| Description | The retraction pocket (RP) is an invagination of the tympanic membrane (TM) into the tympanic cavity. It is caused by recurrent or chronic negative pressure in the middle ear, which is secondary to dysfunction of the Eustachian tube (1,2). An alternative hypothesis for the pathogenesis is related to the persistence of an inflammatory reaction, secondary to otitis media (3). Retraction of the TM is one of the theories of genesis of the cholesteatoma (4,5). The aim of our study was to identify the morphological abnormalities of pars tensa RP and signs leading to the formation of cholesteatoma and to confirm that the RP is not only static invagination of the TM but it is an active process where inflammation plays a key role. |
