Research Of Microsurgery Removing Sellar Region Tumor By Interhemispheric Approach (Reports Of 36 Cases)

Objective:To research the new interhemispheric approach treatments of removing different large or huge sellar region tumor. Methods :To remove 36 cases of different infiltrated-growth large or hugesellar region tumors by interhemispheric approach microsurgery Results:In 36 cases,including 23 cases pituitary tumorl;4 cases meningioma;6 cases craniopharyngioma; 2 cases gliomas and 1case chordoma .23 cases were performed by anterior interhemispheric approach;6 cases performed by unifrontal interhemispheric approach; 4 cases were performed by key-hole interhemispheric approach ;2 cases were performed by interhemispheric and transsubfrontal approach;1 cases were performed by unifrontal interhemispheric approach with endoscopic surgery. Total removal was achieved in 29cases,subtotal in 5 andmost-partly in 2,without any severe complications or dead cases.With 3 to 12 months follow-up of 14 cases,the vision and visual field were improved in 13cases,without changes or worsen in 1cases.12 in 18 functional pituitary adenoma were followed up,10 cases got recovery on hormone level,2 cases reduced obviously.2 cases recurred,both received γ-knife treatment. Conclusion: the new interhemispheric approach surgery are good treatment for large or huge invasive sellar region tumor...
