Diagnosis and Management of Parotid Tumors

Abstract

It is commonly accepted that the management of parotid tumors calls for complete resection of the growth. But beyond this there is little agreement and the literature on the subject contains many contradictory statements. Perhaps the most vexing problem is whether mixed and low-grade mucoepidermoid tumors are benign or malignant. The decision is largely based on the likelihood of recurrence at the primary site; yet such recurrences depend not only on the growth potential of the tumor, but also on the surgical technique employed in extirpation of the mass. If any vestige of the diseased tissue is permitted to remain, the second appearance may clinically be classified as a recurrence, but, strictly speaking, it is a continuation of the uncontrolled original process. The first prerequisite for successful management of parotid tumors is correct assessment of the extent of involvement. Often it is assumed that mere enucleation of "encapsulated" mixed tumors
