IntroductionDisjunction of ossicular chain is a common finding in middle ear chronic disease. In addition to ossicular interposition, various materials have been used reconstruction, such as ceramic prostheses, polyethylene, and titanium.ObjectiveBecause of the high cost of the available options, the authors proposed to reconstruct the ossicular chain with resin cement, a material normally used in dental reconstruction and fixation.MethodsTwo anatomical parts of the temporal bones are be used, creating a disjunction of the ossicular chain between the anvil and stirrup and then rebuilding with resin cement. These reconstructions were repeated four times by three different surgeons to ensure the feasibility of the method.ResultsA total of 12 reconstructions were made, four per surgeon. After applying the cement, it could be verified by touch that the space was filled properly by the material used. Proper articulation with motion transfer to the entire ossicular chain was also observed.ConclusionResin cement is a suitable material in the reconstruction of ossicular chain injury, and it is inexpensive and technically simple.
