Hi. My son who is one year old, weight is 11 kg, is suffering from DNS, his right side of nose is completely blocked and water comes from his mouth, eyes and nose. While sleeping he experiences difficulty in breathing and voice comes from his chest. what is the treatment, can we get DNS operation for him, as he is just one year old? Are there any other method to open the nose say fitting a pipe in the nose etc? should I consult ENT specialist or paediatric specialist?
