Abstract
OBJECTIVE
The aim of this study was to evaluate the efficacy of acellular dermal matrix (ADM) use in reducing Frey syndrome (FS) rates in patients postparotidectomy.
STUDY DESIGN
We performed a systematic review and meta-analysis of existing literature comparing rates of FS with and without ADM use.
RESULTS
Eight studies were shortlisted for qualitative study, of which 7 compared rates of FS with and without the use of ADM. A total of 211 patients underwent parotidectomy with the use of ADM. Of these, mean patient age was 44.7 (SD ± 7.2); 89 of 159 were pleomorphic adenoma (55.9%), 29 of 159 with histological diagoses stated were Warthin's tumor (18.2%), and 159 of 211 were other histologic diagnoses (25.7%). Subjective and objective incidence rates for FS were 23 of 211 (10.9%) and 7 of 211 (3.3%), respectively. Patients in whom ADM barriers were used had significantly lower rates of subjective and objective FS (relative risk = 0.22; 95% confidence interval, 0.09-0.57; P = .002; and relative risk = 0.07; 95% confidence interval, 0.07-0.33; P < .001), respectively, compared to patients with no ADM.
CONCLUSION
The use of ADM was associated with lower FS rates compared to no ADM and should be considered in routine use to prevent this condition.
