Summary
This study presents a modified Fasanella-Servat procedure for correcting minimal eyelid ptosis. The technique offers a safe and effective solution, achieving good results in 95% of cases with minimal complications.
Area of Science:
- Ophthalmology
- Oculoplastic Surgery
Background:
- Blepharoptosis, or drooping eyelids, can affect vision and aesthetics.
- Existing surgical techniques for ptosis correction vary in complexity and outcomes.
- Minimal ptosis (< 2.5 mm) with good levator function requires precise and minimally invasive treatment.
Purpose of the Study:
- To describe a modified Fasanella-Servat procedure for correcting minimal blepharoptosis.
- To introduce a nomogram to guide tarsectomy amount based on ptosis severity.
- To evaluate the efficacy and safety of this modified technique.
Main Methods:
- Retrospective review of 118 eyelids in 86 patients undergoing the modified Fasanella-Servat procedure.
- Tarsectomy amount was determined by the degree of ptosis.
- Surgical outcomes were assessed by margin-to-reflex distance (MRD1) and eyelid symmetry.
Main Results:
- Mean MRD1 improved from +0.7 mm to +2.4 mm post-surgery.
- 95% of eyelids achieved satisfactory MRD1 (≥ 1.5 mm).
- 92% achieved excellent eyelid symmetry (within 0.5 mm); low complication rate reported.
Conclusions:
- The modified Fasanella-Servat procedure is technically straightforward, efficient, and safe for minimal blepharoptosis.
- It demonstrates a low complication rate, making it a valuable addition to ptosis surgery options.
- The technique, with a tarsectomy to eyelid elevation ratio of approximately 2:1, is a useful adjunct for ptosis surgeons.
