[Surgical treatment of tumors of the parotid gland (author's transl)].

One hundred and thirty-one cases of patients operated for a parotidal tumor were reviewed. We report on 85 cases that had no previous treatment, including 68 benign and 17 malignant tumors. The surgical treatment applied is analysed according to the benign or malignant nature of the tumor and to the results. For benign mixed tumors (43 cases) there were 29 total resections, 12 superficial lobectomies and 2 simple enucleations (intraparotidal location unforseen). For tumors of Warthin (19 cases) the treatment was a superficial lobectomy in all cases. For malignant tumors (17 cases) 5 superficial lobectomies and 12 total resections of the gland were performed. In the latter, the facial nerve was severed in 6 patients and left intact in the other 6. The minimal operation realizing the resection of a parotidal tumor, is the superficial lobectomy realized in once, the deep lobe only being resected if invaded. Preservation of the facial nerve should always be tried, sacrificing it only in cases of infiltrating malignant tumor.
