2023年5月7日 · CT. Particularly useful when postoperative radiographs fail to demonstrate the location of the electrode array adequately or if postoperative infection is suspected 1. Usually thin-collimation (≤1 mm) scanning performed contiguously or with a 0.5–1-mm overlap is required.

2020年8月15日 · Pre-operative imaging plays a pivotal role in patient selection for cochlear implant surgery. Key imaging findings on pre-operative scans that may have an impact on the surgical procedure need to be reported.

2023年3月9日 · A cochlear implant is a surgically placed electronic device that directly stimulates the viable spiral ganglion cells of the cochlear nerve, bypassing the damaged organ of Corti hair cells.

Recent advances in CT scanner design and the availability of powerful image processing software have improved the utility of CT scanning for cochlear implant patients. Improvements in spatial resolution now allow identification of electrodes and anatomical detail at the submillimeter level, providing important information for clinical workers.

When a cochlear implant (CI) is in place, CT can be especially difficult because of artifacts from the implant. Furthermore, the absence of standard cochlear turn nomenclature renders radiology reports regarding CI insertion depth difficult to understand.

2015年2月1日 · RESULTS: Thirty-six temporal bones with cochlear implants underwent CT interpretation for implant location. Interobserver agreement was similar when comparing cochlear implant tip location by using a quadrant nomenclature on axial and coronal images and on …

2023年3月9日 · In this article, imaging protocols for sensorineural hearing loss and the normal inner ear anatomy are reviewed, with a brief description of cochlear implant devices and surgical techniques.

2003年9月1日 · Cochlear implantation is often performed as an outpatient procedure and is considered an acceptable treatment for severe to profound sensorineural hearing loss in patients who are refractory to conventional hearing augmentation.

2020年8月15日 · Cochlear implants are increasingly used to treat sensorineural hearing disorders in both children and adults. Pre-operative computed tomography and magnetic resonance imaging play a pivotal role in patient selection, to rule out findings that preclude surgery or identify conditions which may have an …
