Droplet Generation During Mastoidectomy and Mitigation by Use of a Novel Barrier Drape.
Article in Cureus, 2025. 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
objectiveThis study aims to investigate the degree of contamination generated by mastoid drilling and the extent to which this is mitigated by the use of a novel barrier drape, Otodome, which contains the surgical field. STUDY
designCortical mastoidectomy with a high-speed self-irrigating drill was performed under three test conditions in the cadaveric lab, including A, without a microscope, B, with a microscope alone and C, with a microscope fitted with the Otodome. Schülke Optics fluorescent solution was used as irrigation fluid.
settingHigh-speed irrigation drills used during mastoidectomy create large amounts of droplet dispersion. This study quantifies the amount of droplet dispersion and the extent to which the barrier drape mitigates it.
methodsThe degree (mild, moderate or severe), distribution, and distance of contamination of the surroundings were collected in each test condition. The extent of contamination of the surgeon was noted.
resultsCondition A had the worst contamination of both the surgeon and surroundings, with the furthest distance and heaviest density of droplet spread after a cortical mastoidectomy. Droplets were dispersed up to 290cm from the surgical field. Using the barrier drape in Condition C significantly reduced the droplet dispersion to a maximum of 78cm from the surgical field. There was a significant reduction in the density of contamination of the surroundings. Most of the heavy contamination was confined within the barrier drape. There was no contamination of the surgeon's face and head region.
conclusionMastoid drilling produces an extensive amount of droplet dispersion. Improvised barrier drapes have been shown to mitigate this problem, but are cumbersome to use. The Otodome is shown to be an effective barrier drape.
