The purpose of the present study was to determine the frequency of relevant nondental related incidental findings in cone-beam computed tomography (CBCT) of the head and neck.
Nine hundred ninety-nine images were retrospectively reviewed for incidental findings. Those were defined as carotid artery calcification (CAC), paranasal sinus findings (PSF), sialolithiasis of the parotid gland (SP) or submandibular gland (SSub), calcification of the ligamentum stylohyoideum (CLS), and Stafne bone cavity (SBC). All datasets obtained between 2010 and 2014 at a university-based school of dental medicine in Switzerland were reviewed. Demographic data such as age and sex were also recorded.
A total of 350 incidental findings within the 999 CBCT scans were identified. The most frequent finding was PSF (27.8%), followed by CLS (11.6%), CAC (5.3%), and SSub (0.8%). No SP or SBC was found. Incidental findings were most frequent between 61 and 70 years of age. Males had a higher prevalence in CAC, PSF, and SSub than females.
These results underscore the need for a complete examination of every CBCT image beyond the region of interest.
本研究旨在确定头颈部锥形束计算机断层扫描（CBCT）中与牙科无关的相关偶然发现的频率。
对999张图像进行回顾性分析以寻找偶然发现。这些发现被定义为颈动脉钙化（CAC）、鼻窦发现（PSF）、腮腺（SP）或下颌下腺（SSub）涎石病、茎突舌骨韧带钙化（CLS）和斯丹氏骨囊肿（SBC）。对2010年至2014年间在瑞士一所大学牙科学院获得的所有数据集进行了回顾。还记录了年龄和性别等人口统计学数据。
在999次CBCT扫描中总共发现了350个偶然发现。最常见的发现是PSF（27.8%），其次是CLS（11.6%）、CAC（5.3%）和SSub（0.8%）。未发现SP或SBC。偶然发现在61至70岁之间最为常见。男性在CAC、PSF和SSub方面的患病率高于女性。
这些结果强调了对感兴趣区域以外的每一张CBCT图像进行全面检查的必要性。
