Paranasal sinus agenesis is an unusual clinical condition. The frontal sinus agenesis is more frequently seen, whereas agenesis of the sphenoid sinus is extremely rare. This report presents three new cases of sphenoid sinus agenesis. The absence of the sphenoid sinus was demonstrated by computed tomography (CT) in all cases.
