Abstract
Objective: To describe a series of six cochlear implant (CI) patients with an extraordinary peak in transimpedances.
Study design: Retrospective case series.
Setting: Tertiary referral center.
Participants: Six adult CI patients who underwent transimpedance measurements and postoperative imaging.
Main outcome measure: Intra- and postoperative transimpedance measurements and a visual inspection of transimpedance matrices (TIMs). The position of electrodes was radiologically identified.
Results: From six patients with TIMs showing an extraordinary peak in the off-diagonal area, five C electrode arrays showed no correct scalar localization in the scala tympani, and one had a correct scalar localization in the scala tympani.
Conclusions: A peaking transimpedance might be a marker for scalar dislocation in CIs.
研究目的研究设计：回顾性病例系列：回顾性病例系列：研究地点：三级转诊中心：主要结果测量：术中和术后跨阻抗测量以及跨阻抗矩阵（TIM）的目视检查。通过放射学检查确定电极位置：结果：六名患者的跨阻抗矩阵（TIMs）在对角线外区域显示出异常峰值，其中五个 C 电极阵列在鼓室没有正确的标度定位，一个在鼓室有正确的标度定位：结论：峰值跨阻抗可能是 CIs 标度错位的标志。
期刊介绍：
''Audiology and Neurotology'' provides a forum for the publication of the most-advanced and rigorous scientific research related to the basic science and clinical aspects of the auditory and vestibular system and diseases of the ear. This journal seeks submission of cutting edge research opening up new and innovative fields of study that may improve our understanding and treatment of patients with disorders of the auditory and vestibular systems, their central connections and their perception in the central nervous system. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines.
