Sinus ventilation due to accessory ostia
There is an anceint saying "A room of many doors will be windy, a person of many works (talkative) will bring disaster". Can this saying be applicable to special cases of maxillary sinus with accessary ostia? Tppically a sinus only has one opening, known as ostium. The air, mucus, can only enter and discharge via this single opening. However, for some, the sinus may have multiple openings, known as accessory ostium. In the work below, we use computaitonal fluid dynamics to examine the effect.
