Increasing stability of total ossicular replacement prosthesis
Russian Otorhinolaryngology, 2023When performing tympanoplasty, one of the key stages is ossiculoplasty – reconstruction of the chain of auditory ossicles through prosthetics. When the chain of auditory ossicles, including the superstructure of the stapes, is destroyed, complete ossicular prostheses are used.

PlastiporeTM total ossicular replacement prosthesis
The Laryngoscope, 1976AbstractIn those ears in which the incus and/or malleus are missing or not suitable, a columella made of high density polyethylene sponge has proven to be very effective. Tissue readily grows into the large pores of this material so that it is well tolerated in the body.

Experience With a Polyethylene Total Ossicular Replacement Prosthesis
Archives of Otolaryngology - Head and Neck Surgery, 1979Surgical reconstruction of ossicular defects in chronic middle ear disease is a difficult problem. We have reviewed our results with the use of the Plastipore total ossicular replacement prosthesis (TORP). Of 29 procedures that were analyzed, nine were considered successful.

Ossicular Replacement Prostheses
2004The field of biomaterials has, to a large extent, derived most of its common materials from other fields of materials science. Similarly, biomaterials in otolaryngology have been previously utilized in other biomedical arenas. As with most implants, homografts or autografts are generally considered the ‘gold standard’ against which all other materials ...

Hearing results with the titanium ossicular replacement prostheses
European Archives of Oto-Rhino-Laryngology, 2005The purpose was to study the hearing results in patients receiving a Kurz titanium Bell partial ossicular replacement prosthesis (PORP) or an Aerial total ossicular replacement prosthesis (TORP). The study was a retrospective chart review in a tertiary otologic referral center.

Middle-ear dynamics before and after ossicular replacement
Journal of Biomechanics, 2000The mechanism of hearing involves conduction of mechanical vibrations along the ossicular chain to the inner ear. An acoustic wave is collected and transformed as it passes down the ear canal and impacts on the tympanic membrane (ear drum). The drum is connected to the inner-ear by three ossicle bones (malleus, incus, and stapes) in a complex ...

Total and partial ossicular replacement prostheses in children
Otolaryngology–Head and Neck Surgery, 1994Although ossicular reconstruction in children may carry a risk of failure because of recurrent middle ear disease, the procedure offers the potential for restoring binaural hearing during the school years when it is so critical. Of a series of 45 reconstructions with total and partial ossicular replacement prostheses, 6 were extruded for a surgical ...

TOTAL OSSICULAR REPLACEMENT PROSTHESES: MATERIALS AND DESIGNS
Nano LIFE, 2010Surgeons and patients are demanding improved replacements for dysfunctional ossicular bones. Replacement of the entire ossicular chain and positioning the prosthesis between the stapes footplate and the tympanic membrane are of particular challenges. Many materials have been used since the first ossicular replacement; at the present time, the two most ...

Hearing Results With the Dornhoffer Ossicular Replacement Prostheses
The Laryngoscope, 1998AbstractThe “ideal” prosthesis for ossicular reconstruction should, from a surgical standpoint, require easy manipulation, reduce surgeries to partial or total variants, and be constructed of stable, biocompatible material. From an acoustic standpoint, a prosthesis should weigh 10 to 40 mg, provide proper tension between the tympanic membrane (TM) and ...
