Review Of Oro-Antral Fistula

Oroantral communication is the space created between the maxillary sinus and the oral cavity which if not treated will progress to oroantral fistula. This post-extraction complication occurs more if there is pre-existing periapical pathology associated with the offending tooth near the maxillary sinus or extraction of such maxillary molar teeth with widely divergent roots. Many procedures have been used for closing oroantral fistula. These have ranged from simple local flaps to more complex distant flaps and even closure with alloplastic materials. In this book we have tried to cover most of the treatment alternatives that will prevent and help in treating the complication.
