Summary

This study introduces a new surgical technique for reconstructing the lacrimal drainage system in medial eyelid defects. Canalicular transposition proved successful in restoring function after eyelid tumor removal.

Area of Science:

  • Ophthalmology
  • Reconstructive Surgery
  • Oncology

Background:

  • Medial eyelid defects frequently compromise the lacrimal drainage system, presenting significant reconstructive challenges.
  • Reconstruction of the lacrimal drainage system is crucial for maintaining ocular surface health and tear drainage.

Observation:

  • A 67-year-old female patient with medial left lower eyelid sebaceous cell carcinoma underwent tumor excision, including the lacrimal punctum and canaliculus.
  • The remaining portion of the canaliculus was surgically transposed to the eyelid margin.

Findings:

  • The described canalicular transposition technique successfully reconstructed the medial eyelid defect.
  • Postoperative follow-up at 1 year confirmed the patency and functionality of the transposed canaliculus.

Implications:

  • This novel technique offers a viable solution for medial eyelid defects involving the lacrimal drainage system.
  • Successful canalicular reconstruction can improve patient outcomes and quality of life by restoring tear drainage.
