Endoscopic training simulator OTOSURG

trainingfor demonstrationfor healthcare training

Product overview
The OTOSURG simulator is a transcanal tympanoplasty training model designed for hands-on practice in endoscopic and microscopic ear surgery via the external auditory canal. It reproduces tympanic cavity anatomy and provides a realistic endoscopic view of the tympanic membrane for procedural training.

Validated study
Validation study: Validation of a 3D-printed multimaterial transcanal tympanoplasty simulator for endoscopic ear surgery (Otol Neurotol).

Primary uses

• Training in otoendoscopy and microscopic ossiculoplasty techniques.
• Learning endoscope and exoscope handling in an anatomically realistic environment.
• Teaching and practicing ossicular replacement and related procedures without patient risk.
• Demonstration of medical devices and tailored scenarios at congresses or training sessions (customized cartridges, presence/absence of eardrum, coloured markers).

Advantages

• Accurate endoscopic visualization of the tympanic membrane and tympanic cavity landmarks.
• Configurable difficulty and anatomy (different canal diameters, visual indicators) to match trainee level.
• Repeatable scenarios for standardised skills assessment.
• Educational design facilitating stepwise learning and group training.
• Customisation options to suit specific teaching objectives or device demonstrations.

Structures represented

• Ear canal skin, annulus and tympanic membrane.
• Bony anatomical landmarks of the tympanic cavity.
• Tympanic membrane chord, stapedial tendon, tensor tympani attachments.
• Mobile ossicular chain (malleus, incus, stapes) with configurable integrity.

Surgical procedures supported (via single-use cartridges)

• Incision and elevation of canal skin.
• Tympanic membrane lifting and graft placement practice.
• Exploration and manipulation of tympanic cavity structures.
• Preservation, mobilisation or disarticulation of ossicles.
• Ossiculoplasty techniques (PORP, TORP, transposition, piston placement).

Set composition

• 1 reusable temporal bone model (anatomical base).
• 1 articulated arm for positioning.
• 1 selectable set of single-use pathology cartridges.

Types of cartridges available

• Normal tympanic cavity (no pathology cartridge).
• Tympanic perforation cartridges (posterior, anterior and other customizable perforation types).
• Otospongiosis variants (fixed stapes configuration; post‑stapedectomy with absent stapes and residual footplate).
• Ossiculoplasty variants (missing incus for PORP; missing incus and stapes for TORP scenarios).
• Chronic otitis-related cartridges under development (retraction pocket, cholesteatoma simulation).

Additional items available on demand

• Simulated liquid blood to increase realism.
• 3D‑printed aponeurosis plate (50 x 50 x 0.3 mm).
• 3D‑printed cartilage plate (50 x 50 x 0.9 mm).
