The purpose of this study was to assess the structural characteristics of the styloid process (SP) using cone-beam computed tomography (CBCT) examination in patients with maxillofacial diseases. The study aimed to determine the prevalence of elongated styloid process (ESP) and its relationship to gender in the study population. Radiographic records of 498 subjects were evaluated retrospectively. Radiological examinations including measurements of the structure, length, volume, and angulations of styloid process were performed on CBCT images. Males had significantly longer styloid process in both sides than females in the study population and a strong positive linear relationship was found between left and right sides' process length (r = 0.83; p < 0.001). The mean internal oblique angle of styloid process differed between genders, but there were no statistically significant differences in the mean anterior oblique angle. Out of 498 subjects, 62 (24.13%) females and 101 (41.91%) males had elongated left styloid process (≥ 30 mm), while 75 (29.18%) and 90 (37.34%) had right side respectively.

This study presents the CBCT as an alternative method to CT or panoramic radiographs for the measurement and the assessment of the styloid process. Within the study in 498 subjects in China, it was observed that the males, on average, had significantly longer styloid process and narrower internal oblique angle than females either in left or right side. Around 33% of the study population had ESP.
本研究旨在通过锥形束计算机断层扫描（CBCT）检查评估颌面部疾病患者茎突（SP）的结构特征。该研究旨在确定茎突过长（ESP）在研究人群中的患病率及其与性别的关系。对498名受试者的影像学记录进行回顾性评估。在CBCT图像上进行包括茎突结构、长度、体积和角度测量在内的放射学检查。在研究人群中，男性双侧茎突明显比女性长，并且发现左右两侧茎突长度之间存在强正线性关系（r = 0.83；p < 0.001）。茎突的平均内斜角在性别之间存在差异，但平均前斜角没有统计学上的显著差异。在498名受试者中，62名（24.13%）女性和101名（41.91%）男性左侧茎突过长（≥30毫米），而右侧分别有75名（29.18%）和90名（37.34%）。

本研究表明，CBCT可作为一种替代CT或全景X线片的方法，用于茎突的测量和评估。在中国498名受试者的研究中，观察到男性平均而言，无论左侧还是右侧，茎突都明显比女性长，内斜角更窄。研究人群中约33%有茎突过长。
