MARSUPIALIZATION OF LARGE MANBILULAR RESIDUAL CYSTS. TWO CASE REPORTS.

Introduction: Large residual cysts are relatively rare inflammatory cysts of the jaws. They derive from radicular cysts that had not been completely removed after dental extraction. In some cases, these lesions can grow large without any symptoms and they are discovered as incidental radiographic findings. Marsupialization is an alternative treatment for large cysts, avoiding significant complications such as nerve injury, jaw fracture, sinus or nasal perforation which can occur from curettage during enucleation. Case presentation: We present two different cases of male patients with mandibular residual cysts, who were referred to our department. Both patients presented with swelling and pyorrhea. The radiological examination revealed large well-defined lesions that had absorbed extensive jaw sites. The localization of both cysts was significantly close to the inferior alveolar nerve. Marsupialization and acrylic resin obturator placement was performed in both cases. The follow up period of 18 months from surgery is presented. Conclusion: In conclusion, marsupialization is a conservative, efficient surgical technique that promotes bone healing and the shrinkage of the existing lesion.
