Abstract

Objective: The aim of this study is to compare the diagnostic value of two-dimensional (2D) CT and three-dimensional (3D) CT reconstruction techniques in detecting maxillofacial fractures in patients at Mzuzu Central Hospital (MCH).

Methods: 67 maxillofacial trauma patients admitted to Mzuzu Central Hospital from Jan to Sep 2024 underwent multi-slice spiral CT (MSCT) scanning. Images were post-processed using 2D and 3D reconstruction techniques. Clinical and radiological data were collected from the patients, and a comparative analysis of the results from the two reconstruction techniques was performed.

Results: In this study, 52 cases of maxillofacial fractures with a total of 83 fractures were diagnosed by 2D CT reconstruction technology, with a fracture detection rate of 77.61% (52/67). Using 3D CT reconstruction technology, 54 cases of maxillofacial fractures with a total of 91 fractures were diagnosed, and the fracture detection rate was 80.60% (54/67). Statistical analysis showed no significant difference in the detection rate of maxillofacial fractures between 2D CT and 3D CT reconstruction (χ² = 35.945, P = 0.687). In the diagnosis of zygomatic fractures, nasal fractures, and upper and lower jaw fractures, 3D CT reconstruction images have obvious advantages over 2D CT in displaying fracture displacement and fracture line course. However, for the display of comminuted fractures combined with sphenoid and ethmoid fractures, the cross-sectional images of 2D CT show higher superiority.

Conclusion: 2D CT reconstruction is a basic diagnostic tool for maxillofacial fractures. 3D reconstruction, with high detection and multi-angle visualization, offers valuable imaging for clinical decision-making, aiding in surgery planning. A combined approach, leveraging the strengths of both modalities, is pivotal for comprehensive assessment and management of maxillofacial trauma.

二维和三维CT重建检测马拉维Mzuzu中心医院颌面骨折的实验对比研究。

目的：比较二维（2D） CT和三维（3D） CT重建技术对妈祖祖中心医院（MCH）患者颌面部骨折的诊断价值。方法：对2024年1 - 9月在妈祖市中心医院收治的67例颌面部外伤患者行多层螺旋CT （MSCT）扫描。使用二维和三维重建技术对图像进行后期处理。收集了患者的临床和影像学资料，并对两种重建技术的结果进行了比较分析。结果：本研究通过二维CT重建技术诊断颌面部骨折52例，共83例骨折，骨折检出率77.61%（52/67）。应用三维CT重建技术，诊断颌面部骨折54例，共91处骨折，骨折检出率为80.60%（54/67）。统计分析显示，二维CT与三维CT重建对颌面部骨折的检出率差异无统计学意义（χ2 = 35.945, P = 0.687）。在颧骨骨折、鼻骨折、上下颌骨折的诊断中，3D CT重建图像在显示骨折位移和骨折线走向方面比2D CT有明显优势。但对于粉碎性骨折合并蝶筛骨折的显示，2D CT横断面图像显示出更高的优越性。结论：二维CT重建是颌面部骨折的基本诊断工具。三维重建具有高检出率和多角度可视化，为临床决策提供了有价值的成像，有助于手术计划。综合利用两种方法的优势，对颌面部创伤的综合评估和管理至关重要。

期刊介绍： Driven and guided by the priorities articulated in the Malawi National Health Research Agenda, the Malawi Medical Journal publishes original research, short reports, case reports, viewpoints, insightful editorials and commentaries that are of high quality, informative and applicable to the Malawian and sub-Saharan Africa regions. Our particular interest is to publish evidence-based research that impacts and informs national health policies and medical practice in Malawi and the broader region. Topics covered in the journal include, but are not limited to: - Communicable diseases (HIV and AIDS, Malaria, TB, etc.) - Non-communicable diseases (Cardiovascular diseases, cancer, diabetes, etc.) - Sexual and Reproductive Health (Adolescent health, education, pregnancy and abortion, STDs and HIV and AIDS, etc.) - Mental health - Environmental health - Nutrition - Health systems and health policy (Leadership, ethics, and governance) - Community systems strengthening research - Injury, trauma, and surgical disorders
