Parotid tumor operations; the case against enucleation.

Abstract

So-called mixed "encapsulated" parotid tumors are best managed by surgical procedures which avoid contact with the "capsule." Enucleation is often a hazardous and incomplete procedure. Subtotal or total parotidectomy with exposure of the facial nerve to avert accidental damage to it is the treatment of choice. Microscopic study of the periphery of such tumors reveals that the "capsule" does not fully encapsulate; hence, enucleation and lesser procedures may leave neoplastic tissue behind.Surgical procedures to achieve complete excision without endangering the facial nerve were carried out in 123 cases. There was local recurrence in one case.
