[Choanal atresia repair in Germany : Resection of dorsal septal parts and stents in focus].

backgroundVarious surgical techniques using transpalatinal, transseptal, and transnasal approaches for surgical repair of choanal atresia have been developed over the past 200 years. Endoscopic endonasal surgery with resection of dorsal septal parts and without the use of stents is the current scientific trend, as high success rates with low complication rates can be achieved. This study examined whether this technique has actually become standard in Germany, and also investigates the role played by stents.

methodsA total of 52 ear, nose, and throat (ENT) hospitals in Germany, including all 39 university ENT hospitals and 13 non-university maximum-care ENT hospitals, were asked which surgical technique they use for choanal atresia repair and whether stents are used.

resultsFor dorsal septal resection, 39 of 44 responding hospitals (89%) indicated that they resect dorsal septal parts, 85% of the university hospitals and 100% of the non-university hospitals. For use of stents, 20 of 48 responding hospitals (42%) reported not using stents, whereas 39% of the university hospitals and 50% of the non-university hospitals do use them.

conclusionEndoscopic endonasal choanal atresia repair with resection of dorsal septal parts is, in most instances, used as the standard technique in large ENT hospitals in Germany. Routine use of stents is still widespread. The future aim should be to reduce the use of stents in the treatment of choanal atresia and to use this method only in difficult, individual cases.
