Malignant parotid gland tumors and facial nerve paralysis

During the last three decades, 586 cases of parotid gland tumor have been extirpated in our clinic. The tumors were malignant in 170 cases and, of these, facial nerve paralysis was observed at first examination in 59 patients. This paper deals with the retrospective study of these cases and is chiefly concerned with the histological types and facial nerve paralysis.
