Abstract

OBJECTIVE:

To evaluate the effectiveness of AlloDerm, an acellular human dermal matrix graft, as an interpositional physical barrier to prevent the development of Frey syndrome after parotidectomy.

METHODS:

The 30 patients included in the study were divided into 3 groups of 10. In group 1 (study group), patients underwent superficial parotidectomy with placement of an AlloDerm graft (LifeCell Corp, Branchburg, NJ). In group 2 (control) patients had superficial parotidectomy without placement of an interpositional barrier. In group 3 (control), patients underwent deep-plane rhytidectomy without disruption of the parotid fascia. All were evaluated after 1 year and questioned about gustatory sweating. Subjective assessment of Frey syndrome was documented when patients experienced gustatory sweating, even if they were not perturbed by the symptom. The Minor starch-iodine test was performed in each patient for objective assessment.

RESULTS:

The incidence of subjective Frey syndrome was observed in 1 patient in group 1 and 5 patients in group 2. The incidence of objective Frey syndrome was noted in 2 patients in group 1 and 8 patients in group 2. Both subjective and objective differences in incidence of Frey syndrome were statistically significant. None of the group 3 patients had subjective or objective Frey syndrome. Two patients in group 1 and 3 patients in group 2 developed a transient seroma or sialocele that resolved with conservative management.

CONCLUSION:

The use of AlloDerm graft as an interpositional barrier improves parotidectomy outcome by reducing the incidence of Frey syndrome.
