Abstract (original English)

The formation of an oroantral communication (OAC) or fistula (OAF) is a rare complication resulting from the presence of processes in the lateral parts of the maxilla or for iatrogenic reasons. The most common causes of OAC or OAF are tooth extraction with periapical lesions. The aims of this systematic review were to assess the use of platelet-derived preparations rich in growth factors in the treatment of OAC or OAF, to determine the success of treating the communication or fistula, as well as impact on postoperative complications and the course of healing. The study was performed following PRISMA guidelines (PROSPERO: CRD42024570758). The inclusion criteria were as follows: at least ten patients, the presence of oroantral communication or oroantral fistula, treatment with platelet-derived preparations rich in growth factors, and information regarding the response to treatment. In order to find relevant studies, international databases, including PubMed, Google Scholar, Web of Science Core Collection, MDPI, Wiley, and Cochrane Library were searched. The last search was performed on 31 August 2024. Seven articles were included in the systematic review. In total, platelet-derived preparations rich in growth factors were used in 164 patients. Only studies in which OAC was treated and with platelet-rich fibrin (PRF) met the inclusion criteria. Only PRF was used as the sole treatm
