Abstract:
Objective To explore the clinical application and to evaluate the value of multi-slice spiral computed tomography (MSCT) in closed thyroid cartilage injury.Methods MSCT Scan was performed in 5 patients with closed thyroid cartilage injury,and 2D and 3D images reconstructions were achieved after volumn data was transferred to workstation.Results In 5 cases,the thyroid cartilage fracturewas found in left board in 4 patients.in right board in 1 patient.In addition.one patient had concurrent cricoid cartilage fracture and another patient had laryngotracheal stenosis.These fractures and changes were all visualized by 2D and 3D images.Lower window level and window width were helpful to reveal the structures of thyroid cartilage.Multi-planar reconstruction (MPR) Was superior in displaying alignment and displacement of fracture in 4 cases.3D-volume reconstruction (3D-VR) was accurate in displaying space change of cartilage structures.In 3 cases,the evaluation of 3D-VR was accurate in assessing the length,width and shape of fracture,providing helpful data for the clinician to adopt the optimal management.Computed tomography virtual laryngoscope (CTVL) helped to offer the criterions to the diagnosis of upper airway stricture and the location of laryngotraeheal stenosis in one case.Conclusions MSCT was useful in the diagnosis and management of closed thyroid cartilage injury and the laryngotracheal stenosis.It was believed that the reasonable use of the reprocessing technique plays an important role in the diagnosis,treatment and evaluation of the effect of closed thyroid cartilage injury.
