Summary

Precaruncular medial canthopexy (PMC) is a new 3D technique that effectively corrects medial eyelid malposition. This safe and rapid procedure offers excellent wound healing and symptom relief for patients.

Area of Science:

  • Oculoplastics
  • Ophthalmic Surgery
  • Reconstructive Surgery

Background:

  • Eyelid malposition, including ectropion and entropion, can significantly impact vision and quality of life.
  • Current surgical techniques for medial canthal repositioning may have limitations in restoring 3D support.
  • Facial paralysis is a common cause of lower eyelid malposition.

Purpose of the Study:

  • To introduce and describe a novel 3-dimensional surgical technique for medial canthal repositioning: precaruncular medial canthopexy (PMC).
  • To evaluate the efficacy and safety of PMC in correcting medial eyelid malposition through an outcome study.

Main Methods:

  • Prospective data collection on patients with lower eyelid malposition, including demographics, etiology, and symptoms.
  • Standardized pre- and post-operative photography.
  • Ectropion Grading Scale (EGS) used for objective assessment of eyelid position.
  • Surgical outcomes assessed by objective EGS improvement and subjective symptom resolution.

Main Results:

  • PMC was performed on 30 eyelids in 27 patients, with 10 cases being revisions.
  • The most frequent indication was ectropion (n=26), often secondary to facial paralysis (n=21).
  • Twenty-eight procedures achieved complete medial canthus restoration (EGS grade I), with two cases showing minimal residual scleral show (EGS grade II) but symptom relief. No complications were reported.

Conclusions:

  • Precaruncular medial canthopexy (PMC) is a rapid, safe, and effective 3D technique for restoring medial canthal support.
  • The procedure demonstrates minimal morbidity, excellent wound healing, and does not compromise the visual field or lacrimal system.
  • PMC is valuable as a primary treatment for medial eyelid malposition and as an adjunct for lateral malposition correction.
