[1] The creation of an OAC is most commonly due to the extraction of a maxillary tooth (typically a maxillary first molar) which is closely related to the antral floor.
Variations of the maneuver can be used either in medical examination as a test of cardiac function and autonomic nervous control of the heart, or to clear the ears and sinuses (that is, to equalize pressure between them) when ambient pressure changes, as in scuba diving, hyperbaric oxygen therapy, or air travel.
Those that are larger than 2mm have a higher chance of developing into oro-antral fistula (OAF). [11] The passage is only defined as an OAF if it is persistent and lined by epithelium. [11] Epithelialisation happens when an OAC persist for at least 2–3 days and oral epithelial cells proliferate to line the defect.
