    Abstract:
    BACKGROUND: Recent modifications of surgical technique may have influenced outcome following parotidectomy. This retrospective study compares the results of the different surgical methods with regard to recurrence rate and the effects on morbidity between 1974 and 1994. METHODS: A total of 246 primary surgical parotid procedures were performed on 245 patients for pleomorphic adenoma. These included 131 'partial' superficial parotidectomies, 61 'total' superficial parotidectomies, 30 partial superficial/deep lobe parotidectomies, eight total parotidectomies, and 16 'selective' deep lobe parotidectomies. In the recent past, the posterior branch of the greater auricular nerve was preserved in the majority of patients. Eleven patients received postoperative radiotherapy. Median follow-up was 95 months. Fourteen patients died without recurrent tumour. RESULTS: Two patients (0.8 per cent) developed local recurrence, both after total parotidectomy for a deep lobe tumour. No patient experienced permanent facial nerve palsy. The incidence of gustatory sweating for partial superficial parotidectomy was 6.9 per cent (nine of 131) compared with 13.1 per cent (eight of 61) for total superficial parotidectomy. CONCLUSION: Partial parotidectomy is an effective treatment for the majority of pleomorphic adenomas; local recurrence is rare and morbidity is low. Prolonged follow-up is unnecessary.
