A millimetric ruler for Lester Jones tube placement in conjunctivodacryocystorhinostomy.

Vigo RL, Ortiz-Basso T, Vilas MN, Prémoli J - Clin Ophthalmol (2015)

Bottom Line: The success rate was 100%, with an average operating time of 15 minutes.In nine patients, late migration of the Jones tube into the nasal cavity required a secondary intervention, with successful Jones tube repositioning.The millimetric ruler engraved in the sleeve of the trocar allows measuring and placing a personalized tube for each patient.

ABSTRACT

Purpose: To describe the use of a ruler to increase the accuracy and customization of Lester Jones tube placement.

Materials and methods: This was a review of 92 patients who underwent minimally invasive conjunctivodacryocystorhinostomy using this instrument.

Results: The success rate was 100%, with an average operating time of 15 minutes. In nine patients, late migration of the Jones tube into the nasal cavity required a secondary intervention, with successful Jones tube repositioning. In five cases, obstruction of the tube opening was caused by conjunctival overgrowth.

Conclusion: The millimetric ruler engraved in the sleeve of the trocar allows measuring and placing a personalized tube for each patient.

f1-opth-9-1523: Trocar for Jones tube placement, with a millimetric ruler engraved.

Mentions: A video endoscope (Tricam SL; KARL STORZ GmbH and Co KG, Tuttlingen, Germany) was introduced into the middle nasal cavity for visualization and electrocauterization. The inferior third of the caruncle was excised. The trocar (Figure 1) was inserted from the semilunar directed to the middle meatus through the thin lacrimal bone (Figure 2). Once the trocar was in a satisfactory position, the central wire was removed, and the sleeve allowed the direct insertion of a guide rod. Before removing it, the millimetric ruler (Figure 3), which was engraved in the sleeve, was checked. In this way, we were able to find a personalized tube for each patient. After the trocar sleeve was removed, a Pyrex Lester Jones tube was inserted down the guide rod. The proximal end of the tube was secured in position at the medial canthus with a 6.0 nylon suture, which was removed 20 days after the surgery. See the full video of the surgery using the millimetric ruler.
