Abstract

Bisphosphonate medications are widely prescribed for the treatment of osteoporosis and cancer metastases to bone. However, these medications are among a list of agents which are implicated in medication related osteonecrosis of the jaw (MRONJ). A variety of non-surgical and surgical approaches are indicated in the treatment of this condition, depending on disease severity.

Highlights

  • Medication related osteonecrosis of the jaw (MRONJ) is a condition that manifests as exposed, necrotic and non-healing jaw bone, in patients who have been treated with bisphosphonates, denosumab, chemotherapeutic agents, anti-angiogenic drugs, tyrosine kinase inhibitors, thalidomide and steroids [1,2,3,4]

Summary

Introduction

Medication related osteonecrosis of the jaw (MRONJ) is a condition that manifests as exposed, necrotic and non-healing jaw bone, in patients who have been treated with bisphosphonates, denosumab, chemotherapeutic agents, anti-angiogenic drugs, tyrosine kinase inhibitors, thalidomide and steroids [1,2,3,4]. Based on the staging and severity of the condition, MRONJ can be managed surgically and/or non-surgically [4]. The recommendations for surgical treatment of stage I and II MRONJ vary in the literature [8,9]. The aim of this case series is to present a surgical approach utilizing mylohyoid flap along with platelet rich fibrin (PRF) combined with antibiotics and chlorhexidine mouth wash to manage patients with stage II and advanced stage I MRONJ.
