Oroantral fistula (OAF) is an abnormal connection between the oral cavity and the maxillary sinuses. This pathology develops when the oroantral communicant fails to close spontaneously; thus, it remains patent and epithelialized. If not treated immediately, this condition might be the passage for bacteria to enter the maxillary sinuses, causing infection, sinusitis, or delayed healing. Consideration of OAF therapy should consider the width of the defect, epithelialization, and whether or not there is an infection. This article aims to understand oroantral fistula and learn about the management of this case so that it can be applied scientifically in medical practice.
