Intuitive Controls

With intuitive handling, OTOPLAN puts highly responsive controls right at your fingertips.

Guided Workflow

Step-by-step guidance highlights recommended actions and leads you through the clinical workflow.

Seamless Data Management

Easily access DICOM files directly from USB or external hard drives, or query from your clinic’s PACs network.

Streamlined Clinical Workflows

OTOPLAN utilizes standard radiology imaging, including MRI, CT, and CBCT. With a simple data management interface, OTOPLAN makes it easy to securely access DICOM images directly from USB, external hard drives, or PACs network.

You can integrate OTOPLAN to your PACS, so you can easily query and retrieve the data you’re look for directly from your radiology team. You can also save [.oto] files to securely share OTOPLAN cases.

OTOPLAN is designed for seamless integration into your clinical workflow. By streamlining processes and providing powerful insight into anatomy, OTOPLAN enhances both pre-operative planning and post-operative care.


OTOPLAN gives you incredibly detailed 3D reconstruction of each patient’s anatomy in just seconds. Key anatomical structures—including facial nerve, chorda tympani, sigmoid sinus, and the full cochlea—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, change transparencies—OTOPLAN makes it simple to see incredibly detailed 3D reconstructions.

  • Full 3D cochlea
  • Round window membrane and bony overhang
  • Virtual Trajectory Planning

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 in 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 Thickness Mapping

Find optimal placement for implant or screws by setting a custom threshold and creating a heatmap of bone to see distance to dura or to the air cells.

3D Ruler

Rotate any plane and precisely measure the distance between any two points on 3D structures.

Virtual Trajectory Planning

With OTOPLAN, you can easily visualize how any given surgical trajectory would affect anatomical structures. 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 or for visualizing optimal in-plane angle for electrode insertion into the cochlea. It can also be useful for other otological procedures, such as planning surgical access for middle ear surgery.

Optimal Cochlear View

By freely rotating all imaging planes, OTOPLAN lets you get an ideal oblique view of the cochlea. In this view, you can easily measure cochlear parameters in seconds. OTOPLAN instantly calculates detailed cochlear length and tonotopic frequency. AI assistance combines 3D data with user input to help ensure accurate and consistent measurement of cochlear parameters.

Electrode Visualization Audiogram

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 the anatomical and audiological information in one intuitive view. You can easily add pre-op and post-op audiogram 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.


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 five FLEX arrays available in sizes between 20–31.5 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 fit 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

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 pdf or PowerPoint report of a patient’s data, including post-operative analysis.

Automatic Contact Identification

The latest version of OTOPLAN features a powerful new tool: Automatic Contact Detection. Now, you can quickly identify the real post-operative angular insertion depth and tonotopic location of each individual
electrode contact with just a few clicks. This real electrode location data can be easily exported to MAESTRO software to enable Anatomy-Based Fitting.

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 9.0 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 9.0, you can now quickly assign center frequencies based on the actual anatomical location of each electrode contact.


Next Steps: OTOPLAN

With intuitive controls and a guided workflow, OTOPLAN is simple to use and easy to understand. This means you can already get started with OTOPLAN with just a few hours of hands-on training.
