Novel 3D-printed aids for total ear reconstruction.
Article in 3D printing in medicine, 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
backgroundTotal ear reconstruction in patients with microtia remains a complex aesthetic and technical challenge. Accurate positioning and customization of porous polyethylene implants are critical, yet current methods often rely on manual planning and intraoperative adjustments.
methodsAt Schneider Children's Medical Center, high-resolution 3D facial scans or CT data were used to design patient-specific preoperative jigs and a custom single-piece implant. The jig guided precise ear positioning using facial landmarks and incorporated vascular mapping via CTA to identify branches of the superficial temporal artery. BioMed Elastic 50A Resin was used for jig printing, and the implant was tailored to patient age and anticipated ear growth.
resultsThe technique enabled accurate ear alignment with the contralateral ear, minimized intraoperative adjustments, and eliminated the need for implant assembly. The integration of vascular mapping into the jig improved flap design and may reduce complications. Compared to traditional methods, this 3D-guided approach demonstrated improved positioning accuracy, reduced operative time, and enhanced aesthetic predictability.
conclusionsThis 3D-guided technique streamlines ear reconstruction and offers an efficient and reproducible solution that improves surgical planning and outcomes in patients with microtia.
