Reconstruction of old radical cavities.

The methods as well as the primary and late results of 74 partial and 93 total reconstructions of old radical cavities were described. In partial reconstructions the tympanic cavity was reconstructed, but the cavity was not eliminated, as it was dry or could be kept dry. In total reconstructions the tympanic cavity and auditory canal were reconstructed, and in most cases the cavity was obliterated, either by muscle or by combined grafts of muscle, tragal cartilage, and homologous septal cartilage. On the basis of the late results, functionally 10--20% poorer than the primary ones, the indications for reconstruction of old radical cavities were discussed. If there is chronic aural discharge, and if the cavity is lined with granulations, the ear can be rendered dry by total reconstruction in 90% of the cases.
