3D Ear Simulator Trains Surgeons Without Using Patients

Published on June 03, 2026 | Translated from Spanish

A French team has developed Otosurg, a surgical ear simulator manufactured with 3D printing. This device allows surgeons to practice endoscopic surgeries with different levels of difficulty and specific pathologies. Unlike cadavers or virtual reality, it offers a realistic and reusable physical replica, resulting in safer and more effective training for future specialists.

3D Printing for More Realistic Surgical Training 🎯

The model accurately replicates the structures of the human ear, including ossicles and nerves. Surgeons can practice complex maneuvers, such as tympanoplasty or implant placement, with a tactile sensation that virtual reality does not provide. Additionally, being a physical object, it avoids the ethical and availability issues associated with using cadavers. The system allows for modifying difficulty and pathologies, offering adaptable training for each level of experience.

Goodbye to Cadavers: The Plastic Ear Arrives in the Virtual Operating Room 😂

Cadavers have always been surgeons' favorite practice companions, but they have two problems: they smell bad and cannot be reused to repeat the same operation twenty times. With Otosurg, residents will no longer have to fight over the only available temporal bone. That said, they haven't yet confirmed whether the model comes with an instruction manual or if they'll have to assemble it like a piece of Swedish furniture.
