title: Preoperative facial paralysis in malignant parotid tumours.
abstract: Preoperative paralysis of the facial nerve was found in 145 of 1,029 patients with malignant parotid tumours (14%) treated at nine university clinics in Scandinavia. The incidence of facial paralysis varied between the different clinics. A parellelism between the incidence of the facial paralysis and the impairment of the prognosis of the different tumour types is shown. The presence of preoperative facial nerve paralysis in malignant parotid tumours implies a very poor prognosis but the situation is not as hopeless as has been suggested and therefore one must rely on very radical surgery.
