Background and Objectives
Eyelid sagging is a common complaint in aging patients. Although various attempts have been made to treat this condition, obtaining satisfactory results in patients without causing adverse effects has been challenging. The study demonstrated that high-intensity focused ultrasound (HIFU) can be a valuable tool for the treatment of eyelid sagging.
Materials and Methods
Twenty Korean women aged 35 to 57 years with mild to moderate upper and lower eyelid sagging were enrolled. The periocular area of the participants was treated with a 2.0-mm, 4-MHz HIFU probe. Photographs were taken before and 12 weeks after the treatment. Two clinicians who were blinded to participant recruitment evaluated improvements. Perceived improvement was rated by both patients and clinicians on a 4-point scale. The eyelid length was measured and compared before and after treatment.
Results
The results showed that 17 patients (85%) experienced some clinical improvement. In 15 of the 20 cases, clinicians were able to detect improvement. In addition, the mean eyelid length was reduced 12 weeks after treatment, indicating that the treatment is a potentially effective method for successfully treating eyelid aging.
Conclusion
HIFU is a useful method for improving upper eyelid sagging.
