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 parallelism 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.

Facial Nerve Paralysis due to a Pleomorphic Adenoma with the Imaging Characteristics of a Facial Nerve Schwannoma

“…Patients with facial nerve weakness had a poorer prognosis, with a 5-year survival rate of only 9%. 3 In 2011, Wierzbicka et al reported an incidence of facial nerve weakness of 31% of patients (32 of 103) with parotid gland malignancies. In this series, patients with facial nerve weakness had a 3-year disease-free survival rate of 45%, compared with 88% in those without any facial nerve paresis.…”

Isolierte Paresen der Fazialisendäste - Klinische Befunde, Ursachen und Differenzialdiagnose

“…1 Paresen der Fazialisendäste; Ursachen und Prognose Parese des M. frontalis links.Originalarbeit folglich auf iatrogenen Schäden, die im Gesamtspektrum mögli− cher Ursachen auch zu überwiegen scheinen.Publikationen zur Prävalenz spontaner Fazialisendastparesen sind dagegen rar und beziehen sich speziell auf Tumoren der Ohrspeicheldrüse. In einer multizentrischen Studie an 1029 Pa− tienten mit Parotiskarzinomen haben Eneroth u. Mitarb [14]. in 14 % der Fälle präoperative Fazialisparesen diagnostiziert, die al− lerdings nicht genauer definiert werden und wohl eher komple− xer Natur gewesen sind.…”
