Composite torps and porps for ossicular reconstruction

Use of 2‐Octyl cyanoacrylate in Cartilage Interposition Adherence During Ossiculoplasty

“…In the mid-1990s, Silverstein et al reported their use of a cyanoacrylate derivative for cartilage interposition adherence in 180 patients with Brackmann-modified TORPs and Sheehy-modified POP (Xomed, Jacksonville, FL), noting no dislocation or complications. 10 Similarly, in our patients, there were no adverse reactions as a result of the material. Additionally, our extrusion rate is consistent with published reports, indicating there is no increased erosion of the cartilage as a result of 2-octyl cyanoacrylate.…”

“…It has been noted safe to use in other aspects of otolaryngology as well: Brown et al studied the use of 2‐octyl cyanoacrylate with auricular cartilage in rabbits and found no difference in inflammatory reaction or migration when compared to nylon suture.

“…It has been studied in a variety of ophthalmologic, neurosurgical, and cardiothoracic procedures, among others. Early reports of use of cyanoacrylate derivatives in the middle ear to augment ossiculoplasty using hydroxyapatite prostheses exist; however, there are no detailed reports of extrusion rates using this technique in the long term with use of titanium prostheses. In this study, we review our method of utilizing Dermabond (Ethicon) for adhering a titanium ossicular prosthesis to the cartilage graft prior to insertion as a unit into the middle ear.…”

Acoustomechanical properties of open TTP® titanium middle ear prostheses

“…The surface of pure titanium is spontaneously covered with an oxide layer that consists mainly of titanium dioxide (TiO 2 ) which protects the metal from further corrosion. The high chemical stability of this oxide layer is responsible for the excellent compatibility of the prostheses with surrounding tissue (Schwager and Geyer, 1998;Silverstein et al, 1993).…”

“…In the past, middle ear prostheses for ossiculoplasty were developed and assessed primarily on the basis of criteria such as: (i) biostability, (ii) biocompatibility (Schwager, 1998;Schwager and Geyer, 1998;Treace, 1994) and (iii) clinical outcome (Applebaum, 1993;Bojrab et al, 1994;Fisch and Schmid, 1994;Geyer and Helms, 1993;Goldenberg, 1994;Goldenberg, 1992;Jahnke, 1987;Jahnke, 1992;Kessler et al, 1994Kinney, 1997Maassen and Zenner, 1998;Macias et al, 1995;McElveen et al, 1995;McElveen Jr., 1994;Rust et al, 1996;Schuring, 1994;Silverstein et al, 1993;Wehrs, Hearing Research 192 (2004) [36][37][38][39][40][41][42][43][44][45][46] www.elsevier.com/locate/heares 1994). This includes titanium prostheses like the TTP Ò (University of T€ ubingen Titanium Prostheses Ò , 27).…”
