目的 探讨蝶鞍区CT三维重建在经单鼻孔蝶窦入路垂体瘤切除术中的作用.方法 应用多层螺旋CT和AQI影像工作站对54例垂体瘤患者术前进行蝶鞍区CT薄层扫描、三维重建,观察蝶窦气化类型、分隔情况、蝶窦与鞍底的关系,并与术中实际情况进行对比验证.结果 蝶窦双侧气化程度相同者24例,气化不同者30例.蝶窦分隔呈正中矢状位者14例;偏左者15例;偏右者19例;其他类型(包括不同程度斜位,横位等)6例.蝶窦位于鞍底中线之前者12例,蝶窦位于鞍底中线下方者32例,蝶窦位于鞍底中线之后者10例.结论 蝶鞍区CT三维重建可简单、直观、准确的反映每例患者蝶窦形态及其与周围毗邻结构的关系.为术者提供更加完整和实用的影像学信息.
目的 探討蝶鞍區CT三維重建在經單鼻孔蝶竇入路垂體瘤切除術中的作用.方法 應用多層螺鏇CT和AQI影像工作站對54例垂體瘤患者術前進行蝶鞍區CT薄層掃描、三維重建,觀察蝶竇氣化類型、分隔情況、蝶竇與鞍底的關繫,併與術中實際情況進行對比驗證.結果 蝶竇雙側氣化程度相同者24例,氣化不同者30例.蝶竇分隔呈正中矢狀位者14例;偏左者15例;偏右者19例;其他類型(包括不同程度斜位,橫位等)6例.蝶竇位于鞍底中線之前者12例,蝶竇位于鞍底中線下方者32例,蝶竇位于鞍底中線之後者10例.結論 蝶鞍區CT三維重建可簡單、直觀、準確的反映每例患者蝶竇形態及其與週圍毗鄰結構的關繫.為術者提供更加完整和實用的影像學信息.

Objective To study the significance of three dimensional reconstruction of CT scan of the sellar region in transsphenoidal microsurgery for pituitary adenoma.Methods Multi - slice spiral CT scan and three dimensional reconstruction and AQI image workstation were used in 54 patients with pituitary adenoma.The pneumatization classification and septum of sphenoid sinus,image data were further proved and compared with the real anatomy of sphenoidal sinuses during the microneurosurgical procedure.Results The sphenoid sinuses were found to be identical type of pneumatization in 24 cases and non identical in 30 cases. According to the vertical line drawed from the central point of the sella floor,the septums of sphenoidal sinus were located in midline in 14 cases,in left side in 15 cases,in right side in 9 cases.Transverse - or oblique - oriented septums were found in 6 cases.Classification of sphenoidal sinus were established according to the vertical line drawed from the central point of the sella floor to Nassion line,and the sphenoid sinuses were located in front of the vertical line in 12 cases,under the vertical line in 32 cases,and behind of the vertical line in 10 cases. There was statistical variation in individual.Conclusions The three dimensional reconstruction of CT scan can accurately show the shape and adjacent structures of sphenoidal sinus and aid in transsphenoidal microsurgery for pituitary adenoma.
