OBJECTIVE: To assess the impact of extent of parotidectomy on surgical and oncologic outcomes in low grade mucoepidermoid carcinoma (LGMEC).
METHODS: A retrospective chart review of all patients undergoing primary surgical treatment for LGMEC from 2000 to 2022 was conducted. Clinical features collected included demographics, facial nerve function, operative techniques, postoperative complications/facial nerve function, and recurrence.
RESULTS: 58 patients were included; 10 patients underwent partial parotidectomy (PP), 38 underwent superficial parotidectomy (SP), and 10 underwent near-total/total parotidectomy. PP and SP patients had smaller tumors and more superficial tumors compared to near-total/total parotidectomy group (P = .03). PP and SP were more likely to have negative margins and less locoregional disease compared to near-total/total parotidectomy patients (P < .01). Near-total/total parotidectomy were more likely to undergo facial nerve resection (20% vs 0% for PP & SP respectively) (P = .05). Immediate postoperative facial nerve function was significantly better among PP patients (73% HB I) compared to SP (44% HB I) and near-total/total parotidectomy patients (0% HB I) (P < .01). Most patients regained their facial nerve function although only 40% of the near-total/total parotidectomy patients had a HB I at the time of last follow up (P < .01). Patients were followed for a median of 6.2 years, during which only 1 patient (total parotidectomy) had a recurrence.
CONCLUSIONS: PP offers a safe and effective approach for small LGMEC tumors, ensuring better facial nerve function postoperatively with minimal complications compared to more extensive surgery.
