Morphometric Analysis of the Clivus in Human Dry Skulls: A Radioanatomical Study
Journal Title: Ankara Üniversitesi Tıp Fakültesi Mecmuası - Year 2019, Vol 72, Issue 2
Abstract
Objectives: This study aims to reveal morphometric properties of the clivus including length, width and angle to the base of the skull from the perspective of skull base procedures. Materials and Methods: Twenty-four human dry skulls were included in the inventory of Mersin University Medical Faculty Anatomy Department. Direct anatomic measurements (DAM) were performed using digital caliper and digital image analysis software. Radiological analysis was performed using computed tomography (CT). Results: The length and inner surface area of the clivus for DAM and CT were 25.17±3.98/24.83±3.91 mm and 546.51±66.44/523.37±87.48 mm2, respectively. Clival angle (Welcher angle) for DAM and CT was 126.12±9.51°/124.37±10.86°. No statistically significant difference was found between the numerical data obtained by DAM and CT (p>0.05). Conclusion: Considering that clivus anomalies are associated with diseases such as platybasia, basilar invagination, CHARGE syndrome or Chiari type I, the data of the present study can be used for the detection of clivus anomalies as well as choosing the type of approach to the skull base.
