Long-Term Follow-Up of Lateral Canthal Resuspension.

Area of Science:

• Ophthalmology
• Plastic Surgery

Background:

• Lateral canthal resuspension is a surgical technique to correct eyelid laxity and improve aesthetic outcomes.
• Evaluating the long-term efficacy of this procedure is crucial for patient satisfaction and surgical planning.

Purpose of the Study:

• To assess the long-term results and durability of lateral canthal resuspension.
• To quantify changes in key eyelid measurements over time following the procedure.

Main Methods:

• A cohort study involving adults who underwent lateral canthal resuspension.
• Measurements included marginal reflex distance 2 (MRD2), inferior scleral show, lateral canthal height, angle, horizontal palpebral aperture, and lateral scleral triangle area.
• Data were collected preoperatively and at multiple postoperative time points up to final follow-up (mean 15.1 months).

Main Results:

• Significant long-term improvements were observed in MRD2, inferior scleral show, and lateral canthal height.
• The overall effect of time was significant for changes in MRD2 and lateral canthus position.
• No significant complications were reported, indicating a safe procedure.

Conclusions:

• Minimally invasive lateral canthal resuspension provides durable, modest aesthetic improvements.
• The procedure effectively enhances MRD2, reduces inferior scleral show, and increases lateral canthal height.
• Key aesthetic parameters like lateral canthal angle and palpebral aperture remained largely unchanged.
