Evolution of the lateral canthoplasty: techniques and indications

Area of Science:

• Ophthalmology
• Plastic Surgery
• Periorbital Anatomy

Background:

• Lateral canthoplasty is crucial for restoring eyelid function and ocular surface protection.
• Procedure success hinges on precise periorbital anatomy analysis relative to the indication.
• Evolving techniques aim for greater anatomical and functional precision.

Purpose of the Study:

• To report the experience with 1565 lateral canthoplasties.
• To evaluate newer techniques for improved anatomical and functional outcomes.
• To discuss indications and procedural details for lateral canthoplasty.

Main Methods:

• A retrospective review of 1565 lateral canthoplasties performed between 1981 and 1994.
• Procedures were categorized into reconstructive (1369) and cosmetic (196) types.
• All surgeries were performed by a single surgeon with follow-up ranging from 1 to 14 years.

Main Results:

• The study involved 684 patients undergoing 1565 lateral canthoplasties.
• Reconstructive procedures were performed in 586 patients, cosmetic in 98.
• Techniques evolved towards individualized, anatomy-driven approaches.

Conclusions:

• Lateral canthoplasty techniques have advanced to better match individual anatomy.
• The procedure addresses various conditions including dystopia, laxity, ectropion, entropion, and retraction.
• Newer lateral canthoplasty forms serve as valuable reconstructive tools and adjuncts in aesthetic surgery.
