Aluminum Oxide Ceramic Ossicular Replacement Prosthesis

Annals of Otology, Rhinology and Laryngology, 1985
Two different prototypes of columella materials made from aluminum oxide ceramics were newly designed by the author for ossicular reconstruction. CORP-P (ceramic ossicular replacement prosthesis-partial) is used as a columella to fit onto the stapes head, and CORP-T (ceramic ossicular replacement prosthesis-total) is used as a columella placed onto the

Rapid prototyping of ossicular replacement prostheses

Applied Surface Science, 2007
Materials used in ossicular replacement prostheses must demonstrate appropriate biological compatibility, acoustic transmission, stability, and stiffness properties. Prostheses prepared using Teflon®, titanium, Ceravital and other conventional materials have demonstrated several problems, including migration, perforation of the tympanic membrane ...

Ossicular Replacement Prosthesis

Annals of Otology, Rhinology & Laryngology, 1973
A fixed footplate in a well aerated middle ear devoid of ossicles is generally acknowledged to be a difficult otologic reconstructive problem. A rapid method employing readily available materials is presented with several case reports. The method employs a combined alloplastic-tissue prosthesis which is easily assembled and inserted.

Total and partial ossicular replacement prostheses in children

Otolaryngology–Head and Neck Surgery, 1994
Although 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 ...

Failures with Plasti‐Pore Ossicular Replacement Prostheses

Otolaryngology–Head and Neck Surgery, 1984
Plasti‐Pore ossicular prosthesis failures found in our series of 246 patients with regular follow‐up are reported and analyzed. Extrusions as well as poor functional results (postoperative air‐bone gap greater than 25 dB) of the prostheses with and without cartilage on top have been reviewed. The overall extrusion rate was 9.3%: a higher extrusion rate

Magnetic ossicular replacement prosthesis

The Journal of the Acoustical Society of America, 1989
An ossicular replacement prosthesis containing a magnet in the head of the prosthesis so that when used with a magnetic induction hearing aid having a coil producing a magnetic field, the hearing losses resulting from insertion of the prosthesis and any other remaining hearing losses can be corrected without the difficulties associated with ...

Ossiculoplasty Failure with Ceramic Ossicular Replacement Prosthesis

ORL, 2010
The stability of ceramic ossicular replacement prosthesis (CORP) in the middle ear was evaluated in 162 ears that had been followed for more than 18 months. The CORP extruded from 8 ears (4.9%) and was dislocated in 6 ears (3.7%). These failures were considered to be due mainly to postoperative tubal dysfunction and disease recurrence.

High-resolution computerized tomography for ossicular replacement prostheses

Acta Otorrinolaringológica Española, 2023
To study the accuracy of high-resolution computed tomography (HRCT) for assessing the ossicular structures in cadaveric temporal bone by the distance between temporal bone elements is of great interest.To record the distances between the malleal neck and both the stapedial head and footplate by HRCT.

Experience With a Polyethylene Total Ossicular Replacement Prosthesis

Archives of Otolaryngology - Head and Neck Surgery, 1979
Surgical 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

2004
The 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 ...
