Rare mandibular condylar pathology and new surgical approach: intraoral approach for resection and reconstruction of aneurysmal bone cyst, a case report

Abstract

The case of a 27-year-old male with a destructive aneurysmal bone cyst of the right mandibular condyle, coronoid process and ascending ramus is presented. Surgery revealed an eggshell-thin, partly perforated cortices. Intraoral approach was used for a complete resection of mandibular condyle, coronoid process and affected ascending mandibular ramus. Curettage of the adjacent soft tissues performed; no extra oral incision was used. In this case following resection, the defect was primarily reconstructed with prefabricated reconstruction plate with condylar head to maintain functional mandibular ramus height, avoid malocclusion and asymmetry. Post-operative examination and radiographic images revealed good symmetry and perfect occlusion as well as almost normal mandibular function. Intraoral approach can be used to access to the mandibular condyle region and ascending ramus with no risk to facial nerve and skin scar so cosmetically more favorable.
