This report describing the radiology of transsphenoidal hypophysectomy based on a review of 100 consecutive surgical procedures. Preoperative laminographic evaluation of the sphenoid sinus is an important aid in planning the most direct surgical approach to the pituitary. It is also useful in defining the many anatomic structures that may be injured inadvertently at the time of surgery. Intraoperative radiography or fluoroscopy is helpful in identifying the sella floor and as an aid in preventing loss of orientation within a capacious sinus. Various changes occur within the sphenoid sinus following surgery, some transient and others persistent. The surgical defect is usually difficult to identify on routine roentgenograms but is clearly visible on lateral laminography. A persistent soft tissue mass within the sinus is usually a manifestation of fascia and fat placed as a seal within the sinus.
本报告基于对连续100例经蝶窦垂体切除术的回顾，描述了该手术的放射学表现。术前蝶窦的体层摄影评估对于规划垂体最直接的手术入路具有重要辅助作用。它还有助于明确手术时可能意外损伤的许多解剖结构。术中放射摄影或荧光透视有助于识别蝶鞍底，并有助于防止在宽大的窦腔内迷失方向。手术后蝶窦内会出现各种变化，有些是短暂的，有些是持续的。手术缺损在常规X线片上通常难以识别，但在侧位体层摄影上清晰可见。窦腔内持续存在的软组织肿块通常是作为密封物置于窦内的筋膜和脂肪的表现。
