Abstract:

Objective〓〖WTBZ〗To evaluate the effect of acellular dermal matrix in preventing development of Frey syndrome after parotidectomy. 〖WTHZ〗Methods〓〖WTBZ〗156 patients were divided into 2 groups: the experimental group subjected to superficial parotidectomy with placement of an acellular dermal matrix and the control group subjected to superficial parotidectomy without placement of an acellular dermal matrix. All were evaluated 12 to 37 months later and questioned about gustatory sweating. The Minor starch-iodine test was performed on for an objective assessment. 〖WTHZ〗Results〓〖WTBZ〗Subjective Frey syndrome was found in 4 patients in the experimental group and 32 in the control group. And objective Frey syndrome was found in 7 patients in the experimental group and 46 in the control group. Both subjective and objective differences in Frey syndrome were statistically significant. 〖WTHZ〗Conclusion〓〖WTBZ〗An acellular dermal matrix can reduce the incidence of Frey syndrome, and it is safe and has no side effects.
