喉部软骨闭合性骨折12例MSCT诊断分析

MSCT Diagnosis of 12 Cases of Closed Fractures of the Laryngeal Cartilage

目的:探讨多排螺旋CT在喉部软骨闭合性骨折诊断中的临床应用。方法:对12例喉部软骨闭合性骨折患者进行MSCT扫描,利用窄窗宽低窗位及多平面重组等技术进行诊断分析。结果:12例患者中,甲状软骨板骨折6例(左侧4例,右侧2例),甲状软骨左右板融合处骨折4例,环状软骨骨折2例,合并声带挫伤6例,伴有喉旁软组织积气2例,引起上气道变形变窄1例。结论:MSCT能够很好地显示喉部软骨闭合性骨折,并能了解上气道有无狭窄及周围软组织的情况,能为临床选择治疗方案提供帮助。

Objective To investigate the clinical application of multi - slice computed tomography （MSCT） in the diagnosis of closed fracture of laryngeal cartilage. Methods MSCT scan was performed in 12 patients with closed fracture of larynx, and the diag- nostic analysis was carried out by using the technology of narrow window width and low window position and multi plane reconstruction. Results in the 12 cases, 6 cases of the thyroid cartilage plate fracture （4 cases of left side, 2 cases of right side）, 4 case of the frac- ture of the left and right side plate of thyroid cartilage 2 cases of annular cartilage fracture, 6 cases of combined vocal cord injury, 2 ca- ses of soft tissue product gas, 1 cases of upper airway deformation. Conclusion MSCT can well display the closed fractures of the la- ryngeal cartilage, and can understand the situation of the upper airway and the surrounding soft tissues, and can provide help for the clinical treatment options.
