Biocompatible materials Proplast and Plastipore offer effective ossicular reconstruction for chronic otitis media hearing loss. Cartilage film can prevent extrusion issues in middle ear surgery.

Area of Science:

Otolaryngology
Biomaterials Science
Surgical Innovation

Background:

Chronic otitis media frequently causes hearing loss due to ossicular chain damage.
Traditional ossicular reconstruction methods have limitations.
Improving outcomes in middle ear surgery is crucial.

Purpose of the Study:

To evaluate the efficacy of Proplast and Plastipore for ossicular reconstruction.
To compare these materials with homologous grafts.
To identify strategies for mitigating complications in middle ear prostheses.

Main Methods:

A retrospective review of patients undergoing ossicular reconstruction using Proplast and Plastipore.
Three years of data for Proplast and two years for Plastipore were analyzed.

Assessment of audiological outcomes and complication rates, including extrusion.

Main Results:

Proplast and Plastipore yielded results comparable to homologous materials for ears lacking an incus and stapes arch.
These synthetic materials demonstrated advantages in ease of handling, time efficiency, and availability.
Extrusion of the prosthesis was a noted risk, consistent with foreign material use in infected middle ears.

Conclusions:

Proplast and Plastipore are suitable biocompatible materials for ossicular reconstruction in specific cases of chronic otitis media.
The use of cartilage film effectively addresses the risk of prosthesis extrusion.
These materials offer a viable alternative to homologous grafts, enhancing surgical outcomes and efficiency.
