When the spine is misaligned it affects the normal draining of the Eustachian tubes. Stagnate water left in the ears provides a breeding ground for bacterial growth. A chiropractic adjustment releases the pressure on the tubes allowing normal drainage to occur and reduces the incidence of ear infections.
45 children with ear infections were treated with chiropractic care. 93% of the cases resolved under care. 75% within 10 days or less. J Manipulative Physiol Ther. 1996 Mar-Apr;19(3):169-77.
