Scopis Tracing Trajects helps you to set the optimal entry point for cranial procedures!

Developed with Dr. Ulrich Thomale, Berlin

Setting the Symmetry Plane and Nasion

Define a symmetry plane and the nasion in any radiological data.

Optimal Trajectory Planning

Align trajectory along intraventricular landmarks.

Anatomical Elongation of Trajectory towards Skin Surface

The trajectory is automatically elongated towards the convexity.

Anatomical Calculation of Mean Trajectory

If two targets must be reached, one joint entry point can be computed automatically.

Taking Measures to the Operation Room

STT computes exact coordinates relative to nasion and midline to find your entry point.

For Guided Interventions with the Ventricle Catheter Guide

Determine correct angulation towards coronal skull surface.

Transfer Complex Planning Data to Surgical Navigation System

Utilize your pre-operative plan to perform surgery with precision, state of the art approaches, and for optimal results.

Every Single Trajectory Needs a Dedicated Planning

Tracing Trajects planning helps to define the most suitable entry point
for neuroendoscopic interventions. The right localization for the necessary borehole trepanation is crucial to perform a straightforward insertion of the endoscope.
Current data showing that for each case an individual planning is inevitable, also for standardized operations such as ETVs.

Scopis Tracing Trajects offers the individual planning of trajectories and calculates the corresponding entry point in relation to the nasion and midline. Moreover, it delivers the central line resulting from two trajectories in order to define the best entry point enabling access to two separate targets. For example, combined Cyst Fenestration and biopsy in the posterior region of the third ventricle.

Scopis Tracing Trajects for Training, Education and Performing in Surgery

The awareness, that planning of endoscopic interventions is essential,
became inherent part in neuroendoscopic training courses. STT helps to get a better understanding by visualizing the real dimensions, potential obstacles and opportunities to achieve surgical goals.

Scopis Tracing Trajecs got used in recent courses during common case evaluations. In interactive workshops the virtual planning of the right entry point can be ideally conveyed by aid of Scopis Tracing Trajects. The planning data can be easily used by transfer to the Navigation System in the OR.

How does Scopis Tracing Trajects work?

Performing endoscopic procedures presupposes the definition of the optimal entry points for the necessary burr hole trepanation. Recent experiences show that even for standardized interventions "Kocher's point" can not be used in most of the cases.

As a result of the large range of variation for the planning of the trajectory, for example in ETV (Endoscopic Ventriculocisternostomy) through the Foramen Monroi to the bottom of the 3rd ventricle, an individual planning is imperative.

Scopis Tracing Trajects is a new tool that facilitates the preoperative planning of ventricular interventions.

In a few steps, the software calculates all the necessary coordinates for the borehole manipulation based on a 3D data set. The user is requested only to plan the nasion as well as the trajectory in the virtual 3D model. As a result of this planning, the software fully calculates the coordinates for the entry point of the frontal  burr hole: Distance from the nasion, distance from the midline and trajectory length.

Scopis Tracing Trajects also helps in planning complex endoscopic procedures. This applies in particular to the question whether a single entry point (burr hole) makes it possible to reach different anatomical spaces with the endoscope and display them with the camera.

Therefore, the software automatically calculates the bisector (mean trajectory) as a result of two single trajectories. This serves as the optimal trajectory to get access to every target through only one burr hole.

“The Scopis® Building Blocks application is an intuitive way for reviewing the complex anatomy of the frontal recess.  Through this app, less experienced trainees can learn to apply ‘book knowledge’ more easily.  In addition, experienced surgeons can more easily identify the critical relationships of the various cells populating the frontal recess; such knowledge is important for effective, safe and efficient endoscopic sinus surgery.“

Prof. Jin Keat Siow, MD

“Frontal recess anatomy at first glance appears complex. The Scopis® Building Blocks software allows frontal recess cells, even diseased ones, to be tagged so that their relationships become immediately evident, resulting in the intuitive emergence of the natural frontal sinus drainage pathway for precise mucosa preserving surgical clearance. A complex anatomical challenge of decades has been simplified for practical surgical planning of today.“

Prof. Oliver Kaschke, MD

“The Scopis® Building Blocks software is a real breakthrough for rhinosurgeons to visualize the individual anatomy of the frontal sinus drainage pathway anterior ethmoid in their complexity. It also helps to teach the younger generation of sinus surgeons. The learning curve to understand and perform frontal sinus surgery will be very much supported by Scopis© Building Blocks.“

Prof. Brend A. Senior, MD
Chapel Hill, NC

“The frontal recess remains the most challenging area for safe and thorough surgery for the Rhinologist.  Scopis Building Blocks is a powerful tool providing a three dimensional understanding of this anatomy that is useful for the novice as well as the seasoned surgeon.  I look forward to utilizing it for my residents and students.“

Claudio Callejas, MD
Pontifical Catholic University
of Chile (UC)

“Since we had the opportunity to observe the delegates at the course using the Scopis® Building Blocks software, we realized of what a great tool it is to understand the complex anatomy of the frontal recess. Scopis® Building Blocks has the potential to become the standard in the frontal sinus surgery planning. Utilizing this innovation demonstrates the world class status of the Pontifical Catholic University of Chile also in the medical field.“

Prof. Rainer Weber, MD

“The complex anatomy of the anterior ethmoid and the frontal sinus drainage pathway makes surgery of the frontal sinus most challenging. I like Scopis® Building Blocks as a very valuable tool to get a three-dimensional understanding of this anatomy before starting the operation.  It is now integral part for the education of younger colleagues and for lectures and operation courses on endoscopic frontal sinus surgery.“

Ping-Hung Shen, MD
Taichung City, Taiwan
Republic of China

“Almost every resident in endoscopic sinus surgery training have struggled on frontal sinus surgery. The Scopis Building Blocks Planning software, which based on famous “building blocks concept” by Prof. PJ Wormald, can remarkably speed the learning curve of frontal sinus surgery. This software is expected to be of great value in preoperative planning and teaching in terms of endoscopic frontal sinus surgery.“

Courses & Events on Tracing Trajects planning

In the Training Course STT, the practical use of a new software tool for planning intraventricular procedures and shunt systems is taught and practiced.  
A test version of the STT software will be provided to the participants for download to a local computer about 4 weeks before the Training Course. In a tutorial the use of the software is explained by means of an example. Afterwards, the user can download various test data records and plan these cases independently.
During the workshop, Dr. Thomale will explain the planning again by means of a further example. Subsequently, the participants can ask questions in the direct dialogue and get help from experts.
