OTOPLAN Software

Streamlined, Individualized Otological Surgery

With robust and accurate performance, OTOPLAN* has been developed in close collaboration between CASCINATION AG and MED-EL to unlock the full potential of individualized implantation. OTOPLAN’s unparalleled patient-specific 3D visualizations and measurement data at your fingertips will give you the power to efficiently perform individualized otological procedures with precision.

OTOPLAN also features automatic pre-op cochlear parameter measurements and electrode visualization, post-op implant detection, and allows you to leverage the future of fitting: anatomy-based fitting.

Electrode Visualization

Unique Combined View of Anatomical and Audiological Info

OTOPLAN gives you the power to take cochlear implant surgical planning to a whole new level. With the enhanced electrode visualization tool, you can combine anatomical and audiological information in one intuitive view. You can easily add pre-op data to a patient record and select desired cross-over frequencies for patients with residual hearing.

Even better, with OTOPLAN you can easily visualize how each electrode can fit each individual cochlea. Compare different electrode arrays and see detailed data for each individual electrode contact, including predicted angular insertion depth and tonotopic center frequency.

Electrode Visualization

Individualized Electrode Arrays

When it comes to electrode arrays, one size doesn’t fit all. In fact, there’s a wider range of variation in cochlear duct lengths than shoe sizes. That’s why we designed our FLEX Series arrays to provide the optimal length for the full range of cochlear anatomies.

With six FLEX arrays available in sizes between 20–34 mm, you can achieve complete cochlear coverage and full electrode insertion for each patient. And with OTOPLAN, you can easily see how each one of these electrodes fits inside the individual cochlea with respect to depth and covered frequency.

This is a huge advantage that we can individualize the choice of these electrode lengths. We know there’s a huge variation in sizes from cochlear lengths. The organ of Corti, the cochlear duct length varies from 25– 36 millimeters, really this is a 50% change, from one patient to another patient. —Prof. Paul van de Heyning

OTOPLAN gives you incredibly detailed 3D reconstructions of each patient’s anatomy in just seconds. Key anatomical structures—including the facial nerve, chorda tympani, sigmoid sinus, and the complete inner ear—are highlighted both in 3D and in each imaging plane.

Think of the possibilities: You can easily navigate through the temporal bone, chorda tympani, and facial nerve. Rotate 360° in any direction, zoom, or change transparencies. OTOPLAN makes it simple to see incredibly detailed 3D reconstructions.

  • Automatic 3D inner ear
  • Virtual trajectory planning
  • Image fusion

Unparalleled Visualization

Instantly and seamlessly rotate and navigate through coronal, sagittal, and transverse anatomical planes to get an optimal 2D and 3D view of any anatomical structure in seconds.

3D Cochlea Reconstruction

Explore each individual cochlea via a detailed 3D reconstruction. This powerful tool can be especially helpful for assessing cochlear malformations. You can also export the model as an stl. file for 3D printing.

Bone and Skin Thickness Mapping

Perform automatic 3D reconstruction and thickness measurements of the skin and bone. Set a custom threshold and create a heatmap of skin or bone to see the distance to the dura or to air cells.

Virtual Trajectory Planning

You simply set the target point and then pivot the trajectory in any direction. This can be helpful for planning individualized surgical access to the cochlea for each patient.

3D Virtual Electrode Insertion

With a simulated 3D view of the electrode insertion into the cochlea and corresponding insertion depth and frequency, you get more 3D information about the frequencies covered along the length of the cochlea when selecting the best electrode for each patient. You can also visualize the optimal angle for electrode insertion into the cochlea.

OTOPLAN Software

Post-Op Analysis

OTOPLAN enhances the entire clinical workflow, including post-operative analysis and reporting. With post-operative imaging, you can easily confirm electrode insertion status and automatically generate detailed patient reports. OTOPLAN lets you automatically generate a report of a patient’s data, including post-operative analysis.

The newest version of OTOPLAN has expanded automatic detection beyond electrode contacts to also include the electrode lead and implant housing. It provides visual feedback on the insertion status and lead management.

OTOPLAN also allows you to quickly identify the real post-operative angular insertion depth and tonotopic location of each individual electrode contact with just a few clicks. This real location data can be easily exported to our MAESTRO software for anatomy-based fitting.

OTOPLAN Software

Image Fusion

The newest version of OTOPLAN even allows image fusion so you can get a view of the best information in each image modality (CT and MRI) combined. You can automatically fuse the pre-op cochlear parameter measurements to the post-op image for a faster and more consistent post-op analysis.

Anatomy Based Fitting

Our philosophy has always been to provide a closer match to natural hearing. Our unique full-length electrode arrays help enable more accurate pitch-place stimulation of the natural tonotopic map of the cochlea. Our unique FineHearing sound coding is designed to mimic natural rate coding in the second turn of the cochlea.

Now, with OTOPLAN and our MAESTRO fitting software, we are excited to be reaching closer to natural hearing than ever before with cochlear implants. Our default FineHearing frequency allocation is designed to follow the natural tonotopic map of the cochlea. However, we know that one size does not fit all. This is why we are always striving to provide a closer match for each individual patient.

With our new anatomy-based fitting tools, you can easily fine-tune the frequency map to be closer to the natural map for each individual cochlea. By combining detailed imaging data from OTOPLAN with MAESTRO, you can now quickly assign center frequencies based on the actual anatomical location of each electrode contact.
