An oroantral fistula is an abnormal communication or opening that forms between the oral cavity (mouth) and the maxillary sinus. The maxillary sinus is a hollow space located in the upper jaw, just above the molar and premolar teeth. An oroantral fistula can develop as a result of various factors, most commonly due to complications arising from dental procedures or infections.

If the roots of these teeth are located close to the maxillary sinus, there is a risk of creating a communication between the oral cavity and the sinus during extraction. - Infections: Infections in the upper back teeth, especially with abscess formation, can erode the bone separating the oral cavity and the maxillary sinus, leading to the formation of a fistula. - Trauma: Trauma to the upper jaw, such
