Assessment of Anatomical Variation of Styloid Process in Multidetector Computed Tomography

Objective: This study aimed to assess the anatomical variation of styloid process Nepalese individuals by using multi-detector computed tomography scans. It was carried out establish baseline for normal length and compare variability measurement between different age group gender. Materials methods: quantitative, cross-sectional performed in Department Radiology Imaging, Tribhuvan University Teaching Hospital. Imaging data were collected over period January April 2021 with total number 153 individuals. The gender noted. done Multiplanar Reconstruction (MPR) coronal sections Head Neck, PNS Cerebral Angiography. Various Styloid Process (SP) morphology parameters like RLSP, RGSP, LLSP, LGSP, Right Elongation Type, Calcification Left Type measured. Results: SP found be 3.06±0.72 cm (ranged 1.80-5.54 cm) right while that left 3.08±0.72 1.45-5.69 cm). gap calcification pattern 0.51±0.30 0.08-1.20 0.63±0.43 0.08- 1.97cm). Similarly, there a statistical significant difference RLSP-RGSP LLSP-LGSP. higher among male than female. But no female measurement. series elongation patterns SP, followed elongated, distant pseudoarticulated, segmented SP. calcified nodular, partial, outlined Conclusion: In this study, valuable information regarding respect found. 3D CT reconstruction is gold standard investigation helps studying relation surrounding structures.
