—There have been several recent descriptions of fixation techniques for monocanalicular silicone intubation. Braverman and Brown1 advocated externalizing the tubing along the nose in a continuous loop, while others have developed some form of internal eyelid fixation.2,3 Romano2 described suturing the free end of the silicone tubing either into the inferior fornix or near the caruncle. Gonnering3 recently reported a case using percutaneous fixation of the silicone tubing in the ampulla. Prior to these reports, we had independently developed a technique that includes some features of the latter two reports but has additional advantages, and we have used it successfully over the past years in six cases of infantile monocanalicular stenosis with follow-up of at least six months.After silicone tube intubation of the single canaliculus, a vertical one-snip punctaplasty down into the ampulla is performed. We then make a 4- to 5-mm
