Objectives Pleomorphic adenoma ( PA ) is reported to be the most common benign parotid tumour followed by Warthin tumour ( WT ), but the proportion of these two entities might have changed. Design Retrospective file analysis. Setting Tertiary referral head and neck centre. Participants Patients who underwent a parotidectomy within a period of 25 years (1990–2014). Main outcome measures Rate of occurrence of PA and WT as well as the development of the PA / WT ratio over the years. Results Overall, 1818 patients with WT (707, 38.9%) and PA (1111, 61.1%) were identified. There was a dominance of PA over WT in all years. An increase in percentage of WT , from 24% in 1990 to 48% in 2014, in comparison with PA was evident. Conclusions In our single‐institution hospital‐based material of parotidectomies, the percentage of WT in comparison with PA has significantly increased over the last 25 years.
