Objective: An examination of the impact of ultrasound-assisted liposuction and the formation of the abdomen"s vest line. Method: Selected from January 2022 to December 2024, sixty patients requiring abdominal liposuction and shaping were randomly divided into two groups: an experimental one and a control one, with 30 each. The control group was given conventional liposuction shaping, while the experimental group was given ultrasound assistance to compare the effects. Result: The experimental group"s satisfaction rate was 96.67%, a figure that was higher than the control group"s 70%, P<0.05. Prior to treatment, no distinction in upper and lower abdominal circumference was observed between the two groups, P>0.05. After treatment, however, the experimental group"s upper and lower abdominal circumference were lower than the control group"s, P<0.05. Additionally, the experimental group"s incidence of adverse reactions was 3.33% lower than the control group"s 26.67%, P<0.05. Lastly, no difference in negative emotions between the two groups was found prior to treatment, P>0.05. However, after treatment, the negative emotions in the experimental group were lower than those of the control group, P<0.05.Conclusion: The utilization of ultrasound to assist in liposuction and the formation of a vest line has been found to be beneficial, leading to high patient satisfaction and safety, thus effectively diminishing negative emotions in patients.
