    Introduction: A small elevation on the orbital surface of the zygomatic bone just behind and within the orbital margin, about 11 mm below the frontozygomatic suture, is the Whitnall’s tubercle. It serves as an attachment for the check ligament of the lateral rectus muscle, the lateral palpebral ligament, the suspensory ligament of Lockwood, and the levator palpebrae superioris muscle. Materials and Methods: Dry human skull bones were obtained from the Department of Anatomy, Saveetha Dental and Hospitals, Chennai. A total of 50 skull bones were analyzed for the presence and prominence of Whitnall’s tubercle. The length, distance from the location of tubercle to the frontozygomatic suture and the height of orbital suture were evaluated morphometrically, using a sliding Vernier caliper. Results: An overall mean for these three parameters was calculated using the data obtained. There were no significant differences between the left and right sides. Conclusion: Even though human skulls develop from bilateral symmetric osteogenesis, surgeons should always be aware of possible asymmetry and possible absence of Whitnall’s tubercle between sides or among individuals.
