Migration of a foreign body in the maxillary sinus illustrating natural mucociliary action.
We present a case of a foreign body which migrated to the maxillary ostia by mucociliary action from its initial location on the floor of the maxillary sinus where it was traumatically introduced. This report illustrates that a powerful mechanism of mucociliary action can cause relatively heavy objects within the maxillary sinus to migrate naturally to the sinus ostia against gravitational force.
