Bending the rules: A novel approach to laryngeal surgery in a body donor study.
Article in Head & neck, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundTransoral laser microsurgery, the standard surgical approach for early-stage laryngeal cancer, necessitates an unobstructed line of sight to the operating field. However, achieving adequate laryngeal exposure can be challenging, potentially compromising treatment outcomes.
methodsWe developed a 3D-printed curved laryngoscope (sMAC), designed to match the upper airway anatomy. In a user study (n = 15) with a human body donor we compared the sMAC system to conventional microlaryngoscopy regarding laryngeal exposure and accessibility in a difficult exposure scenario.
resultsAll 15 participants achieved complete glottic exposure and successfully manipulated laryngeal landmarks using the sMAC system. Only four participants achieved partial exposure using microlaryngoscopy. Positioning of the sMAC system was significantly faster (p = 0.023). A vocal cord resection was conducted successfully (n = 2) using the sMAC system.
conclusionThe sMAC system effectively addresses challenges associated with transoral laryngeal surgery. Ongoing development aims to overcome current limitations of the system and prepare first clinical trials.
