Closure of Oroantral Communication with Gelfoam and Collagen Membrane after Periapical Cyst Enucleation-A Case Report

Abstract

Periapical cyst is the most common inflammatory cyst that occurs in jaw bones. Epithelial cell rests of Malassez in periodontal ligaments are the main cause for the periapical cysts to be formed. Periapical cyst occurs commonly in infected and necrotic periapical area, with male sex predilection and occurs, especially in the 3rd to 6th decades of life. Non vital tooth left untreated for long time predisposes to periapical cyst formation. Oroantral Communication (OAC) is one of the most routinely encountered complications during surgical procedure by oral and maxillofacial surgeons when attempting to remove a cyst from maxilla. Oroantral communication is the abnormal, pathologic, unnatural open connection between the oral cavity and maxillary sinus. If such a communication remains open it can cause ingress of microorganisms from the oral cavity into the antrum resulting in maxillary sinusitis, and develops into an Oroantral Fistula (OAF). Hereby, authors presented a case report of a 32-year-old female patient with the complaint of pain and swelling in relation to the left upper back tooth region. The gelfoam and collagen membrane were used to close an oroantral communication, which was developed after periapical cyst enucleation.
