The biologic reconstruction efforts included both auto- and homografts.Autografts included bone chips from the mastoid cortex and ossicles usually consisting of a portion of the incus or malleus.The alloplastic materials used have included Polycel, Plastipore, Bioglass, and Ceravital [9–14].

A Teflon polymer, Proplast, had all the disadvantages of Teflon, particularly substantial reactivity in the middle ear .
A high-density polyethylene sponge, a machine-tooled form known as Plastipore, was then explored as an alternative and found to be a material that could be sculpted and shaped [13, 14, 26].
These pores in the Proplast material also allowed host fluids to infiltrate the prosthesis and facilitate the acceptance of the prosthesis.
The unique problem with this prosthesis was its Teflon shaft, which was not amenable to contouring.
Use of homografts requires special banks that might not be widely available.
The 1970s brought additional interest into trying to overcome the deficiencies of the autograft, homograft, and plastic implants of the 1950s and 1960s.

Evaluate a porous polyethylene prosthesis with two-point stabilization in total ossiculoplasty. All patients who underwent total ossiculoplasty during the years 2004–2007 were included in the study group.This approach utilizes a lateral as well as a medial graft to stabilize a total ossicular prosthesis (TOP). Retrospective cohort review of total ossiculoplasty. Only five patients (10%) had primary surgery whereas 45 (90%) underwent revision surgery. Audiometric results following total ossiculoplasty surgery using two-point stabilization exceeded results from the otologic literature.Proplast, a combination of two polymers, had a number of advantages that could be utilized for middle ear reconstruction .A high percentage of Proplast’s volume is porous to allow for tissue integration and to prevent excessive host graft rejection.Numerous technical advances have improved hearing results and long-term results.With the major innovation of utilizing cartilage as an interface between the prosthesis and the tympanic membrane, extrusions have been reduced.The early results were promising, with understanding that the grafts would become part of the host environment.Fusion of the bone graft to the malleus and stapes or footplate should achieve perpendicular action with good sound transmission .Aside from the residual microscopic cholesteatoma disease, once modified, the malleus or incus might not be long enough, particularly in total ossiculoplasty .Homografts were one of the first reconstructive options but later fell out of favor due to the increased resorption and possible infectious transmission .
