Abstract

The article’s aims to evaluate the results of primary repair and reconstruction of defects after resection of benign parotid tumors using autologous dermal fat grafts, Our study was performed in 15 patients who underwent surgery at the Department of Head and Neck Surgery, Maxillofacial Surgery - Ho Chi Minh City Oncology Hospital from October 2023 to October 2024 with a follow-up period of 6 months. The average volume of the resected tumor in the study was 19.1 ± 3.7 cm3, the dermal fat graft was 27.0 ± 4.5 cm3 and the excess was about 41.6 ± 9.8%. Follow-up by MRI and ultrasound both showed that the rate of graft fat resorption increased over time, after 6 months this rate was 45.6% on ultrasound and 50.6% on MRI. The volume of graft dermal fat and the degree of fat loss were statistically significantly proportional, with the correlation ratio after 6 months on ultrasound being r=0.692 (p=0.004) and on MRI being r=0.835 (p<0.001). There were no cases of Frey syndrome, only 2 cases of seroma complications. The satisfaction level after surgery was high, after 6 months the rate of very satisfied doctors was 93.5% and patients was 86.7%. Primary repair and reconstruction of the defect after resection of benign parotid gland tumors with autologous dermal fat grafts helps ensure facial aesthetics and prevent Frey syndrome. This surgical method is simple, safe, suitable for the size of the defect, has few complications, and has little impact on the donor site.
