A model built to a case — the one photographed here has fluid-filled canals and simulated otoliths, so a posterior-canal BPPV attack and the Epley manoeuvre can be watched happening.

Commissions run directly with the maker. Send the anatomy you need shown and the teaching point it has to carry; he answers with a feasibility note, a price and a date.
The example shown is a custom temporal bone and semicircular canal model made to simulate benign paroxysmal positional vertigo: the canals were filled with fluid and otoliths added, so the displacement during a position change — and its repositioning back into the utricle — is visible step by step.
