Canalicular resection and reconstruction by canaliculostomy
Ophthalmic Surgery
|July 1, 1980
Summary
This study introduces a new canaliculostomy technique to treat epiphora (watery eyes) after lower eyelid surgery. The procedure effectively externalizes remaining tear drainage channels, providing relief for patients.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Reconstructive Surgery
Background:
- Lower eyelid resection can compromise the lower canaliculus, leading to epiphora.
- Existing techniques may not fully address residual canalicular tissue after lower lid surgery.
- Effective management of the lower canaliculus is crucial for tear drainage.
Observation:
- A novel canaliculostomy technique externalizes residual lower canaliculus via an ostomy.
- The procedure utilizes silicone intubation of the residual stump and upper canaliculus.
- Micro-dissection and placement on the eyelid margin are key steps.
Findings:
- The described canaliculostomy technique successfully treated epiphora in all patients.
- As little as one-fourth of the residual canaliculus can be utilized.
- Physiologic tear flow was documented in some cases using the Jones No. 1 dye test.
Implications:
- This technique offers a viable solution for epiphora following lower eyelid resection.
- It can be combined with various eyelid reconstructive procedures.
- The method is applicable to diverse conditions including neoplastic disease, cicatricial deformities, and congenital abnormalities.
