Figure 3 shows the audiograms for the ears with fibrotic aural atresia. All the audiograms show a large airbone gap due to the aural atresia.
The findings of this study identify a factor that has not been considered in previous investigations, that of a fibrotic tissue pathway in ears with fibrotic aural atresia.
In the ear with fibrotic aural atresia, the connection of the fibrotic tissue to the ossicles contributes to more efficient sound transmission by means of CC.
Whereas it is recognized that the incidence of aural atresia is relatively low, with an estimated annual incidence of 0.6 cases per 100,000 inhabitants [26], the estimated number of new cases per year in the United States is 2,000, which is not an insignificant number.

Some authors are not satisfied with classic surgical methods for treating aural atresias, and they favor instead the use of a KTP/532 laser (11) or more extensive surgery.
