Using nasoseptal flap(NSF) or not, for sellar reconstruction in extended endoscopic endonasal approaches for macroadenomas depends on pattern of suprasellar extension. Case 1- NSF was used where adenoma had horizontal extension over the planum sphenoidale and diapgragmatic defect (DD)>1cm. Case 2: Adenoma with no planum extension however was compressing the third ventricle floor-ACA complex where the DD<1cm; dual suction technique was used for intra-arachnoidal extracaopsular resection and was followed by multilayer modified reconstruction without NSF.
