[Reconstruction of the middle ear with passive implants]

Area of Science:

• Otolaryngology
• Biomaterials Science
• Surgical Reconstruction

Background:

• Middle ear reconstruction techniques include no reconstruction, autologous ossicles, passive alloplastic implants, and active implants.
• Reconstruction using passive middle ear implants has gained prominence due to limitations of autologous grafts.
• Autologous ossicles face a significant resorption rate (approx. 15%) in inflamed mucosal environments.

Purpose of the Study:

• To provide an overview of optimal reconstruction solutions for common ossicular chain defects.
• To compare the efficacy and benefits of alloplastic prostheses against autologous ossicles.
• To highlight advancements in passive middle ear implant technology.

Main Methods:

• Review of current literature on middle ear reconstruction techniques.
• Analysis of material properties and biocompatibility of modern alloplastic implants.
• Evaluation of coupling and functional elements in passive prostheses design.

Main Results:

• Modern alloplastic implants exhibit high biocompatibility and resistance to inflammatory processes.
• These implants are lightweight, rigid, and offer enhanced coupling to the residual ossicular chain.
• Integrated coupling and functional elements improve prosthetic performance.

Conclusions:

• Passive alloplastic implants represent a highly effective alternative for middle ear reconstruction.
• Alloplastic prostheses overcome the resorption issues associated with autologous ossicles.
• Advancements in implant design offer superior functional outcomes in ossicular chain reconstruction.
