[Technique for jones tube placement in lacimal drainage surgery]

In certain cases, the use of a Jones Tube is necessary for lacrimal duct reconstruction. Although the principle is straight forward, the practical procedure can prove to be difficult. The procedure requires the resection of the medial bony wall of the lacrimal sac. We form a duct between the medial canthus and the nasal cavity using a 14 gauge canula. By removing the needle, the catheter remains in place and serves as a guide for the placement of the Jones Tube with the assistance of an obturator. Thus the duct is not lost and an additional puncture is unnecessary.
