To investigate the clinical application of minimally invasive incision in the correction of mild and moderate ptosis.

A total of 76 patients with mild or moderate ptosis who underwent minimally invasive small-incision levator palpebrae superioris shortening combined with Muller's muscle shortening at the Plastic Surgery Center of Beijing Tongren Hospital Affiliated to Capital Medical University from May 2016 to March 2020 were analyzed retrospectively. Postoperative follow-up was conducted to evaluate the outcome and patient satisfaction.

After 6 months to 12 months of follow-up, most patients with mild and moderate ptosis had smooth double eyelid radian, and no obvious depression or scar on the incision line of eye closure, ptosis was effectively improved, and the satisfaction rate of postoperative effect was high. The effective correction rate was 93.3% (90 cases were completely corrected and 22 cases were improved), and the patient satisfaction rate was 85.5% (65/76).

Minimally invasive blepharoptosis correction has a positive clinical effect, relatively simple operation, little surgical trauma, and low incidence of complications.
