We present the case of 4 adult subjects exhibiting asymmetry of the lateral atlantodental interval (within the accepted standard ranges of normal asymmetry equal or under 2mm) on open mouth x-ray examination. The asymmetry was clearly ameliorated after the Atlasprofilax procedure. Improvements in atlas tilt and axis spinous process deviation also were demonstrated. We discuss the preliminary validity of the Atlasprofilax non-invasive approach for treating such conditions and whether the debate on commonly accepted asymmetry in the lateral atlantodental interval should remain open and be further investigated. Asymmetry in lateral atlantodental interval or odontoidlateral mass interspaces through x-ray examination often has been found in healthy and unhealthy subjects and may be associated with atlantoaxial rotatory subluxation. Its clinical relevance remains a controversial subject. Some authors affirm that this asymmetry is a normal variant.
