Maximal Levator Muscle Resection for Primary Congenital Blepharoptosis with Poor Levator Function.

Area of Science:

• Ophthalmology
• Surgical Techniques
• Pediatric Eye Care

Background:

• Congenital blepharoptosis, particularly with poor levator muscle function, presents significant challenges in pediatric ophthalmology.
• Traditional surgical options like frontalis suspension may have limitations in certain cases.
• Evaluating alternative surgical methods is crucial for optimizing outcomes in affected children.

Purpose of the Study:

• To assess the clinical effectiveness of maximal levator resection surgery.
• To evaluate outcomes in pediatric patients diagnosed with congenital blepharoptosis and poor levator muscle function.

Main Methods:

• A prospective study involving 23 patients (29 eyelids) undergoing maximal levator resection.
• Pre- and postoperative measurements included eyelid skin crease, levator function (LF), rima palpebrarum (RP), and margin-reflex distance (MRD).
• Success was defined as a ≤1 mm difference between eyelids; satisfactory as 1-2 mm; poor as >2 mm.

Main Results:

• Postoperative measurements showed significant improvements in RP, MRD, and LF (p < 0.05).
• Successful outcomes (≤1 mm difference) were achieved in 60.9% of patients, with satisfactory results in 8.7% and poor results in 30.4%.
• All cases of abnormal head posture resolved post-surgery.

Conclusions:

• Maximal levator resection surgery is a potentially effective treatment for congenital blepharoptosis in pediatric patients with poor levator function.
• This technique may serve as a beneficial alternative to frontalis suspension surgery.
• The procedure demonstrated significant functional and aesthetic improvements, including the resolution of compensatory head postures.
