Glossopharyngeal neuralgia and hypoglossal nerve palsy: A singular clinical case of two rare concomitant neurovascular conflicts.

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
Background: Neurovascular conflict (NVC) is described as a pathological contact between cranial nerves and vessels. Glossopharyngeal neuralgia (GPN) and hypoglossal nerve palsy (HNP) due to NVC represent rare clinical entities. To our knowledge, we present the first reported case of concomitant GPN and HNP caused by vertebral artery (VA)-posterior inferior cerebellar artery (PICA) complex compression. Case Description: We report an extremely rare case of a 52-year-old man with combined unilateral left-sided GPN and HNP because of NVC involving both the VA and the PICA, successfully treated with a retrosigmoid approach for microvascular decompression (MVD). Postoperatively, the patient immediately recovered without new-onset dysfunction of lower cranial nerves, and a complete remission of symptoms was achieved. Conclusion: As far as we know, in this article, we present the first singular case in the literature of concomitant classical GPN and HNP due to NVC involving both the VA and the PICA. Despite the low incidence of GPN and HNP, clinical picture and intraoperative findings represent clear and reliable elements for their diagnosis. MVD is a successful therapeutic strategy that offers a long-term cure for GPN and HNP.
