The maxillary sinuses, as well as the other paranasal sinuses, help in the resonance of the voice, improve the inspired air, reduce the weight of the skull and balance the differences in pressure. They are also an immunological barrier through the production of lysozyme. Oroantral communications between the oral cavity and the maxillary sinuses, are rare complications of oral surgery. The extraction of posterior maxillary teeth is the most common cause of these complications due to the anatomical relationship between the apexes of the premolars and molars and maxillary sinuses. Oroantral fistulas are pathological connections between the maxillary sinus and the oral cavity, lined by epithelium. The choice of the appropriate therapy should consider age, gender, race, width of the fistula, presence or absence of sinus infections and local or systemic pathologies. The appropriate management should be maintained until the closure of the oroantral fistula and the elimination of the sinus infection to ensure a good healing and to prevent recurrences. Through a review of literature (books and articles) I intend to explore the oroantral fistula treatments, further illustrated using clinical cases from the University clinic, resolved surgically by our Faculty Professors of Oral Surgery.
