| Abstract: | AIM: The aim of this study is to evaluate the thickness of occipital bones in dry skulls. INTRODUCTION: The occipito-cervical junction is the most cephal portion of the axial skeleton, connecting the cranium and the spine. It is a functional unit including the occiput, atlas and axis. The osseous complex allows significant mobility while maintaining biomechanical stability. Due to the anatomic complexity of this area a thorough understanding of the bony elements and about the involved soft-tissue elements is essential. MATERIALS AND METHODS: This study was carried out using skull bones from the Anatomy department, Saveetha dental college. Sample size of the study was 30 dry skulls, which was used to analyse the thickness of occipital bone. The thickness of the occipital bone was measured with a digital vernier calliper with an accuracy of ±0,002 mm. RESULT: The maximum thickness of the occipital bone can be measured at the external occipital protuberance- mean value of 12.2mm. Male skulls had higher bone thickness around this point. Female had a mean value of 9.3mm thickness at the external occipital protuberance and male had a mean value of 14.6mm around the area. The thickness below the superior nuchal line ranged between 1.4 and 7.3 mm respectively. The thickness above the superior nuchal line ranged between 2.3 and 8.5 respectively. CONCLUSION: The maximum thickness was high among males than in females. The maximum thickness of screw fixation in case of surgeries was found to be an average of 8mm. |
