Abstract

INTRODUCTION:

There is currently no gold standard for the treatment of Stage III bisphosphonate-related osteonecrosis of the jaw (BRONJ). The question remains whether osseous reconstruction can offer an additional gain in outcome given the theoretical risk of non-union at the resection margins and recurrence in the osseous free flap. The objective was to conduct a systematic review of articles describing outcomes of osseous microsurgical reconstruction in cases of BRONJ with a minimum follow-up of 12 months, and to present the long-term outcomes of a new case series of three patients.

MATERIAL AND METHODS:

A multi-database QUORUM-based single-reviewer systematic review identified eight papers that fulfilled the selection criteria. There are only case series and case reports available (Level 4 of the Oxford Evidence-based medicine scale). A total of 31 patients were analysed including the cases described in this article.

CONCLUSION:

The limited overall rate of non-union at the resection margins and the 6.5% recurrence rate of BRONJ in the transplant counters the theoretical objections and advocates for considering osseous free flap reconstruction in the treatment of refractory BRONJ Stage III lesions. However, additional data derived from larger case series or case-control studies are imperative to support this hypothesis.
