Abstract

Most studies that examine postoperative outcomes after parotidectomy in patients with benign parotid gland tumors are based on retrospective chart reviews. Data about long-term results in patients with parotid gland surgery with patient contact are still sparsely published. During the period of 1960-2005, a total of 127 patients underwent either extracapsular dissection (ECD) or superficial parotidectomy (SP) and were available for interview. Patients were questioned about their postoperative outcome after parotid gland surgery. The mean follow-up was 21.5 years. A total of 42 and 85 patients underwent ECD and SP, respectively. No significant differences were observed in the rates of permanent facial paralysis (SP 1.2% vs. ECD 7.1%; p = 0.1053) or recurrence (SP 4.7% vs. ECD 11.9%; p = 0.1557), and Frey's syndrome was diagnosed only after SP (10.6% vs. 0% after ECD, p = 0.0293). Frey's syndrome was detected more often compared to retrospective chart analysis. We conclude that Frey's syndrome is underdiagnosed after SP without standardized follow-up examinations. Long-term follow-up should be applied to detect and treat gustatory sweating. Copyright © 2020. Published by Elsevier Ltd.
