    Introduction: The skull bone has numerous impressions formed by many important structures related to it. The impressions which are formed serve as an important tool for many purposes. Among them, the normal impressions of dural venous sinuses and their variations are of relatively significant value as it is used for neurosurgeons, radiologists, for investigating, and diagnosing various pathologies of dural venous sinuses such as thrombosis, embolism, and fistula. In such case, clear information on the morphometrical study of dural venous sinuses is lacking in literature. Thus, the study focuses on the morphometric evaluation of an impression of dural venous sinuses on skull bones. Materials and Methods: In the present study, a total of 50 dry human skull bones of unknown sex and without any gross breakage were collected from the Department of Anatomy, Saveetha Dental College and Hospitals, Chennai. The bones were subjected to visual and morphological analysis and evaluated. The present study involved the examination of an impression of superior sagittal sinus, right and left transverse sinus, sigmoid sinus, and occipital sinus in the skull. The length and width of these sinuses were measured with Vernier caliper. Results: The mean length of the superior sagittal sinus is 25.74 ± 1.13. The mean length of right and left transverse sinus is 4.87 ± 0.32 and 5.11 ± 0.48, respectively. The mean length of right and left sigmoid sinus is 3.84 ± 0.65 and on left sigmoid sinus is 3.91 ± 0.43. The mean length of the occipital sinus is 4.23 ± 0.54. The mean width of the superior sagittal sinus is 1.15 ± 0.072. The mean width of the right transverse sinus is 0.80 ± 0.044 and of the left transverse sinus is 0.82 ± 0.035. The mean width of the right sigmoid sinus is 0.91 ± 0.049 and of the left sigmoid sinus is 0.94 ± 0.027. The mean width of occipital sinus is 0.53 ± 0.022. The mean width of the confluence of sinuses is 1.36 ± 0.051. All the observed values are tabulated and expressed as mean ± standard deviation. Conclusion: It is concluded that this study will be valuable definitely for vascular neurosurgeons during pre-operative planning and radiologist to avoid misdiagnosis and misinterpretation.
