LAByrinth

AI-powered temporal bone surgical training — anywhere, anytime.

Structured, case-based dissection practice with automated expert feedback. No dedicated lab required.

The training gap

Temporal bone dissection is the foundation of otologic surgical training. But cadaveric bones are scarce and expensive, dedicated labs are hard to access around clinical duties, and expert feedback is inconsistent. The result: trainees get far fewer drilling hours than they need, often without structured guidance.

How LAByrinth works

Drill anywhere

3D printed temporal bones derived from real CT data, paired with a portable drilling kit. Practice at home, in a call room, or anywhere with a desk — no dedicated lab required.

Case-based curriculum

Every bone tells a clinical story. Progress through a patient narrative with escalating decision points — the same choices you face in the OR. Seven case narratives from cochlear implant to lateral temporal bone resection.

AI-guided feedback

HNLE — our Heuristic Neurotologic Learning Environment — uses computer vision to compare your dissection against expert reference standards. Structured feedback available 24/7, no faculty scheduling required.

What makes HNLE different

1

Identical anatomy comparison

HNLE compares your dissection against expert references filmed on the exact same 3D printed anatomy. Not a generic atlas — a direct comparison of your work against what the same bone should look like when done right.

2

Stage-gated progression

Checkpoints at each surgical stage ensure you demonstrate proficiency before advancing. No more skipping ahead or missing critical steps.

3

Learns from mistakes

HNLE is continuously trained on both expert references and annotated learner errors — violated semicircular canals, thermal injury patterns, inadequate exposure. It knows what "wrong" looks like, not just "right."

4

Clinical context, not just anatomy

Each case presents a patient scenario with surgical decision points. Trainees learn clinical judgment, not just motor skills. “The electrode won’t advance — now what?”
