PDF: Management of Oro-antral Communication and Fistula: Various Surgical Options


Oro-antral communication and fistula can occur as a result of inadequate and improper treatment. Inadvertent communication with the maxillary sinus can occur during certain surgical procedures in the maxillary posterior region. 



Though, spontaneous healing may occur in defects which are smaller than 2 mm but larger communications require immediate attention and should be treated without delay, in order to avoid sinusitis and further complications leading to patient discomfort.


Oro-antral communications and fistulas (OACs & OAFs) are complications frequently encountered by oral and maxillofacial surgeons. Oro-antral communication is an unnatural communication between the oral cavity and the maxillary sinus.

These complications occur most commonly during extraction of upper molar and premolar teeth (48%). The major reason is the anatomic proximity or projection of the roots within the maxillary sinus.
