%X <B>OBJECTIVE: </B>To describe a surgical technique for functionally reconstructing a lacrimal drainage duct and to assess its long-term functionality.<BR><B>METHODS: </B>This observational review includes six cases involving reconstruction of the inferior canaliculus after surgical resection of lower eyelid carcinoma. Following lesion excision with safety margins, the epithelium of the distal portion of the inferior canaliculus is located and intubated with a monocanalicular probe. Subsequently, the eyelid lamellae are reconstructed without displacing the probe. The Monoka collarette is then sutured using a 10/0 nylon suture. Data collection included anatomic pathology of the lesion and data from ophthalmic examinations at each visit (including epiphora, inferior canalicular irrigation, and fluorescein dye disappearance test [FDDT]), as well as stent extrusion or other complications.<BR><B>RESULTS: </B>No complications were observed during the surgeries. The stents remained in place for an average of 4months, with no extrusions prior to removal. The mean follow-up period was 4.8years (SD=2.0), during which no other complications were noted. Only one patient experienced intermittent epiphora, also present in the fellow eye. At the final visit, FDDT was normal in all eyes, and all patients demonstrated patency of the inferior canaliculus upon irrigation.<BR><B>CONCLUSIONS: </B>Primary reconstruction of an inferior lacrimal drainage duct following tumor resection can be successfully performed, resulting in favorable functional recovery.
