- Abstract: Objective To compare the efficacies of acellular dermal matrix(ADM)and pedicle buccal fat pad flap(PBFPF)in repairing buccal soft tissue defect.Methods A total of 84 patients undergoing repair of buccal mucosa defect in our hospital were selected and randomly divided into the ADM group and PBFPF group,with 42 cases in each group.Patients of the ADM group were repaired tby ADM,while patients of the the PBFPF group were repaired by PBFPF.The repair time,oral feeding time,hospital stay were compared between the two groups.The maximum opening degree of patients before surgery,and 1 week,1 month and 6 months after surgery was measured and compared.The effective rate of repair and the occurrence of complications of patients were recorded.The improvement of oral and maxillofa-cial function(including swallowing function,language function and masticatory function)after surgery of patients were observed.Results There was no significant difference in the repair time,oral feeding time,hospital stay,total incidence of complications,postoperative swallowing function or postoperative language function between the two groups(P＞0.05).The maximum opening degree had no significant difference between the ADM group and PBFPF group or in the interaction effect between groups and time points(P＞0.05),but had signifi-cant difference in the comparison of time points(P＜0.05).The effective rate of repair for patients with defect area of＞13～20 cm2 in the PBFPF group was higher than that in the ADM group(P＜0.05).The masticatory function of patients in the PBFPF group was better than that in the ADM group(P＜0.05).Conclusion Both PBFPF and ADM have advantages in the repair of oral mucosal tissue defects,and PBFPF has better repair effect in patients with larger mucosal defect area(＞13～20 cm2).
