多层螺旋CT在鼻科的应用价值

目的：回顾性分析行鼻内镜手术病例的多层螺旋CT资料，探讨多层螺旋CT对鼻内镜手术的指导意义。方法：对临床入院行鼻内镜手术的232例患者术前常规行多层螺旋CT扫描，并行冠状位、矢状位、斜位重建。结果：多层螺旋CT能够很好地显示和诊断鼻腔鼻窦疾病，尤其对窦口鼻窦复合体、额窦引流通道等复杂精细结构能够清晰显示，所有病例多层螺旋CT表现与鼻内镜检查及术中所见一致。结论：多层螺旋CT具有扫描时间短、患者接受射线剂量少、可任意多平面多角度成像、显示复杂结构清晰精细．对鼻内镜手术有积极的指导意义．可作为鼻内镜手术前的常规检查。

Application of Multi-slice Spiral Computed Tomographic Scan in Rhinology

Objective To evaluate the value of multi-slice spiral CT in nasal endoscopic surgery.Methods The multi-slice spiral CT data of 232 patients who were scanned prior to nasal endosopic surgery were analyzed.Results The nasal and sinus disease could be diagnosed correctly with multi-slice spiral CT.The ostiomeatal complex and the channels of the frontal sinus' drainage could be showed clearly.All the manifestation of the multi-slice spiral CT was in correspondence with the endoscopy showed in the surgery.Conclusion The multi-slice CT has the advantages of short scan time,less radiation dosage and multiplanar reconstruction.So it can display the nasal and sinus structures in detail,and has a great value in guiding the nasal endoscopic surgery.
