Abstract：Objective To explore new strategies and methods to prevent re-atresia/restenosis of reconstructed exter?nal auditory meatus (Re-EAMs) for congenital aural atresia/stenosis patients. Methods according to the reatresia/resteno?sis characteristics of Re-EAMs observed by the authors, a series of new prevention strategies, methods and relevant patent products are designed, measures include in improving types and methods of the covering epithelium with all kinds of free skin&skin flap, simulating function of the tympanic rings and supporting&expanding Re-EAMs Results the restenosis/reatre?sia rate split for thickness skin graft by mosaic 16.9%(10/59) is significantly lower than those of Thiersch’s skin graft in bar?rel-like 34%(17/50) (p<0.05) and mosaic 45.5%(15/33) (p<0.01), and there was no difference between the later two and oth?er measures (p>0.05). The artificial tympanic ring make good effect, and the EAM expandor and EAM model bracket execute the function well. Conclusion It is a new effective method to prevent restenosis/reatresia of the Re-EAMs) by mosaic grafting free thickness skin , implanting artificial tympanic ring, and supporting&. expanding Re-EAMs by EAM expandor and EAM model bracket, and worth of application .
