Objectives/hypothesis: To determine immediate postoperative and long-term facial nerve dysfunction after parotid cancer surgery, risk factors, and the role of facial reanimation surgery., Study Design: Population-based long-term analysis for all new primary parotid carcinoma cases in Thuringia from 1996 to 2019., Methods: Data of the cancer registries of Thuringia, a federal state in Germany, were analyzed in combination with hospital-based data on facial function., Results: About 477 patients (42.3% women; median age: 68 years) were included. It was observed that 6.7% had a preoperative facial nerve dysfunction, 11.7% received a radical parotidectomy, that is, that 5% had a normal preoperative facial function but needed radical surgery because of intraoperative detection of tumor infiltration into the facial nerve. About 10.2% received facial nerve reconstruction surgery. Immediate postoperative facial nerve dysfunction in the other patients was observed in 34.4% of the patients. Advanced T classification (odds ratio [OR] = 2.140; confidence interval [CI] = 1.268-3.611; P = .004) and neck dissection (OR = 2.012; CI = 1.027-3.940; P = .041) were independent risk factors for immediate postoperative facial nerve dysfunction. In addition, 22.0% showed no recovery during follow-up. Advanced T classification (OR = 2.177; CI = 1.147-4.133; P = .017) and postoperative radiotherapy (OR = 2.695; CI = 1.244-5.841; P = .012) were independent risk factors for permanent postoperative facial nerve dysfunction., Conclusion: Patients with primary parotid cancer are at high risk for long-term facial nerve dysfunction. It seems that the possibilities of facial reanimation surgery needs to be utilized even more effectively., Level of Evidence: 3 Laryngoscope, 131:2694-2700, 2021., (© 2021 The Authors.

Background: The ideal extent of surgical intervention for benign parotid tumors remains a matter of controversy. The purpose of this study was to examine the existing arguments against extracapsular dissection and present our experience over the last 16 years., Methods: A retrospective evaluation was carried out on the records of all patients who underwent extracapsular dissection for benign parotid tumors at a tertiary referral center between 2000 and 2015., Results: A total of 1359 cases were included in the study. Temporary postoperative facial palsy was detected in 68 cases (5%), permanent facial palsy in 5 cases (0.37%), and postoperative Frey's syndrome in 31 cases (2.3%). Recurrences of pleomorphic adenomas were shown in 4 cases (0.87%)., Conclusion: Our analysis could not justify the arguments against correctly indicated implementation of extracapsular dissection and showed that increased performance of this modality was associated with excellent oncologic and functional outcomes. © 2016 Wiley Periodicals, Inc.
