37 children with chronic tonsillitis were treated by manipulation. Tonsillitis disappeared in 25 of them. "Tonsillitis goes hand in hand with movement restriction in the craniocervical junction."
Of 76 children with chronic tonsillitis and movement restriction at the craniocervical junction, 70 had spinal dysfunction between the occiput and atlas. 37 children who had not been operated on were given manipulation and were followed up for 5 years. 67.6% were cured of tonsillitis entirely, the remainder relapsed and were treated again with manipulation. 25 had their tonsils surgically removed, but 19 of these still suffered from movement restriction after surgery, requiring manipulation for relief.
