The aim of this study was to understand the global trends in the proliferation of various minimal invasive approaches including the endonasal endoscopic approach (EEA) and the extended EEA. Questions about the use of the supraorbital and transorbital approach were also included. ⋯ Our survey highlights the various geographic and demographic trends in the use of the EEA for sellar, suprasellar, and parasellar diseases. Although EEA training was present in almost all countries, the approach was not used as frequently as would have been expected for giant adenomas, craniopharyngiomas, and chordomas. After 20 years of education about the technique and indications of the endoscopic endonasal approach, through countless courses and publications, the use of EEA is still lagging, particularly in developing countries.
