Diagnostic accuracy of computed tomography and magnetic resonance imaging compared to surgical exploration for anterior skull base and medial orbital wall infiltration in advanced sinonasal tumors

Background Knowledge of medial orbital wall (MOW) and anterior skull base (ASB) infiltration is of uttermost importance for staging and therapy planning of advanced sinonasal tumors. Methods We assessed the diagnostic performance of preoperative computed tomography (CT) and magnetic resonance imaging (MRI) for MOW and ASB infiltration compared to intraoperative exploration. Results Both CT and MRI yielded higher diagnostic accuracy for MOW...
