Management of locally aggressive mandibular tumours using a gas combination cryosurgery.

This study evaluated the results of curettage followed by cryosurgery using a combination of propane, butane, and isobutane gas for several benign but locally aggressive bone tumours on the mandible. Twenty-nine patients (16 men and 13 women) participated in the study. Patient ages ranged from 6 to 87 years (mean, 23.72 years). Before enucleation and cryosurgery, some patients received prior treatment consisting of marsupialisation to decrease tumour size. Twenty-seven of the 29 patients (93.10%) showed no evidence of clinical or radiographic recurrence after treatment through enucleation and cryosurgery. Wound dehiscence, which was observed in all cases, healed by second intention. The average follow-up period was 70.55 months (range, 53-120 months). These results suggest that enucleation followed by cryosurgery is an effective therapy for managing locally aggressive mandible tumours. In addition, this treatment is a less expensive intervention than more radical procedures.
