 Abstract
Oroantral fistula (OAF), also termed oroantral communication, is an abnormal condition in which there is a communicating tract between the maxillary sinus and the oral cavity. The most common causes of this pathological communication are known to be dental implant surgery and extraction of posterior maxillary teeth. The purpose of this article is to describe OAF; introduce the approach algorithm for the treatment of OAF; and review the fundamental surgical techniques for fistula closure with their advantages and disadvantages. The author included a thorough review of the previous studies acquired from the PubMed database. Based on this review, this article presents cases of OAF patients treated with buccal flap, buccal fat pad (BFP), and palatal rotational flap techniques.
Keywords: Oroantral fistula, Buccal flap, Buccal fat pad, Palatal rotational flap
