The surgeon then sutures this loop of silicone tubing to the nasal septum or lateral alar cartilage internally.3 In their two patients, the authors found that the silicone tubes "cheese wired" through the puncta, migrating nasally for a considerable distance, with complete healing of the erosion tract.
