Importance Electrophysiologic facial nerve monitoring is becoming an established intraoperative aid to assist the surgeon in facial nerve trunk or branch location and dissection. Limited studies have addressed the postoperative outcomes of parotid surgery with and without monitoring. Objective To examine the influence of intraoperative facial nerve monitoring on postoperative facial nerve function and procedure duration in parotid surgery. The study analyzed patients undergoing parotidectomy without monitoring from January 1, , to December 31, , and patients undergoing parotidectomy with monitoring from January 1, , to December 31,

For many people with parotid gland tumors, surgery performed by a head and neck surgeon is the main treatment. This operation is called a parotidectomy. The parotid gland consists of two lobes: the superficial lobe and the deep lobe. Surgery to remove a tumor in the superficial lobe is called a superficial parotidectomy.

Study design: A retrospective unicentric study in a tertiary care center with prospective record of studied factors. Methods: Over a year period, patients with normal facial nerve function underwent a superficial or total conservative parotidectomy with nerve dissection performed by one surgeon for primary benign or malignant tumors. Facial nerve function was assessed on the first postoperative day and at 1 month and 6 months after the parotidectomy. Extent of surgery, histopathological findings, tumor size, close contact of tumor with facial nerve, and sex and age of the patient were reviewed. These variables were studied in a chi2 statistical univariate and stratified analysis to determine their association with postoperative facial nerve dysfunction.
