Introduction: The atlanto-occipital joint strains predominantly induce a tension-like headache which is caused as a result of a prolonged and an inappropriate posture which results from a poor ergonomic adaptation. Superior articulating facets on atlas are usually concave, with concavity in both longitudinal and transverse directions. However, variations have been reported in shape of its superior articulating surfaces. The anatomy of the atlas is essential to understand the basis for Craniovertebral junction anomalies and their surgical correction. Material and Methods: This study was conducted at the Department of Anatomy of Shija Academy of Health Sciences, Imphal, Manipur. During routine undergraduate studies, variant superior articulating surfaces of atlas were observed in 10 bones.  Result: Out of the 10 cases, three cases were observed to have comma shaped articulating surfaces,dumb bell shaped was observed in one vertebrae and complete separation of articulating surfaces was seen in fourvertebrae along with two vertebrae showing irregular superior articulating facets. Conclusion: In recent years, considerable innovations in the internal fixation techniques have created a need for more detailed quantitative description of the anatomy of this bone. Thus, the anatomy of the cervical vertebrae or the spine is of great clinical importance to surgeons, as a surgical procedure may be done through the anterior or posterior cervical spine, with gratifying results
