Abstract This retrospective cohort study aimed to evaluate the oncologic safety and functional outcomes of extracapsular dissection (ECD) as the primary surgical approach in patients with low-grade malignant parotid tumors. Conducted at a tertiary academic center, the study included 17 patients treated with ECD between 2012 and 2020, all of whom had preoperative benign or non-diagnostic cytology and were followed for at least 60 months. The primary outcome measures included recurrence rate, need for additional surgery or adjuvant therapy, facial nerve preservation, and disease-free survival. With a mean follow-up of 89.7 months, no local or regional recurrence was observed. ECD alone was sufficient in 76.5% of cases; three patients underwent completion superficial parotidectomy due to positive margins, yet no residual tumor was identified. Only two patients (11.8%) required adjuvant therapy due to perineural invasion. All patients maintained normal facial nerve function, and two died from unrelated causes while the remainder remained disease-free. These findings suggest that in carefully selected patients with small, well-circumscribed, low-grade parotid malignancies, ECD may provide oncologic outcomes comparable to more extensive surgery while minimizing surgical morbidity. ECD thus represents a viable definitive treatment option aligned with evolving, risk-adapted approaches to salivary gland cancer management.
