Ossiculoplasty with composite prostheses. PORP and TORP.
This article discusses the design of a composite prosthesis developed from a desire to combine the advantages of two synthetic materials. Hydroxyapatite can be used directly against the tympanic membrane, and Plastipore can be easily trimmed intraoperatively. The need for any human tissue can be eliminated; hearing results and extrusion rates appear comparable to other implants commonly used.
