CBCT Anatomy Flashcards
what is the opening from the maxillary sinus to the nasal cavity called
ostium
where do posterior ethmoidal cells drain
to the superior meatus
where does the sphenoid sinus drain
the superior meatus trough the sphenoethmoidal recessw
where does the frontal sinus drain
middle meatus through frontal recess
where do anterior ethmoid air cells drain
mostly to the ethmoid bulla
