Stenvers view Dr Craig Hacking ? and A.Prof Frank Gaillard ? et al. Stenvers view is a oblique radiographic projection used to demonstrate the petrous temporal bone, IAM and bony labyrinth. Fine slice multi-detector CT of the petrous bone has replaced the Stenver view due to far superior anatomic detail. It was also used to assess electrode placement following the insertion of a cochlear implant, but has been succeeded by the modified Stenvers view. The central beam is positioned 45 degrees posteriorly and 12 degrees caudally 1 and performed AP. A similar projection can be obtained on reconstructed CT images, approximated by an oblique coronal projection.... Read more

Cochlear implants (CI) are a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing. Unlike conventional hearing aids, the cochlear implant does not amplify sound, but works by directly stimulating any functioning auditory nerves inside the cochlea with an electric field. External components of the cochlear implant include a microphone, speech processor and an RF transducer or primary headpiece coil. A secondary coil is implanted beneath the skull' s skin and inductively coupled to the primary headpiece coil. The implant gives recipients additional auditory information, which may include sound discrimination fine enough to understand speech in quiet environments. Post-implantation rehabilitative therapy is often critical to ensuring successful outcomes. Radiographic evaluation Plain film Post operative plain film radiography of the temporal bones are sufficient in a majority of patients. Plain radiography is the most helpful modality to assess for extrusion and superior in assessing the number of inserted electrodes. Typically a modified Stenvers view is performed, which has succeeded the original Stenvers view. CT Particularly useful when postoperative radiographs fail to demonstrate the location of the electrode array adequately or if postoperative infection is suspected... Read more
