title: [Surgical treatment of acquired stenosis of the external auditory meatus (author's transl)].
abstract: Acquired stenosis caused by augmentation of the soft tissues usually are arrayed circulary and less diffusely; the posterior and superior wall seems to be favoured. Circular stenosis are to excise and to cover by a free skin flap. So the circular scars are changed into longitudinale and prevent a circular recurrent. Also after removal of a diffuse stenosis finally longitudinal stripes of skin are implanted with analogous effect. The transplantation of a new and healthy skin may work additionally against a shrinking-tendency of the local skin. The removal of bone is only needed exceptionally. We did not see any indication for a mastoidectomy and removal of the posterior bony wall; our last case should even demonstrate a contraindication.
