Methods: The surgical findings and clinical data of patients with aponeurotic ptosis who underwent small incision or standard levator advancement surgery in our clinic between 2018 and 2020 were analyzed retrospectively. For both groups; age, gender, systemic and ophthalmic comorbidities, levator function, preoperative and postoperative margin-reflex distance, change in margin-reflex distance after surgery, symmetry between the eyes, follow-up time, perioperative and postoperative complications (under/overcorrection, contour irregularity, lagophthalmos) were all evaluated and recorded. Results: The study included 82 eyes, 46 from 31 patients in Group I who had small incision surgery, and 36 from 26 patients in Group II who had standard levator surgery. There was no statistically significant difference in surgical success between the two groups (80% and 81% respectively, p = 0.692). The levator function and preoperative margin-reflex distance correlated positively with surgical success. Conclusion: Small incision levator advancement is a less invasive procedure than standard levator advancement because of the smaller skin incision and preservation of orbital septum integrity, but it requires good knowledge of eyelid anatomy and experience in eyelid surgery. In patients with aponeurotic ptosis, this surgery can be performed as a safe and effective surgical technique with a similar success rate as standard levator advancement.
