Effects of heterogeneous acellular dermal matrix implantation on gustatory sweating syndrome in patients with benign parotid tumors
Objective To investigate the effect of heterogeneous acellular dermal matrix (H-ADM) implantation on Frey's syndrome (gustatory sweating) in patients with benign parotid tumors after surgery and to provide a clinical reference for prevention.Methods From March 2018 to December 2021,90 patients who underwent parotid tumor excision were as-signed to control group (44 patients) or study group (46 patients) based on H-ADM implantation.Surgery and postopera-tive recovery,foreign body sensation,complications,Frey's syndrome occurrence,and cosmetic satisfaction were compared between the groups.Results No significant differences were found in intraoperative blood loss,time of operation,time of drainage tube placement,or length of hospital stay between the groups (P>0.05).Incidence of postoperative foreign body sensation,facial paralysis,ear numbness,salivary leakage,infection,and fever were also not significantly different (P>0.05).The study group showed significantly lower subjective and objective positive rates of Frey's syndrome within 12 months after surgery compared to the control group (P<0.05).At 3 and 6 months after surgery,the objective positive rate in the study group was significantly lower (P<0.05),but there was no significant difference at 12 months (P>0.05).Cosmetic satisfaction was significantly higher in the study group than in the control group (P<0.05).Conclusion H-ADM implantation effectively reduces the risk of Frey's syndrome in patients with benign parotid tumors after surgery,elevates cosmetic satisfaction,and does not increase discomfort or the risk of other complications.
