Abstract:

BACKGROUND: Recently, great achievements of acellular dermal matrix which is used to prevent Frey syndrome have been reported.
OBJECTIVE: To evaluate the role of oral tissue patch (HEAL-ALL) in preventing Frey syndrome after parotidectomy.
METHODS: Eighty-four patients were divided into two groups. Thirty-five patients of groupⅠwho received a superficial lobe parotidectomy and oral tissue patches were put between the fascia parotidea masseterica flap and the remaining parotid tissue. Group 2 consisted of 49 patients who underwent the parotidectomy. All patients were evaluated for gustatory sweating by identical phone. Sixty randomly chosen patients (group Ⅰ30, group Ⅱ30) were evaluated using the Minor Starch Iodine Test (MSIT).
RESULTS AND CONCLUSION: The responses to phone showed presence of Frey syndrome in 1 of 30 in groupⅠ, whereas group Ⅱ showed 27 of 49 patients presented with Frey syndrome. The objective results test by those who underwent the MSIT revealed a 6.67% (2) and 73.33% (22) incidence of Frey syndrome in groupsⅠ and Ⅱ, respectively. There was significant difference between the two groups (P < 0.01). HEAL-ALL tissue patch is shown to be an effective way for preventing Frey syndrome post-parotidectomy.
