Lyophilized Partial Ossicular Replacement Allografts

Annals of Otology, Rhinology & Laryngology, 1982
This report deals with the use of partial ossicular replacement allografts (PORAs) in the stable ear, ie, a middle ear free of any residual or recurrent disease process such as fluid, cholesteatoma or infection. PORAs have been used by Shinn and Smith at the Ear Medical Clinic of Santa Clara Valley between July 1978 and December 1981; they are used to ...

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 ...

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.

On the use of 3D modeling, reconstruction and printing techniques for the development of a total ossicular replacement prosthesis: a case study of cholesteatoma

Biomedical Materials
The middle ear, which lies between the external auditory canal and the inner ear (cochlea), comprises the tympanic membrane, the ossicular chain (i.e. malleus, incus, and stapes), as well as the associated muscles, ligaments, and the middle ear cavity ...

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

Hearing results with the titanium ossicular replacement prostheses

European Archives of Oto-Rhino-Laryngology, 2005
The 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.

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.
