title: [Advantages and disadvantages of the application of endoscopic techniques at different stages of tympanoplasty].
abstract: The objective of this work was to evaluate advantages and disadvantages of selected tympanoplastic stages under the endoscopic control during the surgical treatment of 93 patients presenting with chronic otitis media. The endoscopic techniques has indisputable advantages over traditional surgical microscopy when applied to elucidate the character and extent of the pathological process in the middle ear. This method allows to reveal granulation and cholesteatoma in difficult of access pockets and folds of the middle ear without enlargement of the extent of surgical intervention, to evaluate the "continuity" of the chain of auditory ossicles, etc. At the same time the use of an endoscope during performance of the majority of tympanoplastic procedures creates some difficulties related to the necessity of regular cleaning of the instrument and the impossibility of application of the bimanual technique.
