Management of aggressive and extensive benign mandibular lesions by resection, curettage, freezing, and reimplantation of involved segment.

OBJECTIVE

The aim of this study was to evaluate the clinical outcomes of treatment of aggressive and extensive benign mandibular lesions by resection, curettage, freezing, and reimplantation of involved segments.

STUDY

DESIGN

In 9 patients with extensive, recurrent, and aggressive mandibular lesions, reimplantation of resected segment after immersing in liquid nitrogen was done.

RESULTS

After ≥18 months' follow-up, out of the 9 patients, one developed wound dehiscence that healed with conservative management and another local abscess and subsequent pathologic fracture that was treated by open reduction and internal fixation. No recurrence was found within the follow-up period.

CONCLUSIONS

Our study showed that management of aggressive lesions of the mandible by this method decreases the recurrence rate and eliminates the requirement of another operation for harvesting bone graft and reconstruction.
