Abstract Purpose: To report effectiveness of 16 gauge sheath for treatment of dacryolith in the lacrimal sac.

Case: A 62-year-old male with epiphora and discharge of the right eye was referred to us. Forced irrigation test showed passage of the fluid into the nose and backflow of putrid mass. We suspected nasolacrimal duct stenosis and scheduled sheath guided intubation. Intraoperatively, we found a large dacryolith in the lacrimal sac. The hard large dacryolith made it difficult to discharge the dacryolith into the inferior nasal meatus using 18 G sheath. However, 16 G sheath could effectively discharge the dacryolith, which was 11 mm in the longitudinal diameter.

Conclusion: Sixteen G sheath is large enough in size and is able to push a material strongly into the inferior nasal meatus, and therefore it can discharge a large dacryolith.
