Intralesional injection of triamcinolone hexacetonide as an alternative treatment for central giant cell lesions: a...

The aim of this prospective study was to report on the response to treatment of central giant cell lesions (CGCL) with intralesional corticosteroid injections. Consecutive cases of CGCL were treated with a biweekly intralesional injection of 20mg/ml triamcinolone hexacetonide diluted in an anaesthetic solution of 2% lidocaine/epinephrine 1:200 000 at the proportion 1:1. All patients were monitored using cone beam computed tomography. Eleven patients were treated; their ages ranged from 15-34 (mean 22 years); and eight lesions were in the mandible, and three in the maxilla. Three cases were diagnosed as non-aggressive, and eight as aggressive. Six cases presented good results (four aggressive and two non-aggressive); three cases presented a moderate response (two aggressive and one non-aggressive); and two had a poor response to treatment (both aggressive). In four cases with a good response, osteoplasty was done. In all cases with a moderate response, the remaining lesion was curetted. Cases with a poor response were submitted to either curettage or denosumab injections. Corticotherapy, as main or neoadjuvant therapy, may be an option for treatment of CGCL.
