RECURRENT BENIGN PAROTID TUMOURS: THE LESSON NOT LEARNT YET?

Abstract

Recurrent benign parotid tumours are uncommon if superficial parotidectomy (SP) is the performed initially; recurrence rates are between 0-4%. The recurrences are usually slow growing and require lengthy follow-up. Pre-operative diagnosis of a lump in the region of previous excision is useful in treatment planning. Malignant transformation in previous benign lump should be considered and fine needle aspiration biopsy may help in diagnosis. Facial nerve injury is more likely if the tumour is deep, in multiple sites or involves extensive scar tissue. Radiotherapy is controversial, it should be considered if there has been tumour spillage following re-operation.
