oroantral การใช้

This term signifies pathology and it is not to be confused with Oroantral Communication ( OAC ).
The maxillary sinus may drain into the mouth via an abnormal opening, an oroantral fistula, a particular risk after tooth extraction.
Oroantral fistula ( OAF ) is an abnormal condition where the maxillary sinus is exposed to the oral cavity through an epithelialised fistula.
Other methods like radiographs ( occipitomental, OPG and periapical views ) can also be used to confirm the presence of any oroantral fistulas.
Observe if there is passage of air or bubbling of blood in the post extraction alveolus as the trapped air from closed nostrils is forced into the mouth through any oroantral communication.
