Autograft ossicle selection in cholesteatomatous ear disease: histopathological considerations

Abstract

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.

Middle Ear Cleft in Chronic Otitis Media: A Clinicohistopathological Study

“…Though ossicular necrosis is more in tubotympanic otitis media, several studies [11,12] show variable percentage. Incidence of ossicular involvement of even up to [90% in atticoantral otitis media has been reported [13]. No ossicular involvement by squamous epithelium/cholesteatoma similar to our study was also reported by Rupa et al [13].…”

Kolesteatom Olgusunda İşitme Kaybının Eşlik Etmediği İzole İnkus Kısa Kolu Destrüksiyonu

“…In the previously reported case, there was no difference in the audiograms performed during the pre-and post-operative periods. The gap of 15 dB in both observations was attributed to the absence of the short process of the incus and incudal ligaments (8). However, in our case, we encountered the opposite finding.…”

Mechanical treatment and autoclaving of middle ear ossicles from cholesteatomatous ears

“…However, their use in patients with cholesteatoma has been limited by the risk of harbouring residual disease. The changes in the middle ear ossicles in cholestematous ears have been described in several histological studies [2][3][4][5][6][7][8][9][10]. However, the deeper invasion of cholesteatoma into the middle ear ossicles has never been published.…”

“…However, their use in cholesteatoma ears has been limited by the possibility of harbouring within them residual cholesteatoma. There appears to be some evidence that the microscopic residuum of squamous cell epithelium in the ossicles could lead to reimplantation of the cholesteatoma [2][3][4][5][6][7][8][9][10]. The risk of cholesteatoma transmission using the autologous ossicles is widely accepted.…”
