Abstract (EN):
The stapes, the smallest bone in the human body, is
the third component in the tympano-ossicular chain
of the middle ear. Otosclerosis is a disease that can
cause stapes fixation, resulting in different kind of
hearing losses. It is a disorder that involves the
growth of abnormal bone around stapes footplate.
The tonal and vocal audiometry, tympanometry,
and acoustic reflexes, are the most used diagnostic
tests. The treatment can be done by amplification
with hearing aids or more effective, by surgery. To
correct small focus of otosclerosis, Hough, in 1960,
suggested the implementation of a technique
(Figure 1) in which part of the anterior crura is
breached and the posterior one is rotated, getting
only the connection between the stapes footplate
and the inner ear made through the posterior crura
[Glasscock et al., 1995].
