INTRODUCTION: @entity1181 and exostoses of the external auditory canal are @entity5 arising in bones, leading to its obstruction and causing @entity393 . The treatment of these entities may present a therapeutic dilemma. AIM OF THE STUDY: To assess epidemiological and clinical data and surgical treatment effectiveness. SUBJECTS AND METHODS: The study group consisted of 21 @entity1 (14 @entity1 and 7 @entity1 ) between 18 to 63 years of age, treated in the Otorhinolaryngology Department of Medical University of @entity235  sk from 1995 to 2009. The results of audiometric, radiological and histopathological examination were taken into consideration. RESULTS: @entity1181 developing in tympanosquamous suture in 5 @entity1 , in tympanomastoid suture in 4. Bilateral exostoses occured in 12 @entity1 in anterior, posterior and inferior wall of the external auditory canal. In all @entity1 : conductive @entity393 ranged from 15 to 30 dB (average 29.9 dB), in 6 @entity1 with concomitant sensorineural component. @entity1181 were removed via intrauricular approach according to Mawson-Goodhill's method. Exostoses were removed via intrauricular, intracanal or postauricular approach. Histological examination confirmed benign overgrowth of compact and trabecular bone. The auditory canal was successfully reamed, the hearing improved in all @entity1 . CONCLUSIONS: @entity1181 are @entity5 leading to obstruction of the external auditory canal. @entity11343 is the overgrowth of the external auditory canal's compact bone in adults. @entity1181 and exostoses may lead to @entity393 . Indications to surgical treatment are @entity158 , progressive @entity393 and recurrent @entity2346 external.
