[Clinical study of surgically treated parotid tumors during 1981-1985]

There is a great histologic diversity in parotid tumors. Four categories can be distinguished: pleomorphic adenoma, monomorphic adenomas, low-grade malignant tumors and high-grade malignant tumors. The most current neoplasm is the pleomorphic adenoma. The first three groups have a nearly similar clinical evolution and surgical treatment. The high-grade malignant tumors often cause a facial nerve paralysis and require a radical approach.
