This study introduces a safe lateral canthoplasty technique to widen eyes, achieving a 3mm extension with minimal complications. The method ensures a natural look by maintaining lower eyelid gray line continuity.

Area of Science:

  • Oculoplastic surgery
  • Cosmetic surgery
  • Facial aesthetics

Background:

  • Lateral canthoplasty is popular in Korea for widening the palpebral fissure.
  • Standard techniques can lead to complications like eyelid eversion and scarring.
  • A need exists for safer, more effective lateral canthal lengthening methods.

Purpose of the Study:

  • To present a novel, safe, and effective lateral canthoplasty technique.
  • To minimize complications associated with lateral canthal lengthening.
  • To achieve natural-looking, extended palpebral fissures.

Main Methods:

  • A total of 236 patients underwent the modified lateral canthoplasty between 2007 and 2015.
  • A triangular flap was elevated 4-5 mm from the lateral canthus and rotated 45 degrees laterally.

  • The flap was fixated to the lateral orbital rim, maintaining lower eyelid gray line continuity with minimal tension.

    • Main Results:

    • Satisfactory lateral canthal extension was achieved in over 95% of cases.
    • An average lateral canthus extension of 3 mm was obtained.
    • Minor complications like wound dehiscence and scarring were easily corrected.

    Conclusions:

    • The described technique effectively lengthens the lateral canthus, providing a natural triangular shape.
    • Maintaining lower eyelid gray line continuity minimizes complications such as webbing and conjunctival exposure.
    • This method offers a safe and reliable approach to lateral canthoplasty with high patient satisfaction.
