title: Maxillary sinus perforation with presence of an antral pseudocyst, repaired with platelet rich fibrin.
abstract: The maxillary sinus lifting procedure is an important preprosthetic surgical procedure for the creation of adequate bone volume in the edentulous posterior maxilla for the placement of dental implants. The presence of a maxillary sinus cyst has been considered a contraindication for this operation. Perforation of the membrane and hence the elongation of the healing time for implant placement is the most common complication in this type of procedure. The purpose of the case is to show the safely repair of the large sinus perforation during the sinus lifting with presence of the antral pseudocyst. In this case, we present a patient who had a maxillary sinus lifting procedure in the presence of antral pseudocysts. No complications were seen during follow-up periods and all implants are functioning successfully. Platelet-rich fibrin may be used safely when large perforation occurs during the sinus lifting with the presence of an antral pseudocyst.
