Preoperative planning –
making results predictable with simulation

One risk of forced palatal expansion (RPE) is that the face may be asymmetrically widened by the distractor. Simulation-based optimization can support the surgical incision to reduce the risk of asymmetric opening.

“Thanks to the joint fast and successful rollout with Simq, we are able to integrate another product, Simq RPE, and make it available to our partners and customers via the IPS Case Designer.”

Symmetry through optimized cutting

About the customer

KLS Martin Group – “Surgical Innovation is our Passion”

The KLS Martin Group is an internationally active group of companies for innovative medical technology in almost all areas of surgery. With their innovative medical technology solutions such as implant systems, high-frequency surgical devices, surgical lasers, sterilization containers, surgical lights, surgical instruments as well as individual OR solutions, they have set new standards many times.

The task

One risk of forced palatal expansion is that the upper jaw is expanded unevenly by the expansion device, the distractor, in over 55% of cases. Thus, after the treatment, in 25% of the cases the patient even has a strongly asymmetrical face (more than 5 mm asymmetry). By means of patient-specific simulative surgical planning, suggestions for osteotomy guidance and a suitable drill and marking guide have to be made in order to guarantee a symmetrical facial shape after treatment.

The solution

The surgical procedure is individually simulated, optimized, and digitally documented for each
patient.
Based on the existing patient scan, a three-dimensional model is generated for the simulation and the individual osteotomies are predefined.
The patient-specific numerical simulation is the core of the procedure. Here, the optimum symmetry is calculated based on the anatomy with different cutting lengths. The subsequent additively manufactured drill and marking guide transfers the planning to the operating room and serves as a template for the ideal osteotomies and the use of the distractor.

The result

Simq’s patented simulation-based planning of the surgical expansion of the maxilla allows
the procedure to be specifically optimized, the trauma to be minimized and the risk of an asymmetrical opening of the maxilla to be virtually reduced.

With the state-of-the-art, patient-specific procedure, the risk during surgery as well as of postoperative treatments can be brought to a minimum.
