Epiphora associated with anomalies of the distal end of the nasolacrimal duct in children over 12 months: endoscopic findings and treatment.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeCongenital epiphora can be related to anomalies of the nasolacrimal duct. This study aimed to assess the distal end of the nasolacrimal duct and the outcomes of endoscopic treatment in children older than 12 months with congenital epiphora.
methodsThis retrospective analysis describes the clinical characteristics, management, and outcomes of symptomatic congenital lacrimal obstruction in 32 lacrimal systems of 23 children. Data was collected on the preoperative symptoms, age at the time of surgery, intraoperative findings, treatment modalities, and outcomes of the children in our cohort. All patients underwent a standard endoscopic lacrimal examination, including irrigation and diagnostic probing, viewed via the inferior meatus. Cases with complex anomalies characterized by obstructions in the canaliculi, nasolacrimal junction, or nasolacrimal duct were excluded.
resultsThe mean age at the time of surgery was 48.03 (±27.99) months. Four different types of distal nasolacrimal duct obstruction were diagnosed. These were obstructions by a membrane (n=12), ostium stenosis (n=15), impacted turbinate (n=3), and membranous residual flaps (n=2). They were all managed with inferior meatus microsurgery and nasal endoscopic probing without silicone intubation. After a mean follow-up period of 14.75 (±11.93) months, successful outcomes were achieved in all cases.
conclusionMicrosurgery to the inferior meatus, performed under nasal endoscopy, is a safe and effective treatment for isolated anomalies of the distal end of the nasolacrimal duct in children older than 12 months. We do not recommend silicone intubation in the absence of complex lacrimal system anomalies.
