The purpose of this study was to assess the structural characteristics of styloid process (SP) by cone-beam computed tomography (CBCT) examination in a patient population suffering from orofacial pain. The second aim was to assess the prevalence of elongated SP and its relation to gender, site and subjective symptoms in the study population.
Clinical and radiographic records of 208 patients were evaluated retrospectively. Radiological examinations including measurements of the structure, length, and medial angulations of SP were performed on CBCT images.
Out of 208 patients, 96 (46%) had not-elongated SP, 28 (13%) had left side, 16 (8%) had right side, and 68 (33%) had bilateral elongation of SP. The patients with elongated SP had significantly decreased angle values. There were no statistically significant differences in length values of SP between males and females in both groups. Significantly increased prevalence of symptoms except headache was observed in patients with elongated SP.
This study presents the CBCT as an alternative method to CT or panoramic radiographs for the measurement and the assessment of the styloid process. Patients suffering from orofacial pain, who also had elongated SP, had increased rate of corresponding neurological complaints compared with non-elongated ones.
本研究旨在通过锥形束 CT（CBCT）检查评估患有口腔颌面疼痛患者的茎突结构特征。第二个目的是评估研究人群中伸长的茎突的发生率及其与性别、部位和主观症状的关系。
回顾性评估了 208 名患者的临床和放射学记录。在 CBCT 图像上进行了包括结构、长度和茎突内侧角度测量的影像学检查。
在 208 名患者中，96 名（46%）无伸长的茎突，28 名（13%）左侧，16 名（8%）右侧，68 名（33%）双侧伸长的茎突。伸长的茎突患者的角度值明显降低。在两组中，男性和女性的茎突长度值均无统计学差异。在伸长的茎突患者中，除头痛外，其他症状的发生率明显增加。
本研究提出 CBCT 可作为 CT 或全景片的替代方法，用于测量和评估茎突。与非伸长的茎突相比，患有口腔颌面疼痛且茎突伸长的患者，相应的神经症状发生率增加。
