[Recanalization of nasolacrimal duct with radio frequency: preliminary study].
This preliminary clinical series evaluated radiofrequency-assisted recanalization of the nasolacrimal duct in adults with confirmed lower lacrimal system obstruction. The procedure used a monopolar high-frequency device at 450 kHz and 150 W under local anesthesia with sedation. At 90 days postoperatively, 81.25% of patients had successful irrigation indicating duct clearance, while 18.75% had irrigation failure.
Key points
- The study assessed radiofrequency-based recanalization to restore lacrimal flow in nasolacrimal duct obstruction.
- Sixteen eyes of 16 adult patients were treated by the same surgeon using a monopolar device at 450 kHz and 150 W.
- Patients were followed for at least 120 days with clinical assessments including irrigation and symptom checks.
- At 90 days, 13 patients had positive irrigation consistent with duct clearance and 3 had irrigation failure.
- The abstract describes the intervention as effective but does not report a comparator group.
