Abstract :

Purpose: Comparison of Frey syndrome rates following superficial parotidectomy (SP group) and partial superficial parotidectomy (PSP group) by using porcine dermal collagen graft. Methods: 250 patients presented with a benign parotid tumor at the department of oral and maxillofacial surgery of Zhengzhou University of China between January 2018 to December 2019 were included in the study. 125 patients underwent superficial parotidectomy and 125 underwent superficial partial parotidectomy Porcin Dermal Collage graft was used in surgery. The patients who underwent superficial parotidectomy were compared to those who underwent partial superficial parotidectomy in terms of Frey syndrome development and recurrence at 6 months. Results: The SSP group included 125 patients (51 women and 74 men) with a mean age of 48.4�9.6 years; the PSP group included 125 patients (77 women and 48 men) with a mean age of 50.2�11.2 years. Most common tumor observed was pleomorphic adenoma followed by Warthin�s tumour, Basal cell carcinoma, myoepithelioma and cystadenoma in both the group. Frey syndrome was seen in 3 (2.4%) patients in PSP group and in 9 (7.4%) patients in SP group. Immediately facial paralysis was significantly more common in SP group (19.2%) then PSP group (4.0%). Conclusion: Compared to the SP group, the PSP group had shorter operative durations and fewer postoperative complications. Therefore, PSP should be considered in suitable cases. Permacol produced good results in both postoperative facial contouring and prevention of Frey�s syndrome.
