|August 1, 1983
Summary
Conjunctivodacryocystorhinostomy using buccal mucosa lining for obstructed lacrimal canaliculi shows promising results. While some patients experienced tube complications, lining the fistula with buccal mucosa promoted stable, mucous membrane-lined tracts post-tube removal.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Reconstructive Surgery
Background:
- Obstructed lacrimal canaliculi cause epiphora and affect quality of life.
- Traditional dacryocystorhinostomy techniques may have limitations in long-term fistula patency.
- The use of mucosal grafts in dacryocystorhinostomy is an area of ongoing research.
Purpose of the Study:
- To evaluate the efficacy and outcomes of conjunctivodacryocystorhinostomy (CDCR) modified with buccal mucosa lining.
- To assess the long-term patency and complications associated with this modified surgical technique.
Main Methods:
- Eleven patients with obstructed lacrimal canaliculi underwent modified CDCR with buccal mucosa lining.
- Surgical technique involved lining the fistula with buccal mucosa during the CDCR procedure.
- Patients were followed for varying periods, with some tubes removed after six months.
Main Results:
- Four patients with tube removal after six months maintained mucous membrane-lined fistulas with 10-13 months follow-up.
- One patient whose tube was removed early had immediate fistula closure.
- Six patients retaining tubes were free from epiphora but experienced complications like extrusion, migration, and irritation.
Conclusions:
- Lining the fistula with buccal mucosa in CDCR appears to promote stable, mucous membrane-lined fistulas.
- While tube retention avoids epiphora, it carries risks of complications.
- This modified technique offers a potential solution for maintaining fistula patency after dacryocystorhinostomy.
