Parotidectomy for primary nonparotid diseases.

Abstract

To analyze the indications and results of parotid gland resections for patients with primary nonparotid diseases. Retrospective analysis of 442 consecutive parotidectomies (76 for primary nonparotid disease) in a referral head and neck surgery service, tertiary care university hospital. Skin cancer (mainly squamous cell and basal cell carcinomas) was the most common indication for parotidectomy. Superficial parotidectomy with preservation of the facial nerve was the most commonly performed operation (61.8%), with some form of nerve sacrifice necessary in 31.6%. Parotid gland parenchyma and/or lymph nodes were pathologically positive in 46 cases. Neck dissections were carried out in conjunction with parotidectomy in 42 patients (1 patient had had previous neck dissection), of which 16 turned out to be pN+. Parotidectomy should be considered as part of the surgical treatment of tumors whenever oncologically necessary for appropriate margins, lymph node dissection, and for proper identification and preservation of the facial nerve.
