Abstract
Objective: The scarce literature data on the mean length of the styloid process in the Iraqi population gave rise to the need for this study to determine the mean length of the styloid process in an Iraqi subpopulation, highlighting the possible importance in clinical and surgical conditions considered.
Methods: Cone-Beam Computed Tomography (CBCT) images of 229 Iraqi patients comprising 73 males (31.1%) and 156 females (68.9%), with a mean age of 40.48 ±16.326, were included in this retrospective study. The data obtained were transformed into SPSS v25, and descriptive and inferential analyses were performed.
Results: The mean length of the styloid process in males was found to be 26.16 ±1.08324mm on the right side and 26.42±1.12595mm on the left side, while the mean length of styloid process in females was found to be 26.13±1.12595mm on the right side and 26.15±0.74133mm on the left side.
Conclusions: There was no statistically significant difference in the length of the styloid process between the two sex groups (p > 0.05) or between the right and left sides of each sex group (p > 0.05).
