Modified Levator Resection Technique for Moderate Congenital Blepharoptosis

Area of Science:

• Ophthalmology
• Surgical Techniques

Background:

• Standard levator resection for moderate ptosis has limitations including residual lagophthalmos, undercorrection, and eyelid contour abnormalities.
• These issues necessitate modifications to improve surgical outcomes and patient satisfaction.

Purpose of the Study:

• To introduce and evaluate a modified levator resection technique for moderate congenital blepharoptosis.
• To assess the efficacy of the modified technique in improving eyelid function and reducing complications.

Main Methods:

• A modified levator resection technique involving sufficient levator muscle release, conjunctival support preservation, and multiple suture sites was applied to 57 patients (81 eyes).
• Preoperative and postoperative data, including margin reflex distance 1 (MRD1), levator function (LF), residual lagophthalmos (RL), patient satisfaction, and complications, were collected and analyzed.

Main Results:

• The modified technique significantly increased mean MRD1 and LF postoperatively.
• Successful ptosis correction was achieved in 95.1% of eyes, with 88.9% demonstrating excellent or good eyelid closure.
• Patient satisfaction was high (94.7%), and no major complications like hematoma, infection, or keratitis were observed.

Conclusions:

• The modified levator resection technique is effective for moderate congenital blepharoptosis.
• This approach successfully corrects ptosis while minimizing common complications and enhancing eyelid contour and function.
