Comunicação buco-sinusal: diagnóstico, complicações e tratamentos – revisão de literatura

Abstract

The oroantral communication is the direct access between the maxillary sinus and the oral cavity. It may be caused by pathologies, traumas or dental extractions of posterior upper elements. Its diagnosis must be made through anamnesis, image exams and clinical exams, including the Valsalva Maneuver. Even though it is already considered a complication, oroantral communication, if not treated, can progress to an oroantral fistula or maxillary sinusitis. Treatments vary according to the size of the communication, timing of diagnosis, presence of infection and experience of the dental surgeon, it may be just medication or surgery, if necessary. The aim of this study is to review the literature about oroantral communication, addressing topics such as anatomy of the maxillary sinus, diagnosis, complications and treatments. The literature review was based on articles from 2000 to 2021, published in databases such as PubMed, EBSCO, Scielo and Google Scholar. It is possible to conclude that all treatments are effective, but prevention is always extremely important, requiring good planning of the case
