T1 - Ossicular chain reconstruction

N2 - The prostheses available for reconstruction of the ossicular chain have expanded to include a variety of synthetic materials. Hydroxyapatite contains the inorganic constituents found in human living bone and is currently being incorporated into many new prostheses. This study demonstrates the computed tomography and magnetic resonance image characteristics of eight middle ear prostheses, a block of dense hydroxyapatite, and a human incus. Imaging of ossicular prostheses is more informative with computed tomography.

a synthetic prosthesis is used to reestablish the ossicular chain

This focus has led to a deficiency in knowledge about other areas of possible improvement, such as research into how to more accurately mimic the acoustic response of the ossicular chain with the shape of the prosthesis.

A total of 12 reconstructions were carried out, four per surgeon. After applying the cement, it could be verified by touch that the space was filled properly by the used material. Proper articulation with motion transfer to the entire ossicular chain was also observed.

Two anatomical parts of the temporal bones were used, creating a disjunction of the ossicular chain between the incus and staples and then reconstructing with resin cement. These reconstructions were repeated four times by three different surgeons to ensure the feasibility of the method.

In March 2006, two years after surgery, the patientunderwent appositional transtympanic drainage in the right ear dueto right chronic otitis media with effusion at the Complex Unit ofOtolaryngology and Neck Surgery of Monaldi Hospital (Naples,Italy); however, no substantial clinical improvement occurred. Thepatient experienced progressive worsening of right-ear hearingloss, otorrhea and otalgia, despite frequent antibiotic therapies(with quinolones and cephalosporins). Therefore, the patientunderwent petrous bone computed tomography (CT). The CT scanidentified an intratympanic mass that enveloped the ossicular chainwithout erosion and thickening of the tegmen tympani ().
