Comparison of Dermis Vs. Auricular Cartilage Grafts for the Surgical Correction of Lower Eyelid Retraction

Not Applicable
Completed
Conditions
Lower Eyelid Retraction
Registration Number
NCT06679439
Lead Sponsor
University of Sao Paulo General Hospital
Brief Summary

This study aimed to compare the effectiveness of two autologous grafts-dermis and auricular cartilage-in the surgical correction of the lower eyelid retraction. Our primary focus was assessing changes in lower eyelid position using lower eyelid Margin to corneal Reflex Distance measurements, a.k.a Margin reflex distance 2 (MRD2).

Detailed Description

This prospective, randomized interventional study includes patients with stable LER. Patients are randomly assigned to undergo surgical correction using either auricular cartilage or dermis grafts, with the vertical dimension configured to be twice the scleral show height. MRD2 measurements were taken pre-operatively and at several post-operative intervals, with complications and outcomes recorded.
