“…14,[19][20][21] In contrast, Koch et al and Santos et al demonstrated that the frequency of complications (including Frey syndrome) decreased when a smaller amount of glandular tissue was removed in a parotidectomy. 3,24 In agreement with these authors, the present work found an increased risk for the development of Frey syndrome in the lumpectomy AP, superficial, and total parotidectomy groups compared with the risk associated with lumpectomy T; however, no differences were found in the symptom-free rates associated with superficial and total parotidectomies. Perhaps the low number of patients who underwent a total parotidectomy in this study contributed to a skewed result.…”

“…Since FS develops due to the aberrant re-innervation between the residual deep parotid tissue and skin sweat glands, the avoidance of the attachment of these two structures is the main aim in the prevention of FS (21). The pathophysiology of FS was first defined as autonomic re-innervation between the skin and parotid gland by Lucja Frey in the early twentieth century (22,23). In fact, it is thought that FS is the result of the cross-innervation between post-ganglionic secretomotor parasympathetic nerve fibers of the parotid gland and post-ganglionic sympathetic system branches of the skin's sweat glands (8).…”

Objective: To investigate the outcomes of superficial musculoaponeurotic system (SMAS) flap and classic techniques in superficial parotidectomy in terms of Frey's syndrome (FS) and cosmetic satisfaction. Methods:In this study, a retrospective chart review of patients that underwent superficial parotidectomy was performed. These patients were divided into two subgroups: group 1 included patients in which the SMAS flap was harvested and group 2 comprised the remaining patients on whom classic superficial parotidectomy was performed. All the patients were evaluated clinically and with Minor's starch-iodine test for FS. For the evaluation of the cosmetic results, the patient's satisfaction was queried according to the incision scar and surgical field skin retraction/facial symmetry. Both groups were compared in terms of complications and numbness of surgical area.Results: Fifty-five patients (31 male and 24 female) with a mean age of 50.19 years were included in the study. Thirty-two patients were in group 1 and 23 in group 2. Thirteen patients (23.7%) described as having FS and six of them were in group 1, while seven were in group 2. Minor's starch-iodine test was positive in nine patients in group 1 (28.1%) and six patients in group 2 (26.1%) (p=1.000). With regard to cosmetic satisfaction, eight patients (25%) stated mild discomfort from the incision scar and two patients (6.3%) stated cosmetic dissatisfaction for facial asymmetry in group 1. In group 2 for the same factors the number of patients were 11 (47.8%) and 2 two (8.7%), respectively (p=0.027). There were no statistically significant differences in means of complication and numbness (p>0.05). Conclusion:According to our study results, there was no superiority between both the groups in terms of FS and incision scar satisfaction. We determined that there was a significant benefit of SMAS flap application in the prevention of volume loss and surgical area retraction.

“…The classic syndrome triad is hyperemia, heat and sweating in the pre-mandibular region and the mandible angle area [24]. The most widely accepted explanation for Frey's syndrome is the transection of postganglionic parasympathetic secretomotor fibres from the otic ganglion originally directed to the parotid gland, followed by aberrant re-innervation of the denervated facial cholinergic sweat glands and blood vessels.…”
