Abstract

Summary Supported by the author's experience, the problems of diagnosis and treatment of parotid tumours are presented. When operating the most frequent type of parotid tumour, which is the mixed tumour, the author performs a total parotidectomy. The same surgical procedure is also indicated in cases of persistent chronic parotitis and sialoadenosis. — Most importantly in parotidectomy is the exposure of the facial nerve and its branches in the parotid gland. The author prefers to commence operation by first exposing the trunk of the facial nerve, which is then followed towards the periphery. The main trunk of the facial nerve is constant, but its branches show variations in their number, thickness and position. The course and further divisions of the nerve may be variable. Bifurcation, trifurcation or even plurifurcation have been observed. The two main divisions, temporofacial and cervicofacial branches, with their variety in subdiving into the periphery, are described. A special description of the diversity in origin, position and number of the buccal branches with multiple intercommunicating, dividing and reuniting branches is offered.
