[Aspects of surgical management of choanal atresia (author's transl)].

The indication for surgery of choanal atresia appears not uniform. In newborns the bilateral choanal atresia should be operated in the first days or weeks on account of threatening life complications. Unilateral atresia can be managed between the 3rd to 5th year; until this time the topographic conditions are enlarged nearly twice, which means much better conditions for operation. In the checked up cases (27 patients) the rate of relapse of the different surgical methods are explained. On account of a better view over the operating area and optimal plastic-surgical supply the transpalatinal approach is preferred especially in newborns and infants under microsurgical conditions and a description of the technique is given.
