The Study On Frequencies Of Anatomical Variations Of The Structures In The Retrotympanum

Abstract

The retrotympanum is a complex structure consisting of different spaces lying in the posterior wall of 
the tympanic cavity. The use of the endoscope for the removal of cholesteatoma matrix from the 
retrotympanum led to a decrease in cholesteatoma recidivism. Endoscopes were also used during 
second-look operations to detect residual cholesteatoma.
