The ostium of frontal sinus Positions should be divided into two type by the interaction of basal lamella of bulla and cribriform roof. TypeⅠ: The ostium of frontal sinus is located in lateral sinus, flows through superiorsemilunar hiatus to middle nasal meatus. It is about 20%. TypeⅡ: The ostium of frontal sinus is located in ethmoid infundibulum, frontal recess and its cell, flows through interior semilunar hiatus to middle nasal meatus. It is about 80%. Among them there are about 62.5% in ethmoid infundibulum, about 37.5% in frontal recess.
