ABSTRACT
Between 1973 and 1988, 302 patients underwent surgical operations for parotid gland swelling. Primary operations were performed in 293 cases, while secondary operations for recurrent tumour were performed in nine cases. A total of 244 patients (80.8%) were found histologically to have either a benign parotid tumour or a tumour-like lesion, while 58 patients (19.2%) were diagnosed as having malignant tumours. Two hundred and eighty-nine patients underwent superficial and total conservative parotidectomy and in 13 cases a radical parotidectomy was performed. The median follow-up was 5 years (range 1-15 years). Permanent facial nerve palsy, tumour recurrence, Frey's syndrome and parotid fistula were recorded as 0.7, 0.7, 2.1 and 0.4%, respectively. Thus, with full understanding of the surgical anatomy of the parotid gland and correct tumour identification, preservation of the facial nerve and serious postoperative complications can be minimized following superficial and/or total conservative parotidectomy.
