The purpose of this case report is to discuss and illustrate the clinical usage of Cone Beam Computed Tomography (CBCT) for the diagnosis of maxillofacial fractures in a traumatized patient. In this presentation, a 30-year-old male patient who was referred to Oral Diagnosis and Radiology Department with a limitation of mouth opening was reported. The history of the patient revealed a traumatic injury on his face because of a fall. The patient was initially examined by a medical practitioner in the emergency department of a public hospital. According to 2D cephalometric analysis, no fracture existed. Panoramic radiograph and postero-anterior reverse-town showed bilateral condyle fractures. In addition, a fracture in the left mandibular incisor region could clearly be detected on the panoramic radiograph. For further diagnosis, digital images were taken with CBCT. Cross-sectional views showed two vertical fracture lines on the alveolar bone between teeth numbers 17, 18 and 14, 15. A palatal root fracture was observed associated with tooth number 18. A fracture line in the left mandibular incisor region as well as bilateral condyle fractures could be seen clearly on CBCT views. CBCT is becoming a popular tool in modern dental practise. In the diagnosis of dentoalveolar fractures, CBCT has made it possible for the practitioner to get more detailed information.
本病例报告旨在讨论并说明锥形束 CT(CBCT)在诊断创伤患者颌面骨折中的临床应用。在本次报告中,一名 30 岁男性患者因张口受限被转诊至口腔诊断和放射科。患者的病史显示,他因摔倒而面部受伤。患者最初在公立医院急诊室由一名医生进行了检查。根据二维头颅分析,未发现骨折。全景片和后前位反转片显示双侧髁突骨折。此外,全景片上可清晰显示左侧下颌切牙区域的骨折。为进一步诊断,使用 CBCT 拍摄数字图像。横截面图像显示在 17、18 号牙和 14、15 号牙之间的牙槽骨上有两条垂直的骨折线。18 号牙伴有腭根骨折。CBCT 图像上可清晰显示左侧下颌切牙区域以及双侧髁突骨折。CBCT 在现代牙科实践中越来越受欢迎。在诊断牙槽骨骨折方面,CBCT 使医生能够获得更详细的信息。
