After adenoidectomy I have continuous runny nose. While sleeping I can't breathe with the nose.

My son had an adenoidectomy surgery at age 7 but doctor didn’t remove the whole due to narrow nasal bone, as per doctor. My son came to recovery room after two and a half hours. However, we did the x-ray after the surgery and found that the adenoid is still enlarged and is still blocking the post nasal space. Second doctor advised us that there should be total removal, still adenoid is standing around 50 percent.
