Parotidectomy technique in the treatment of parotid tumours (an analysis of 70 cases).

A study of seventy different cases of parotid tumours, using subtotal as opposed to total parotidectomy in the treatment of benign tumours.

The accurate meaning of subtotal parotidectomy is defined, comparing its indications as opposed to total parotidectomy.
