An oro‐antral communication is an unnatural opening between the oral cavity and maxillary sinus. When it fails to close spontaneously, it remains patent and is epithelialized to develop into an oro‐antral fistula. Various surgical and non‐surgical techniques have been used for treating the condition. Surgical procedures include flaps, grafts and other techniques like re‐implantation of third molars. Non‐surgical techniques include allogenic materials and xenografts. This is an update of a review first published in May 2016.
