Successful Preservation of the Facial Nerve in Parotid Surgery for Huge Pleomorphic Adenoma of the Deep Lobe. A Case Report

Abstract

Pleomorphic adenoma, also known as benign mixed salivary gland tumor, is the most common salivary gland tumor accounting for about 50-74 percent of all parotid neoplasms that has a slight female predilection in the 4th to 5th decade of life. The treatment of choice for this tumor is complete surgical removal. When the tumor arises from the superficial lobe of the parotid gland, superficial parotidectomy is recommended with facial nerve preservation and if the tumor involves the deep lobe, in that case, it may be necessary to perform total parotidectomy with identification and preservation of the facial nerve. Here we are presenting a case of parotid (deep lobe) pleomorphic adenoma where we successfully preserved and identified the facial nerve with the complete removal of the tumor.
