To evaluate the type and prevalence of incidental findings from cone beam computed tomography (CBCT) of the maxillofacial region. Findings are divided into those that require (i) intervention/referral, (ii) monitoring, and (iii) no further evaluation.
Three hundred consecutive CBCT scans conducted in the University of North Carolina School of Dentistry Oral and Maxillofacial Radiology Clinic from January 1 to August 31, 2008 were retrospectively reviewed. Findings were categorized into airway, soft tissue calcifications, bone, temporomandibular joint (TMJ), endodontic, dental developmental, and pathological findings.
A total of 272 scans revealed 881 incidental findings (3.2 findings/scan). The most prevalent was airway findings (35%) followed by soft tissue calcifications (20%), bone (17.5%), TMJ (15.4%), endodontic (11.3%), dental developmental (0.7%), and pathological (0.1%). 16.1% required intervention/referral, 15.6% required monitoring, and the remainder (68.3%) required neither.
This study underscores the need to thoroughly examine all CBCT volumes for clinically significant findings within and beyond the region of interest.
评估颌面锥形束 CT（CBCT）的偶然发现的类型和发生率。这些发现分为需要（i）干预/转介、（ii）监测和（iii）无需进一步评估的情况。
回顾性分析 2008 年 1 月 1 日至 8 月 31 日在北卡罗来纳大学牙科学院口腔颌面放射科进行的 300 例连续 CBCT 扫描。将发现分为气道、软组织钙化、骨、颞下颌关节（TMJ）、牙髓、牙齿发育和病理发现。
共 272 例扫描显示 881 例偶然发现（每例扫描 3.2 例）。最常见的是气道发现（35%），其次是软组织钙化（20%）、骨（17.5%）、TMJ（15.4%）、牙髓（11.3%）、牙齿发育（0.7%）和病理（0.1%）。16.1%需要干预/转介，15.6%需要监测，其余（68.3%）不需要。
本研究强调需要彻底检查 CBCT 容积内和超出感兴趣区域的所有临床相关发现。
