[Repeated recurrences after operations of non-malignant parotid tumours (author's transl)].

Recurrences of 222 operated on parotid tumours (1961--1975) are analysed. Recurrences and repeated recurrences of benigh parotid tumours are based on not corresponded praeoperations (without nerve preparation). The half of cases of first-recurrences (mixed tumours) will become further recurrences. In repeated parotid-recurrences should be done total parotidectomy with careful treatment of facial nerve.
