MNP Malleus Nothch Tympanoplasty Prostheses

Concave recess provides additional implant stability when placed under the malleus handle. Head plate is relatively smaller.

Conically shaped bell: optimally adapts to the stapes head encouraging acoustic transfer function in the direction of the oval window. Recessed slots allow adequate space for the stapedius tendon and are easily augmented in case of superstructure anomaly.

Product Information

FOR COUPLING TO THE MALLEUS: REDUCED RISK OF DISLOCATION AND MIGRATION

In ossicle reconstruction the malleus often still exists. Many surgeons want to preserve it and thus ensure stable coupling to the prosthesis. Since the area around the malleus handle usually has the largest tympanic membrane deflection, simultaneous implant/drum contact is beneficial here.

MNP’s concave recess facilitates this contact when placed under the malleus handle providing implant stability. Because of this recess the head plate of the MNP is relatively smaller.

Benefits

Long term experiences
Maximum intraoperative visibility
Improved stability and handling
Fixed length prosthesis family available in 0.25 mm increments. Shortening not necessary.
Excellent biocompatibility
