Fechamento de comunicações e fístulas buco sinusais: uma revisão de literatura

Abstract

Objective: To synthesize the available techniques for treatment and/or closure of oroantral communicantions/fistulas. Material andMethods: A research was performed in the data bases Pubmed, SciElo, Lilacs (Literatura Latino-americana e do Caribe em Ciências da Saúde), BBO (Bibliografia Brasileira de Odontologia) and Capes Periodicals, using the descriptors “odontology”, “oroantral fistula” and “sinusitis”. The terms cited were combined in pairs. The research period was from 2010 to 2020, and articles in the English and Portuguese languages. Review articles were excluded. Results: Oroantral communication (OAC) is the opening between the maxillary sinusand oral cavity. OAC acts as a pathological pathway for bacteria and can cause infection of the antrum, wich further obstructs the healing process. Small defects may close spontaneously, however, large oroantral defects generally require reconstruction. Although various techniques have been proposed in published studies, long-term successful of oroantral fistulas is still onde of the most difficult problems confronting the surgeon working in the oral and maxilla facial region. Conclusion: There are different ways to perform the surgical closure of the OAC. The decision-making in closure of aroantral communication and fistula is influenced by many factors. Consequently, it requires a combination of knowledge, experience and information gathering.
