MASSIVE RADICULAR CYST IN THE MAXILLARY SINUS, CASE REPORT
Fares Al Rawashdeh*
ABSTRACT
The radicular cyst is the most common cyst of the oral and maxillofacial region. It is usually caused by pulpal
necrosis which is secondary to trauma or dental caries. The radicular cyst is usually asymptomatic, but a secondary
infection can occur and cause pain. Radicular cyst is also known as periapical cyst, apical periodontal cyst or
dental cyst. On radiographs, it appears as radiolucency around the apex of a tooth's root. These cysts may persist
even after extraction of offending tooth; these cysts are called residual cysts. The vast majority of the radicular
cysts are small, but they can reach a large and even a massive size. In such cases, the cyst may cause displacement
of the surrounding structures. In the posterior part of the maxilla, a massive radicular cyst can cause displacement
of the floor of maxillary sinus. In this situation, a careful review of plain radiographs and/or CT images is
necessary to determine the origin of the lesion, whether it is from the maxillary sinus or from the maxilla. This
article reports the case of a massive radicular cyst that caused displacement the floor of the maxillary sinus, the
diagnostic approach and the surgical intervention. The article had been given the approval of the ethical committee
of the hospital and an informed consent of the patient was taken.
