Osteotomy Techniques in Endoscopic Dacryocystorhinostomy: A Three-Decade Comparative Cohort Study.
Article in Laryngoscope investigative otolaryngology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Endoscopic dacryocystorhinostomy (DCR) is a well-established surgical procedure used to restore lacrimal drainage in patients with nasolacrimal duct obstruction. Various instrumentation techniques have been used for lacrimal bone osteotomy; however, their comparative effectiveness remains debated. This study aimed to evaluate surgical outcomes of endoscopic DCR performed using four different instrumentation techniques. Methods: This retrospective comparative cohort study included 360 consecutive endoscopic DCR procedures performed on 312 adult patients between 1995 and 2024 in a tertiary care center. All surgeries were performed by a single surgeon. Osteotomy was performed using a drill, microdebrider, Kerrison punch, or thulium:YAG laser. Surgical success was defined as resolution of symptoms and confirmation of a patent neo-ostium on follow-up. Comparative statistical analysis was performed to evaluate differences in success rates among techniques. Results: The overall success rate was 95.3%. Success rates were comparable across all instrumentation techniques, with no statistically significant difference observed between groups ( Conclusion: Endoscopic DCR demonstrated high success rates across all instrumentation modalities. Surgical outcome appears to depend more on surgical technique and experience than on the specific instrument used for osteotomy.
