[Results of surgical treatment of benign and malignant parotid tumors (author's transl)].

Of the total of 241 parotid tumors surgically treated between 1956 and 1975 at the Clinic of Otorhinolaryngology, Karl Marx University at Leipzig, 190 were of benign and 51, of malignant character. Patients of advanced age showed preferential development of parotid tumors. In more than ninety percent of the cases, the results of sialography were in agreement with surgical results. Surgical removal of the entire parotid gland was performed with the exception of those cases where the tumor showed good encapsulation and was confirmed to the pars superficialis of the parotid gland. Three cases of complete, permanent facial palsy resulted from surgical treatment of 190 cases of benign parotid tumors. The prognosis of malignant parotid tumors is extremely bad, and it is characterized by a proportion of successful surgical operations of only 26.5 percent.
