An approach to malignant parotid tumours.
A series of 30 patients with malignant parotid tumours selected for surgical treatment is presented. There were 18 males and 12 females, with an age range of 12-80 years. All presented with a parotid lump, one had an associated painful facial nerve palsy and one had clinically involved neck nodes. Four had previous surgery, surgical biopsy or radiotherapy. Pre-operative fine needle aspiration was performed on one patient. Postoperative radiotherapy was administered to 14 patients. Follow-up was for a mean of 5.5 years. The primary tumour was controlled by surgery alone in 15 of the 16 patients. There was one local recurrence and two patients in this group died from distant metastases. Of the group receiving postoperative radiotherapy, there was one local recurrence, one local and neck recurrence and one death from distant metastases. Mobile, discrete tumours can be treated by parotidectomy with preservation of the facial nerve and the selective use of radiotherapy. The malignant tumour with restricted mobility but no facial palsy is treated by parotidectomy, sacrificing only involved branches and postoperative radiotherapy. The clinically fixed lesions with facial palsy demand total parotidectomy in operable cases, nerve sacrifice and postoperative radiotherapy.
