Abstract

Abstract : Abstract: This meta-analysis aimed to provide an up-to-date comparison of donor site morbidity (DSM) between patients who underwent head and neck reconstruction with Anterolateral thigh (ALT) and radial forearm free (RFF) flaps. We searched the PubMed, Web of Science, EMBASE, and Cochrane Library databases to identify studies that compared DSM between ALT and RFF patients. Study quality was assessed using the Newcastle-Ottawa Scale. The pooled odds ratio (OR) of each DSM between ALT and RFF patients was estimated using a random- or fixed-effect model depending on the degree of interstudy heterogeneity. Sensitivity and subgroup analyses were performed if substantial heterogeneity was detected. Eighteen cohort studies with 1, 018 patients (535 ALT and 483 RFF patients) were included. Compared with RFF, ALT were associated with lower risks of wound dehiscence (OR = 0.2, 95%CI: 0.10-0.42, P < 0.01), strength impairment (OR = 0.18, 95%CI: 0.07-0.47, P < 0.01), and movement impairment (OR = 0.19, 95%CI:0.07-0.49, P < 0.01). A subgroup analysis showed that ALT were associated with a lower risk of donor site numbness among patients undergoing tongue reconstruction (OR = 0.05, 95%CI: 0.01-0.25, P < 0.01), but not among all patients undergoing head and neck reconstruction. The pooled ORs of other DSMs demonstrated no significant difference between ALT and RFF patients. ALT are superior to RFF for head and neck reconstruction in terms of donor site wound dehiscence, strength impairment, movement impairment, and for tongue reconstruction specifically in terms of donor site numbness. No significant differences in the incidence of donor site hematoma/seroma, infection, or dissatisfaction with donor site appearance were identified between ALT and RFF patients.
