[The surgical treatment of non-functioning pituitary adenomas in the ninth decade].

: There are no reports of surgical treatment for non-functioning pituitary adenomas in the 9th decade of life, and it is thought that these patients often select conservative treatment and observation, because of their worry about deterioration of their general condition due to invasive surgery and because hypopituitarism and other medical problems are often present. However, it is also true that there is necessity for considering surgical treatment for the pituitary adenomas even in the 9th decade when there is a complaint of visual disturbance. We carried out the palliative surgical removal of three non-functioning pituitary adenomas with visual disturbance in the 9th decade and report these surgical treatments and outcomes. The improvement of visual disturbance was obtained in all three cases. The only perioperative complication was pneumothorax caused by barotrauma. The palliative transsphenoidal surgical removal of non-functioning pituitary adenomas for the purpose of improvement of visual disturbance is a safe procedure in the 9th decade of life.
