A case of congenital bilateral bony choanal atresia treated by surgery is reported. A new method of insertion and retention of the modelling tubes to prevent stenosis is described. This method has the following advantages: 1. it provides a good insertion and retention of the modelling tubes; 2. it doesn't provoke any trauma of the nasal septum, soft palate and nostril; 3. the insertion of the tubes doesn't require general anesthesia; 4. it's well tolerated.
