Benign parotid lesions: is near total parotidectomy justified?

INTRODUCTION: Benign tumours of the parotid gland constitute about 80% of parotid tumours. The most common benign tumour of the parotid gland is pleomorphic adenoma. Other conditions, like Kimura's disease, may mimic a tumour when they present as a parotid mass. Various modes of treatment have been advocated for the treatment of benign parotid lesions, ranging from enucleation to near-total parotidectomy.

MATERIAL AND METHODS: This is an audit of an 18-year period where 173 lesions of the parotid gland (34 malignant and 139 benign lesions) were treated by the author.

RESULTS: There were 139 benign lesions, of which 123 were benign tumours and 16 non-tumour conditions. Fourteen cases of recurrent pleomorphic adenoma of parotid that had been treated elsewhere were also operated on. Near-total parotidectomy was performed on all these cases with benign lesions.

CONCLUSIONS: There has been no recurrence in all the patients who was treated this way. Near-total parotidectomy should be considered when there is a need to treat benign parotid swellings.
