Prevalence of Cochlear-Facial Nerve Dehiscence and Facial Nerve Stimulation for Adult Cochlear Implant Recipients.

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
Objectives: To estimate the prevalence of cochlear-facial nerve dehiscence (CFD) in cochlear implant (CI) recipients, measure cochlear-facial nerve partition width (CFPW), and analyze the relationship of CFD and CFPW for the presence or absence of facial nerve stimulation (FNS). Methods: A retrospective review of 314 ears from 294 adult CI recipients was conducted. Two blinded reviewers measured CFPW and identified cases with CFD from the preoperative or postoperative high-resolution computed tomography (CT) scan. Analyses included the associations of CFPW and CFD with FNS, defined as facial movement elicited by CI stimulation. Audiologic and surgical data were reviewed for electrode characteristics and management of FNS. Results: Reviewers had excellent inter-rater reliability for CFPW measurements (intraclass correlation coefficient = 0.974). CFPWs were significantly smaller in ears with FNS (median: 0.40 mm) compared to those without FNS (median: 0.48 mm; Conclusion: CFD is a risk factor of FNS in CI recipients. Preoperative high-resolution CT can identify patients with CFD that are at high risk for FNS; however, use of a precurved electrode array may not reduce the risk for FNS in this population. Investigation is needed of interventions to mitigate FNS risk in patients with CFD. Level of Evidence: 3.
