From: Nasolacrimal intubation in transcanalicular endoscopic dacryoplasty: a long-term follow-up study

Recurrence rates after transcanalicular microdrill dacryoplasty (tMDP) of our study group by duration of silicone tube intubation in months (m). (a) Distribution of recurrence in patients with an intubation duration of < 3 and ≥ 3 months. (b) Distribution of recurrence in patients with an intubation duration from 3 to < 6 and ≥ 6 months. *p < 0.05.
