Long-term clinical and radiological outcomes of surgical management of central giant cell granuloma of the maxilla

Abstract

The aim of this study was to report the results of long-term clinical and radiological follow up of the surgical management of central giant cell granuloma of the maxilla. A retrospective analysis was conducted on 12 patients—5 male and 7 female whose ages ranged from 9 to 41 years, with central giant cell granuloma of the maxilla treated between 1991 and 2000. The anterior maxilla was involved in five cases, seven cases were in the posterior region, and none crossed the midline. Four patients were asymptomatic and eight patients presented with pain, mobility of teeth, and rapidly enlarging facial swelling. Radiographically, all lesions were radiolucent; 58.3% were unilocular, and the borders were well-defined in 33.3%. Roots were commonly displaced by the lesion, but no root resorption was observed. Cortical perforation was seen clinically and on CT scan in four patients. All cases were treated with thorough curettage until healthy bone was encountered. In cases with cortical perforation the affected buccal and/or palatal mucosa was excised. When the maxillary sinus was affected or the lesion was bulging into the nose, the nasal mucosa was also removed. All patients were reviewed annually for a follow-up period of 2–9 years; the condition recurred in two patients. It is concluded that thorough curettage is a satisfactory method for the treatment of non-aggressive and aggressive central giant cell granuloma of the maxilla, with a low recurrence rate and favorable postoperative outcome.
