OVAL WINDOW
When there is no stapes super structure, a
Vibroplasty-OW-Coupler can be placed directly
onto the stapes footplate.

HEAD OF THE STAPES
Alternative coupling aids for the FMT
attachment to the head of the stapes are
available in Vibroplasty-CliP-Coupler and
Vibroplasty-Bell-Coupler design.
Advantages:
• Standardized procedure in the oval
window region
• Uses natural pathway of sound
• Available in different sizes
ROUND WINDOW
When the anatomy does not allow for a perpendicular
placement of the FMT to the round window membrane,
a Vibroplasty-RW-Coupler can be used as an
alternative coupling aid.
Advantages:
• More flexibility in Round Window Vibroplasty
• Adapts to fit smaller round window diameters
• Less drilling in many cases
Cartilage to give pre-stress.
