Migration and apparent disappearance of silicone tube following treatment of nasolacrimal duct obstruction.
OBJECTIVE
To describe the unusual complication of migration and apparent disappearance of silicone tubes following intubation of the lacrimal drainage system.


METHODS
Interventional case reports.


METHODS
Report of two patients with an unusual tube migration process.


RESULTS
Silicone stents migrated nasally, with healing of the erosion tract in the wake of the migrating tube. One tube became completely internalized.


CONCLUSIONS
Meticulous inspection of the medial canthal area in patients with suspected spontaneous extrusion of silicone stents from the lacrimal drainage system is warranted. Examination under anesthesia and nasal endoscopy may help locate tubes in cases of suspected nasal migration.
