Mar 19, 2021 · Ossicular Interposition.—Ossicular interposition refers to reconstruction of a discontinuous or eroded ossicular chain with use of an ossicular graft (commonly the incus). This type of graft can be autologous (from the patient) or homologous (from a cadaver or donor) .
Use of incus as an interposition graft in ossiculoplasty for type …
May 1, 2015 · Conclusions: Autologous incus is an excellent interposition graft for ossiculoplasty. There is no risk of transmission of disease and no extra cost involved. Higher values of Middle Ear Risk Index, oedematous middle ear mucosa and Eustachian tube dysfunction are poor prognostic factor for success of ossiculoplasty.

Jul 1, 2023 · Incus interposition graft. Axial (A) and coronal (B) images of the right temporal bone demonstrate tympanoplasty with incus interposition graft articulating via a notch with the head of the stapes medially (arrow) and with the tympanic membrane graft laterally.
Comparison of Hydroxyapatite Prosthesis and Incus Interposition …
Jun 1, 2017 · In this study, the hydroxyapatite prosthesis, used for repair of the incus defect, was compared with the incus interposition. Between 2010 and 2016, 27 female and 16 male patients who underwent ossiculoplasty due to an incus defect were studied retrospectively. Patients’ hearing results at the sixth month were compared.

Jun 24, 2017 · Ossicular interposition grafting is a form of ossicular reconstruction (Type 3 tympanoplasty mechanism) that consists of resecting the malleus head or incus and then reinserting it between the stapes and either the malleus manubrium or tympanic membrane after it has been sculpted with a drill bur.
direct columellar action from the graft through the prosthesis and then through the stapes superstructure or footplate to the fluids of the inner ear. This action takes advantage of the hydraulic principle of converting low-
