OBJECTIVE: Knowledge about parotoidectomy indications is based on notifications to ENT departments and tumor databases. The study investigates the hypothesis that the surgical indication for parotoidectomy has changed over recent years.
MATERIAL AND METHODS: We performed a retrospective observation study of patients who underwent parotidectomy between 1975 and 2016 (subdivided into 4 quartiles) in a teaching hospital of a medical university.
RESULTS: 405 men and 366 women underwent operation for benign tumors (600/78 %), malignant tumors (116/15 %) or parotitis (55/7 %). The proportion of benign tumors remained unchanged (78 %), whereas malignant tumors increased (7 % - 23 %) and parotitides decreased (17 % - < 1 %). In benign tumors, the proportion of pleomorphic adenomas decreased (60 % - 24 %), whereas Warthin tumors increased (23 % - 58 %). Among malignant tumors, the proportion of metastases increased from 2/13 to 31/49 (in particular squamous cell carcinomas of the skin).
CONCLUSIONS: The present the study shows the decreasing importance of parotitis as an indication for parotidectomy due to improved non-surgical procedures. The increasing prevalence of Warthin tumors was associated with an increasing proportion of smokers. Increased number of malignant tumors was caused by an increased prevalence of intraparotidial matastases of cutaneous squamous cell carcinoma. The presented results are based on the evaluation of patient charts. Due to their ICD or DRG reference, histological findings cannot be generated by evaluating databases. For this purpose, a special salivary gland tumor database should be established.
