Abstract | BACKGROUND: High-definition imaging in endoscopic transsphenoidal pituitary surgery accounts for significantly better identification of anatomic structures. This report presents the clinical images of the adenohypophysis and neurohypophysis under high-definition endoscopic observation, and provides some clues for pituitary-sparing surgery. METHODS: RESULTS: The extracted findings contain the following lessons: (1) to find a boundary plane that separate a lesion from the pituitary; (2) to mark the difference of color between the adenohypophysis and the neurohypophysis; (3) to identify the location of the pituitary stalk connecting to the neurohypophysis; (4) to observe the color change of the pituitary induced by decompression; (5) to know pathological findings of the pituitary surface; (6) to distinguish the parenchyma of the neurohypophysis from pathological tissues; and (7) to recognize the intrasellar findings at the completion of removal. Recognition of these findings led to an excellent result in each case. CONCLUSIONS: Despite being shown in a limited number of cases, on the basis of HD endoscopic images, accurate identification of the neurohypophysis and the pituitary stalk as well as adenohypophysis during surgery contributes to pituitary-conserving operations.
