Surgical anatomy of the labyrinthine artery - a systematic review and meta-analysis.
Synthesis in Neurosurgical review, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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 labyrinthine artery (LA) is usually exposed during surgical approaches to the cerebellopontine angle (CPA). However, the literature lacks a systematic review of its anatomy. Therefore, this study aimed to determine the LA's surgical anatomy, including its morphometry, branches, cranial nerve relationship, and origin. Major databases (PubMed, Embase, Science Direct, Scopus, and Web of Science) were searched systematically until March 2024. A total of 33 studies (n = 3778 arteries) were included. The most prevalent pattern of LA was a single branch, constituting 51% (95% CI: 9.9-56.7; p < 0.001) of the general population. Nevertheless, in the North American and Asian populations, there was a dominance of double branching with a prevalence of 51.3% (95% CI: 2.9-66.1; p < 0.001) and 50.4% (95% CI: 1.4-67.1; p < 0.001), respectively. Regarding the LA relationship with cranial nerves (CN), we found the vessel to be superior to the cochlear nerve in 90.5% (95% CI: 61.3-100.0; p = 0.001), inferior to the vestibular nerve in 89.4% (95% CI: 44.9-100.0; p < 0.001), and inferior to the facial nerve in 88.0% (95% CI: 64.0-100.0; p < 0.001). The most common vessel that the LA originated from was the anterior inferior cerebellar artery (AICA) - 75.4% (95% CI: 62.7-86.4; p < 0.001). However, this was not constant in all populations, as in Colombians, it arose from the BA most frequently at 66.5% (95% CI: 44.6-85.4; p = 0.025). Neurosurgeons must understand the surgical anatomy of the LA. It can provide important topographical information during tumor resection and aneurysm clipping, preventing many complications, including vertigo and hearing loss.
