According to the extension of the disease, the transnasal endoscopic resection can be performed unilaterally [11, 12] or bilaterally. In the first case the resection will be extended anteroposteriorly from the posterior wall of the frontal sinus back to the planum sphenoidale and laterolaterally from the nasal septum to the lamina papyracea; in the second case the resection will be extended from one lamina papyracea to the opposite one. The step-by-step technique of endoscopic endonasal resection (EER) is summarized in six main surgical phases (Fig. 2).
