“…They undergo slow replacement of non-viable bone by new bone formation through a process of "creeping substitution" [38,66]. Autogenous cortical bone grafts and homograft ossicles behave similarly [26,38,66] and can be utilized if autogenous ossicles are not available. Grafts made of cartilage often develop chondromalacia with loss of stiffness and a tendency to become resorbed [27,38,66].…”

Four decades after the introduction of tympanoplasty, the goal of achieving stable and long-term hearing improvement after tympanoplasty surgery for chronic otitis media continues to be elusive. In this review, we focus on the current status of our understanding of the mechanics and pathology of the middle ear after tympanoplasty surgery. We also analyze some problems and challenges faced by clinicians and basic scientists in the quest for improved postoperative hearing results.

“…The use of autograft ossicles in middle ear reconstruction was first reported by Hall and Rytzner (1957). Several studies on the use of autologous ossicles in tympanoplasty followed (Hall and Rytzner, 1960;Kerr and Smyth, 1971;Lang et al, 1986;Lang et al, 1989;Wake et al, 1992). One of the problems with the use of autograft ossicles in cholesteatomatous ear disease is that ossicular erosion due to the disease process itself limits its availability for reconstruction.…”

Autograft ossicle selection in cholesteatomatous ear disease: histopathological considerations

1997

In order to determine whether selection of autograft ossicles in cholesteatomatous ear disease should be based on upon their apperance under the surgical operating microscope, we studied the histopathological features of 113 such ossicles. We attempted to correlate the extent of erosion of the ossicle, as noted under the surgical operating microscope, with their histopathological apperance. There were 60 mallei and 53 incudes. Seventy-nine ossicles were eroded and 34 were intact. The commonest abnormality noted was erosion of the long process of the incus (75 per cent). Both intact and eroded ossicles had similar histological features. There was no evidence of intra-ossicular cholesteatoma. The results suggest that the extent of erosion of these ossicles as seen under the surgical operating microscope should in no wasy prejudice their use as autografts when required.

“…Titanium implants are also MRI compatible. The cost of implant, however, becomes an important issue in the developing nations, especially when the cost of the second [1][2][3][12][13][14][15][16][17][18][19] The current study reports mean postoperative ABG of 13.8 ± 4 dB and closure of ABG to 20 dB or less in 95% of the patients.…”

“…Like autologous ossicles, they undergo slow replacement of nonviable bone by new bone formation. [11][12][13][14] The last decade has brought titanium to the forefront. Numerous articles cite its advantages: Tissue compatibility, durability, rigidness, lightweight features and excellent acoustic capability.…”
