Objective To explore the effect of microfocused ultrasound technology combined with sodium hyaluronate filling on facial morphology recovery in patients with facial aging. Methods A total of 60 patients with facial aging admitted to Sichuan Huamei Zixin Plastic Surgery Hospital from September 2023 to March 2024 were selected as the research subjects, and they were divided into the control group and the observation group according to different treatment methods, with 30 patients in each group. The control group was treated with sodium hyaluronate filling, and the observation group was treated with microfocused ultrasound technology combined with sodium hyaluronate filling. The facial morphology recovery, maintenance time of facial improvement effect, adverse reaction rate and satisfaction were compared between the two groups. Results The excellent and good rate of the observation group (96.67%) was higher than that of the control group (80.00%) (P <0.05). The maintenance time of facial improvement effect in the observation group was longer than that in the control group (P <0.05). The incidence of adverse reactions in the observation group (6.67%) was lower than that in the control group (26.67%) (P <0.05). The satisfaction rate of the observation group (76.67%) was higher than that of the control group (50.00%) (P <0.05). Conclusion Microfocused ultrasound technology combined with sodium hyaluronate filling shows good comprehensive advantages in facial rejuvenation treatment. It can effectively promote the natural recovery of facial morphology, with long-lasting and stable improvement effect. The treatment process is safe and reliable, with low incidence of adverse reactions, and has been highly recognized and satisfied by patients.
