BACKGROUND: Extracapsular dissection (ECD) of parotid tumors is reported to carry less morbidity than superficial partotidectomy (SP). It is a procedure recommended for benign tumors of the parotid gland. We aimed to retrospectively analyze the difference in postoperative complications between ECD and SP for benign cases over an 11-year period. Endpoints compared were; facial nerve weakness transient and permanent, Frey Syndrome, sialocele and recurrence.
METHODS: A total of 190 cases were identified in 182 patients; 67 ECD procedures were performed and 123 SP. The patients were followed up for an average of 1 year and 3 months.
RESULTS: The results showed a higher percentage of all complication endpoints assessed in SP when compared to ECD respectively; transient facial nerve weakness (17.1% vs. 6%), permanent facial nerve injury (in malignant tumors, perineural involvement cases were excluded) (10.6% vs. 7.5%), greater auricular nerve damage (36.3% vs. 31.3%), sialocele development (5.7% vs. 3%), Frey Syndrome (3.3% vs. 0%) and recurrence (1.6% vs. 1.5%).
CONCLUSIONS: ECD has better outcomes for patients and when feasible, in the setting of benign tumors in the superficial lobe of the parotid gland, it should be considered.
