One Stage (for Cranial Reconstruction implants)

With One Stage (also referred to as single-stage), you opt for a procedure in which resection and reconstruction take place within a single operation. This can offer advantages for both the surgery and the patient. Thorough preparation is essential.

With the aid of CT imaging, digital 3D models, 3D printing and virtual surgical planning, this procedure can be prepared accurately in advance. At Xilloc, we bring all of these steps together and ensure that you have everything required to carry out a One Stage procedure in a controlled and efficient manner.

When resection and immediate reconstruction come together in a single procedure

One Stage as the best solution

This approach is used when it is desirable to remove the tumour and reconstruct the cranial defect within a single procedure.

For example, in cases of intraosseous meningioma, where resection with wide margins is required and immediate reconstruction contributes to a good functional and cosmetic outcome.

From virtual planning to controlled placement in theatre

Fully prepared, carried out with control

Virtual planning

The resection is determined digitally in advance on the basis of CT data and a 3D model of the skull, supplemented with MRI images where possible. Using the surgeon’s input, this is developed into a design that aligns precisely with the procedure.

Surgical cutting guide

To transfer the virtual planning accurately to the operating theatre, we design and 3D-print a patient-specific cutting guide. This fits precisely on the skull (and, where applicable, the orbit) and indicates the contours of the resection area. The cutting guide is tailored to the instruments you use, such as a craniotome or piezoelectric saw, and can be fixed in the correct position.

Osteotomy and defect

Using the cutting guide, the resection is carried out in a controlled manner according to the predetermined plan. This creates a defect that corresponds exactly to the preparation.

Patient-specific implant

In parallel with the planning, an implant is designed on the basis of the healthy anatomy. Because the shape and size of the defect are known in advance, the implant fits directly onto the created defect.

Implant fixation and placement

The implant can be positioned and fixed in a controlled manner. If required, important information, such as underlying anatomical structures, can be displayed visually on the cutting guide. The planning can also be combined with navigation systems in the operating theatre.
