Why use the OTOSURG simulator

  • To train in otoendoscopy, microscopic ossiculoplasty, and to learn how to handle an endoscope or exoscope in a realistic environment
  • To teach and practice surgical procedures such as ossicular replacement prosthesis placement, without risk to the patient
  • Showcase your medical devices at conferences (with customized models : with / without eardrum, etc.)

Advantages of the OTOSURG simulator

  • Realistic procedure and endoscopic view of the eardrum

  • Scalability of the model according to the learning curve and the audience: different widths of the ear canal, possibility of coloured visual indicators…

  • Repeatability of the procedure for the same group

  • Playful and didactic learning aspect

  • Customised options and adaptability of the model according to needs

The OTOSURG simulator is a model for trans-canal tympanoplasty, ideal for otoendoscopy or microscopic surgery via ear canal. It is designed for surgical training for all procedures in the tympanic cavity.

 

The following structures are represented :

  • Ear canal skin, annulus and tympanic membrane,
  • Anatomical landmarks of the tympanic cavity,
  • Chord of the tympanic membrane, stapes tendon, tensor muscle of the malleus,
  • Mobile ossicular chain.

 

Thanks to its single-use cartridges, it allows various surgical procedures to be performed :

  • Incision and detachment of the skin from the ear canal,
  • Lifting of the eardrum,
  • Exploration of the tympanic cavity,
  • Preservation or disjunction of the ossicles,
  • Ossiculoplasty (PORP / TORP, transposition, piston, etc).

 

The OTOSURG simulator is available in a set consisting of :

  • 1 reusable temporal bone model
  • 1 articulated arm
  • 1 set of single-use cartridges to be selected from various pathologies

 

 

Type of cartridges available* :

  • Normal tympanic cavity (no pathology cartridge)

 

  • Tympanic perforations (possibility to customise the type of perforation – contact us)
    • Posterior perforation
    • Anterior perforation

 

  • Otosclerosis
    • Otosclerosis (normal tympanic cavity with fixed stapes)
    • Otosclerosis after stapedectomy (stapes and plate missing, thin membrane under the oval window)

 

  • Ossiculoplasty
    • Normal cavity, no incus, for PORP placement
    • Normal cavity, no incus, no stapes, mobile plate, for TORP placement

 

  • Chronic otitis (under development)
    • Retraction pocket
    • Cholesteatoma

 

NB1 : other types of cartridge are under development. Please do not hesitate to contact us for further information.

NB2 : each element of the cartridges can be customized on request (specific colour of anatomical elements, with or without eardrum, etc). Please do not hesitate to contact us

 

The following items are also available on demand :

  • Fake liquid blood, to make the simulation environment more realistic
  • Aponeurosis plate (50 x 50 x 0.3mm, 3D printed)
  • Cartilage plate (50 x 50 x 0.9mm, 3D printed)
