Reconstruction of congenital stenosis of external auditory canal with a postauricular chondrocutaneous flap.
We describe here a new surgical technique for treatment of congenital stenosis of the external auditory canal using a postauricular chondrocutaneous flap. Our technique prevents recurring stenosis by cartilage support and provides a sufficient extension of the canal. The chondrocutaneous flap is safely elevated, easily reaches the canal, and has ample blood supply. It is beneficial for its self-cleaning function that the remnant canal, which contains cerumen glands, is used as part of the reconstructed canal. Six patients with congenital stenosis of the external auditory canal were treated by our procedure. In these patients, three patients were treated by a postauricular approach and the others were treated by an endaural approach. All patients had very satisfactory results.
