ABSTRACT
OBJECTIVE: The extent of surgery in benign superficial parotid tumors has no strong evidence-based consensus. Partial superficial parotidectomy (PSP) is a popular choice among surgeons. We retrospectively evaluated the hypothesis that it carries similar efficacy and greater safety than superficial parotidectomy (SP). PATIENTS AND METHODS: Between 2010 and 2016, 84 patients with benign superficial parotid tumors were enrolled in the study. Deep lobe and recurrent tumors were excluded. The patients were treated by SP; (40 patients) or PSP; (44 patients). The operative and postoperative morbidity, tumor recurrence, operative time, and length of hospitalization were analyzed. RESULTS: There was no significant difference regarding patients or tumors in baseline data. PSP showed significantly shorter operative time (P = .022), and hospital stay (P = .001), as well as significantly lower frequencies of postoperative transient facial nerve paralysis and Frey's syndrome, (P = .042 for each). Permanent facial dysfunction was nonsignificantly greater in SP. No tumor recurrence was detected in either group after a median follow-up of 7 years. CONCLUSIONS: PSP is a quicker and less extensive procedure. It was associated with a shorter hospital stay and fewer complications especially transient facial paralysis and Frey's syndrome with a recurrence rate comparable to that of SP.
