The radiology of transsphenoidal hypophysectomy: a review of 100 cases Rothman SL; Kier EL; Allen WE 3rdAJR Am J Roentgenol 1976[Oct]; 127 (4): 601-6This 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.|*Hypophysectomy[MESH]|Humans[MESH]|Radiography[MESH]|Sella Turcica/surgery[MESH]|Skull Neoplasms/surgery[MESH]|Sphenoid Sinus/*diagnostic imaging[MESH] |
