ABSTRACT
The main problem of acquired external auditory canal atresia is the low efficacy of surgical treatment due to high risk of restenosis. The authors have developed a method for elimination of atresia, aimed at the removal of causes of restenosis. It includes the expansion of the external auditory canal, the formation of a skin flap on the feeding base of the anterior wall of the external auditory canal, a prolonged tamponade and the use of a silicone protector. 20 patients have been operated using this method. Air conduction was improved by 23±5 dB and bone-air interval was decreased from 43±2 dB to 30±2 dB. Due to conservative treatment, the result was preserved in 80% of patients.
