Morphology and Morphometry of the Asterion in the South African sample within KwaZulu-Natal
Introduction: The asterion is a meeting point formed by the union of the lambdoid, parieto-mastoid and occipito-mastoid sutures. It is the most common landmark in surgery due to its close relation to the transverse-sigmoid sinus junction. Population-specific differences were noted when determining t...

description | Introduction: The asterion is a meeting point formed by the union of the lambdoid, parieto-mastoid and occipito-mastoid sutures. It is the most common landmark in surgery due to its close relation to the transverse-sigmoid sinus junction. Population-specific differences were noted when determining the position of the asterion using external bony landmarks. Therefore, this study aimed to determine the anatomical position of the asterion in relation to external bony landmarks, and to determine the morphology of the asterion within the South African sample of KwaZulu-Natal. Materials and methods: Thirty-six dry adult skulls were obtained from the Department of Clinical Anatomy, University of KwaZulu-Natal. The morphology of the asterion was classified according to Morales Avalos et al. (2011). While, the morphometry regarding the position of the asterion were measured in accordance with Akkaşoğlu et al. (2019) methodology. Results: Type I asterion was observed in 18 (25.0%) of the cases and Type II presented in the majority of the cases with a prevalence of 75.0%. The distances from the asterion to the respective external bony landmarks were found to have no differences with regard to laterality (p > 0.05). The South African sample of KwaZulu-Natal was found to have majority of Type II present. The measurements from the asterion to the external bony landmarks were found to be very similar to an African based population. Conclusion: This study may enhance the existing body of knowledge regarding the morphology and morphometry of the asterion, which may lead to improved outcomes when analysing radiographs and for neuro-surgery. |
