Tomorrow's Prosthetic Implants May Be Made of This New Titanium Alloy

The HAP material has been coated (Figure-1, Osseous Tita-HAP ossicular prosthesis, EON Meditech Pvt. Ltd.) with strength >15MPa on Titanium disk having Ca/P ratio 1.67/1.76. This development provides excellent Tympanic Membrane fixation with prosthesis.

current Trends in Middle Ear Surgery Ossiculoplasty And Stapedioplasty With Titanium Prostheses

Both Hydroxyapatite (HAP) and Titanium (Ti) are well-accepted alloplastic materials for ossicular prostheses. Many different designs of HAP and Ti prostheses are presently available1. Prostheses using both types of biomaterial gave good functional results and stability with low extrusion rates, with no statistically significant differences between the two. Nevertheless, extrusions could be seen during long -term follow-up in both materials2.

HAP coated Titanium ossicular prosthesis (Osseous Tita-HAP, EON Meditech Pvt. Ltd.) can be used directly against the tympanic membrane without the need for cartilage interposition. Cartilage, of course, may be used if this is the surgeon’s preference.

Both materials are having their own advantage with ossicular prosthesis. The addition of different amount of inclusions in presently available titanium ossicular prosthesis gives combine advantage of both materials. The development focuses on combining HAP and Ti for better results.

Titanium implants provide comparable hearing improvement compared with other materials. The extrusion rate seems quite low if cartilage interposition graft is inserted. Its ease of handling, biocompatible properties, and sound conducting properties improve its efficacy as an ossicular prosthesis. Overall extrusion rate with Titanium Ossicular implants was

AB - Objective: To compare the effectiveness of two stapes prostheses in hearing improvement of patients undergoing stapes surgery for otosclerosis. Study Design: Retrospective chart review. Methods: Titanium and Teflon wire stapes prostheses were compared with regard to effectiveness in closing the air-bone gap. The charts of 461 stapedectomies performed by one sturgeon from 1996 to 2001 were reviewed. Patients who underwent stapedectomy for reasons other than otosclerosis, revision cases, and those with inadequate preoperative or postoperative bone-conduction threshold data were excluded. Small fenestra technique using either laser or drill was used for all patients. Inclusion criteria were met by 218 patients. Patients were then grouped according to type of prosthesis used, and hearing outcomes were compared. Measured outcomes were four frequency air-bone gap closure, pure-tone threshold, and rate of sensorineural hearing loss (SNHL). Results: The study group was comprised of 35 titanium and 183 Teflon wire prostheses. Closure of the air-bone gap to less than 10 dB was achieved in 86% of the patients with Teflon prosthesis compared with 71% of those with titanium prostheses. The groups were equivalent in regard to site of otosclerotic disease as well as technique, laser or drill, used to create the fenestra. Rate of SNHL was low for both groups and not significantly different. Conclusions: Both prostheses provided comparable results, although the Teflon platinum wire prosthesis was slightly superior. The smaller numbers in the titanium group may confound these results. The design of the titanium prosthesis provides a crimp that is circumferential around the incus, and that prosthesis was selected in cases with a narrow incus. The selection bias may also influence the results seen in this study.

The titanium-coated coxa prosthesis of the utility model is characterized in that by arranging a layer of titanium coat on the outer surface of the handle body of the coxa prosthesis, the roughness and the porosity degree of the surface of the prosthesis are increased, a rough surface as well as a joint surface with fine pores are formed on the surface of the prosthesis, not only the joint area of the bone and the prosthesis is increased, but also the newborn bone is ensured to grow in the pores of the coat, the joint strength of the interface of the newborn bone and the prosthesis is increased, and the fixing effect and the service life of the prosthesis are improved.
