Photon-counting CT demonstration of acute labyrinthine ischemia in idiopathic sudden sensorineural hearing loss: a case report.
Article in Frontiers in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The pathophysiology of idiopathic sudden sensorineural hearing loss (ISSNHL) remains unclear. It is widely hypothesized that vascular ischemia, leading to acute labyrinthine ischemia, may represent the most probable underlying etiology. We describe a 51-year-old previously healthy man presenting with acute-onset left-sided hearing loss, tinnitus, and vertigo persisting for 24 h. His clinical features were consistent with acute labyrinthine ischemia, suggesting this as the probable etiology of ISSNHL. Initial photon-counting CT (PCCT) of the inner ear suggested that the branches of the anterior inferior cerebellar artery (AICA) supplying the inner ear, including the labyrinthine artery, were slightly attenuated and exhibited a sparse branching pattern. Follow-up imaging after therapy within a week revealed significant improvement in both the vascular caliber and blood flow. To our knowledge, this case represents the first successful application of PCCT to directly suggest acute labyrinthine ischemia, providing the first reported radiological evidence for this mechanism.
