Abstract
The purpose of this review is to present essential imaging aspects in patients who are candidates for a possible cochlear implant as well as in postsurgical follow-up. Imaging plays a major role in providing information on preinterventional topography, variations and possible infections. Preoperative imaging using DVT, CT, MRI or CT and MRI together is essential for candidate selection, planning of surgical approach and exclusion of contraindications like the complete absence of the cochlea or cochlear nerve, or infection. Relative contraindications are variations of the cochlea and vestibulum. Intraoperative imaging can be performed by fluoroscopy, mobile radiography or DVT. Postoperative imaging is regularly performed by conventional X-ray, DVT, or CT. In summary, radiological imaging has its essential role in the pre- and post-interventional period for patients who are candidates for cochlear implants.
Key Points:
• Intraoperative imaging: radiography, DVT
• Preoperative imaging: DVT, CT, MRI
• Postoperative imaging: X-ray, DVT, CT

Zusammenfassung
Ziel dieser Übersichtsarbeit ist die Präsentation von bildgebenden Aspekten bei Patienten, die für eine mögliche Cochlea-Implantation infrage kommen sowie bei postchirurgischem Follow-up. Die Bildgebung spielt eine wichtige Rolle bezüglich der Informationen zu präinterventioneller Topografie, Variationen und möglichen Infektionen. Präoperative Bildgebung mittels DVT, CT, MRT oder CT und MRT zusammen ist notwendig für die Selektion der Patienten, für die Planung des chirurgischen Vorgehens und das Ausschließen von Kontraindikationen, wie z. B. das völlige Fehlen von Cochlea und dem Cochleanerv, oder Infektionen. Relative Kontraindikationen sind Variationen von Cochlea und Vestibulum. Intraoperative Bildgebung kann mittels Fluoroskopie, mobiler Radiografie oder DVT durchgeführt werden. Postoperative Bildgebung wird normalerweise mittels konventionellem Röntgen, DVT oder CT durchgeführt. Zusammenfassend spielt die radiologische Bildgebung eine wichtige Rolle in der prä- und postinterventionellen Phase bei Patienten, die für ein Cochlea-Implantat infrage kommen.
Kernaussagen:
• Intraoperatives Imaging: Röntgen, DVT
• Präoperatives Imaging: DVT, CT, MRT
• Postoperatives Imaging: X-Ray, DVT, CT
