Engineered in India.
Built for every operating room.
OSSA+ exists because surgical skill should be limited by dedication, not by access to practice material.
From one question at the drilling bench.
Why does a trainee's first real mastoid surgery happen on a patient — or, if they're lucky, on one precious cadaver bone a year? Every alternative we found was either too crude to teach real judgement, or too expensive to practise on more than once.
So we built the material first. OSSA+ Composite™ took years of mixing, casting and listening to surgeons before the first model ever shipped. Then we built models for the whole of ENT — not just the ear — and connected everything to KnowledgeBridge, so a model never arrives without a course to go with it.
Today our models are drilled at workshops, departments and conferences across India and beyond — and our balloon trainers are still the only ones of their kind anywhere in the world.
What we believe
- Repetition is a right of training, not a privilege of budget
- Fidelity is measured under the burr, not in a render
- Models without curricula are furniture
- Evidence beats adjectives
What happens in-house
Material R&D
We invent and refine the recipes — bone that drills true, soft tissue that behaves.
Anatomy engineering
Real scans become teachable models — shaped and checked by surgeons at every step.
Casting & finishing
Every model is cast, cured and finished by hand in our own facility — nothing outsourced.
Education delivery
Courses, workshops and certificates — delivered with our partners at KnowledgeBridge International.
Questions we hear at every workshop
