Neuro-Otological Manifestations in Patients with a Hemifacial Port-Wine Stain: A Report of 2 Cases.
Article in The journal of international advanced otology, 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
A port-wine stain (PWS) or nevus flammeus is a congenital capillary malformation that often affects the skin of the head and neck region. Little is known about neuro-otological manifestations associated with this birthmark. We describe 2 patients with a hemifacial PWS and sensorineural hearing loss, caused by involvement of the internal auditory canal (IAC) and inner ear structures. Case one had a history of sudden vestibular hypofunction, followed by high-frequency sensorineural hearing loss 2 years later. In the second case, the exact onset of the high-frequency hearing loss could not be determined. In both patients, magnetic resonance imaging (MRI) showed dural enhancement of the IAC and a loss of T2 signal intensity of the ipsilateral labyrinth. This report shows that a PWS of the head and neck region may be associated with dural thickening within the IAC and secondary inner ear dysfunction. In patients with this capillary malformation suffering from hearing impairment or balance problems, MRI is warranted to detect involvement of the ipsilateral dura and labyrinth.
