This study aims to compare flaps at different sites in treating soft tissue defects after oral cancer surgery and improving patients' quality of life (QoL). Databases were searched until September 2023. The extracted data included the scores of chewing, swallowing, speech, mood, and appearance based on the University of Washington QoL questionnaire, version 4. Two types of free flaps and 2 types of pedicled tissue flaps were included. The free flaps were the forearm free flap (FFF) and anterolateral thigh flap, and the pedicled tissue flaps were the submental artery island flap and pectoralis major myocutaneous flap (PMMF). Compared with FFF, there was no significant difference in the scores of chewing, swallowing, speech, and mood among anterolateral thigh, submental artery island flap, and PMMF, and PMMF generally had a higher score than FFF only in terms of appearance, with statistical significance. There is no significant difference in chewing, swallowing, speech, and mood between flaps from different sites in repairing postoperative soft tissue defects of oral cancer. Therefore, the widely used FFF may be the preferred choice considering the QoL of patients after oral cancer surgery.
