Moreover, the tendency of malignity of the benign mixed tumors can make histological results invalid in long terms. Aims: Decribing clinical features, radiography results and assessment of parotid mixed tumors surgical treatment with preservation of facial nerve. Patients and methods: 36 patients with diagnosis of parotid mixed tumors and treatment of tumors resection with the preservation of facial nerve at the Odonto-Stomatology Department in Hue Central Hospital during the period of time from January 2020 to September 2021.

Rate of the left sites is 52.8%, tumors size ranged 2-4cm is 66.7%, high density (firm) is 83.3%. Site on the superficial lobe accounts for 75% (most common). Ultrasound features show 100% of hypoecho, 75% of high homogeneity. CT scan features show 55.6% on the superficial lobe, 63.9% of high homogeneity. Treatment outcomes: good 83.3%, fair 16.7%.
