3D printing promises to correct sunken chest at a high cost

Published on June 09, 2026 | Translated from Spanish

A new surgical technique uses custom prostheses created with 3D printing to correct pectus excavatum, known as sunken chest. It promises to be less invasive and offer faster recovery than traditional methods, although its price in private clinics can reach several thousand euros, leaving it out of public healthcare.

Assisted robotic surgery showing a custom titanium thoracic prosthesis being inserted via 3D printing into a patient's sunken sternum, with robotic arms holding the biomedical piece while a surgical monitor displays the CAD model in real time, LED surgical lights illuminating the scene, sterile operating room background with metal instruments and touch screens, photorealistic technical visualization style with polished metal textures and translucent medical plastic, soft shadows and dramatic contrast, hyperrealistic detail in the artificial ribs and the reticular structure of the prosthesis.

Titanium or PEEK prostheses: technical precision with future risks 🏥

The surgery replaces bone remodeling with the implantation of custom-designed titanium or PEEK pieces using a 3D scanner. By not requiring large incisions or cuts in the sternum, hospital stay is reduced. However, these implants can suffer rejection or shift over time, requiring costly periodic check-ups. The studies supporting the method are funded by printer and prosthesis manufacturers, and its long-term aesthetic effectiveness has not yet been evaluated.

The custom prosthesis: your insurance calls it cosmetic surgery 💸

The patient reads new technique and already imagines themselves operated on, ready to show off their torso at the pool. What they are not told is that their private insurance will likely classify it as cosmetic surgery and won't pay a single euro. So, between the titanium implant and the bank account, the sunken chest can become the least of their problems. At least, there is always the traditional method of acting tough and taking a deep breath.
