Factors influencing Frey syndrome after parotidectomy with acellular dermal matrix

ARTICLE HIGHLIGHTS

Research background

Frey syndrome, also known as ototemporal nerve syndrome or guest-sweating syndrome, is one of the most common complications of parotid gland surgery. It is characterized by abnormal facial skin sensations, flushing, or sweating when the patient thinks, sees, or eats.

Research motivation

This inclusion has inadvertently increased the recorded incidence of Frey syndrome. This retrospective study investigated the factors influencing the acellular dermal matrix (ADM) in the prevention of Frey syndrome in patients who have undergone parotid surgery.

Research objectives

Because of the effects of frey syndrome, there was a need to find a way to reduce its incidence

Research methods

The data of 82 patients were retrospectively analyzed using SPSS 25.0, and the correlations between sex, age, resection sample size, operation time, operation mode, ADM use, and postoperative Frey syndrome were analyzed.

Research results

The incidence of Frey syndrome was 56.1% among the 82 patients. There were no significant differences in sex, age, or operation time between the two groups (P > 0.05). There was a significant difference between ADM implantation and the onset of symptoms of Frey syndrome (P < 0.05). ADM can reduce the variation in Frey syndrome onset. ADM can delay the onset of Frey signs.

Research conclusions

the application of ADM affects Frey syndrome prevention. However, it is important to note that ADM degrades within approximately six months, and Frey syndrome may still occur after this degradation. Additionally, controlling the diameter of the excised samples can help prevent the occurrence of Frey syndrome.

Research perspectives

The incidence of Frey syndrome was reduced by surgery and the implantation of ADM.
