[Pockets of tympanic membrane retraction].
The pathogenesis of tympanic retraction pockets is analyzed. Middle-ear pressure and the behavior of the lamina propria and stratified squamous epithelium of the tympanic membrane were considered. Predisposing factors are discussed. Conservative surgical treatment is recommended for retraction pockets that are not adhered to the walls of the middle ear. Radical surgery should be reserved for adhered pockets. The management of mastoid cavities is discussed.
