Trends in parotidectomy over 30 years in an Australian tertiary care center.
BACKGROUND
Nomenclature, classification, and management of parotid tumors are constantly evolving; this study was performed to identify temporal trends in histology and facial nerve sacrifice in parotidectomy during a 30-year period (1987-2018).


METHODS
Retrospective analysis of patients treated in a single tertiary-care institution during this time period was performed with analysis of temporal trends.


RESULTS
Two thousand eight hundred and fifty-seven parotidectomies were performed; pleomorphic adenoma was the most common histology (34.3%), followed by skin cancer metastases (32.3%). Significant trends noted were increasing age (P < .001), fewer parotidectomies for inflammatory lesions (P < .001), reduced incidence of mucoepidermoid carcinoma (P = .048), increasing incidence of parotidectomy for cutaneous malignancies (P < .001), and reduced facial nerve sacrifice (P = .034).


CONCLUSION
In this contemporary series of parotid pathology, metastatic cutaneous malignancies accounted for a third of cases. Despite reducing facial nerve sacrifice in parotid disease, it is still required in approximately 15% of malignancy and needs to be discussed with all patients preoperatively.
