Motion Analysis of Ear Surgery Training on an Ovine Model.
Article in Cureus, 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
introductionMotion analysis is crucial for surgical training, especially in intricate procedures like ear surgery. Hand movements during myringotomy and stapedectomy training on a sheep's head model were evaluated in this study using accelerometer-based sensors. The aim is to identify specific motion characteristics-including tremor and speed consistency-that distinguish surgical expertise levels and quantify the efficiency gap between trainees and experts. MATERIALS AND
methodsParticipants (n=24) were divided into three groups: residents (n=10), specialists (n=10), and senior surgeons (n=4). Accelerometer sensors captured data on time, path length, acceleration, tremor, and speed consistency. Data analysis utilized the Kruskal-Wallis test followed by Mann-Whitney U post-hoc comparisons with Bonferroni correction to identify specific inter-group differences.
resultsSignificant differences were found across all parameters (p < 0.001). Senior surgeons demonstrated the highest efficiency, performing stapedectomy 70.6% faster than residents and 42.9% faster than specialists. Notable gaps in stability were observed; residents exhibited a 14% lower speed consistency and 66.7% higher tremor levels compared to seniors. Specialists occupied an intermediate phase but still maintained a 42.8% higher tremor rate than senior surgeons, indicating a prolonged refinement period for fine motor control.
conclusionsThe data reveal a clear, quantifiable learning curve. Residents require significantly more time and exhibit less controlled movements, while specialists show technical refinement but have not yet reached the high-level economy of motion seen in seniors. These objective metrics, particularly efficiency gaps and stability consistency, can help tailor training programs to focus on precision and economy of motion.
