Frey's syndrome was first described in the 18th century. Recognizing it as a nonspecific condition, the symptom of gustatory sweating in patients with parotid gland inflammation was described by Duphenix and Baillarger. However, as a specific diagnostic entity, gustatory sweating, following trauma to parotid glands, was first described by Polish neurologist Lucie Frey, in 1923, and hence he proposed the term auriculotemporal syndrome. The condition is characterized by sweating, flushing, a sense of warmth, and occasional pain in the preauricular and temporal areas, following the production of a strong salivary stimulus. Several etiologies of Frey's syndrome have been mentioned in the literature; however, none attribute dislocation of the “intact” mandibular condyle as a cause of the syndrome. Reviewing its pathophysiology, etiology, and incidence in detail, we describe a case of Frey's syndrome subsequent to superolateral dislocation of the intact mandibular condyle following fracture of the anterior mandible. Its management and prevention are also discussed in brief.

Background: Frey’s syndrome is a well-known complication of parotid surgery; its prevention may be achieved by the use of an interpositional barrier between the overlying flaps and the exposed parenchymal bed of parotid gland. The aim of this study was to retrospectively evaluate clinical outcomes with and without the interpositional placement of a porcine dermal collagen graft (PDCG) for prevention of syndrome occurrence. Methods: We conducted a 20-year retrospective study including the patients who had undergone “formal” (superficial, total, or subtotal) parotidectomies for benign pathologies. The inclusion criteria also involved patients that were (i) regularly monitored about clinical symptoms related to syndrome, and (ii) examined with Minor starch-iodine test. The severity of the diagnosed syndrome was retrospectively evaluated according to the grading score system of Luna-Ortiz. To assess group differences in terms of the extent of dissection in operating sites, we estimated the tumor and histological specimen volumes using the available dimensions. Results: We included 73 patients who had undergone 76 formal parotid surgeries. The surgical sites were divided into 2 groups: (1) Group A consisted of 44 sites that were reconstructed with a SMAS flap, and (2) Group B, comprised 32 sites where a PDCG was additionally applied as an artificial preventive barrier. At a mean follow-up of 26.3 months, a significantly lower incidence of clinically diagnosed Frey’s syndrome was found after the use of dermal collagen interpositional barrier ( P = .031). Specifically, subjective symptoms were reported at an incidence of 31.8% in Group A and 6.7% in Group B. Minor’s test was positive at an incidence of 59.09% in Group A and 21.87% in Group B ( P = .004, 95% CI). Severe Frey’s syndrome was observed in 31.82% of the patients of Group A and in 3.12% of the patients of Group B ( P = .002, 95% CI). Since there were no statistical significant differences between the volumes of the removed tumors and the excised histological specimens, the extent of dissection was not proved to influence the occurrence of Frey’s syndrome in the compared groups, Conclusion: Porcine dermal collagen is a safe, practical, and useful means for parotid reconstruction, since it seems to contribute in prevention of Frey’s syndrome when increased amount of glandular tissue has to be removed. Additional randomized controlled studies with bigger samples are required to better assess the PDCG use in parotid surgery.

Aberrant Regeneration

Frey's syndrome was first described by Lucia Frey, a Polish neurologist in 1923. It is well accepted that it involves injury to the branches of the auriculotemporal nerve with subsequent aberrant regeneration. Due to this abnormal communication, the skin glands and vessels are always stimulated at the same time as eating and mastication, which results in symptoms such as flushing and sweating. The incidence of Frey's syndrome in the literature has been variously described from 6 to 96 per cent. We analyzed the chart of 18 patients who had parotidectomy from March 2002 to December 2009. All procedures were performed by a single surgeon at the same facility. A total of 16 superficial and three total parotidectomies were done; one patient had bilateral parotidectomy. Oxidized regenerated cellulose (Interceed) was used after 10 surgeries (study group) and no adjuvant was used after nine surgeries (control group). All of the surgeries were done using similar technique. All the patients were followed-up with for a period of about 6 months postoperatively. The absolute risk reduction associated with the placement of an Interceed was 11 per cent. The small number of cases (n = 19) and an empty cell limits statistical analysis (a Fisher's exact test revealed a P value of 0.44). Clearly the low number of procedures restricted the power to test these differences. The development of Frey's syndrome is a very disabling but under-reported complication. The placement of a temporary barrier like Interceed may help in the prevention of Frey's syndrome without increasing any complications.
