CLOSURE OF FISTULA OROANTRAL CAUSED BY A MAXILLARY EXTENDED RADICULAR CYST USING A PALATAL CONNECTIVE TISSUE GRAFT: A CASE REPORT (Abstract): Radicular or periapical cysts are the most common inflammatory cysts of the maxilla. Because of cancellous bone of the maxilla it is easier for lesion to occupy the bone space and extend to surrounding anatomical structures such as the maxillary sinus, occupying it and reducing it to a small cavity. Cyst infection is the most frequent complication. Intraosseous suppuration can open spontaneously, causing a fistula. The purpose of this case report is to present the surgical treatment of a periapical cyst of very large size, which encompassed the maxillary sinus and extended to the floor of nasal fossae, determining the occurrence of a chronic fistula. Original features of this case are the large extension of the lesion, the obtaining of a sufficient spontaneous bone regeneration without the use of bone graft material due to the young age of the patient and good health, absence of nerve lesions after surgery for total removal of the cyst and persistent fistula closure with a palatal connective tissue graft. The healing went without any special events. In spite of the large dimensions of radicular cyst there were no complications, the connective tissue graft was accepted and the color of tissue was homogeneous.
