REHABILITATION OF CENTRAL GIANT CELL GRANULOMA WITH ILIAC GREFT AND REMOVABLE SPACE MAINTAINER: CASE REPORT

Purpose: central giant cell granuloma is a nonodontogenic pathological lesion that usually located in the mandible and maxilla. the aetiology of giant cell granuloma is undefined. surgical removal is the most commonly applied therapy. our aim was to report rehabilitation of central giant cell granuloma with iliac graft and removable space maintainer. case report: a 10-years-old child was referred to our clinic complaining of swelling in the mandibular anterior region. the parents of the patient were reported that a surgical operation was done in mandibular anterior region of the patient one year ago. they also reported that this lesion was recurred six months after first surgery. the recurred lesion was removed under general anesthesia, mandibular left central, lateral, canine and first premolar teeth were extracted. iliac crest graft was harvested and fixed to the mandible. the histopathology report confirms the diagnosis of a central giant cell granuloma. the patient's postoperative 12 months follow-up exam was uneventful. the patient was referred for removable space maintainer. conclusion: aggressive lesions such as central giant cell granuloma observed 72% recurrence rate to the literature. conservative methods such as corticosteroid injection, systemic calcitonin’s success isn’t definite on the recurred lesion. the surgical treatment may cause major defects in jaw bones and changes the facial contours, the repair of the defect with iliac bone graft was performed to solve aesthetic problems and facilitate the further prosthetic rehabilitation.
