Purpose There is no consensus on how to successfully treat medication-related osteonecrosis of the jaws (MRONJ). We report here on the application of piezoelectric bone surgery to treat MRONJ in combination with antibiotherapy and on its possible benefit.Materiel and methods A cohort of 18 consecutive patients has been treated for MRONJ; they involved 20 sites, 15 in the mandible, and five in the maxilla. Surgical removal of the necrotic areas and debridement was performed with a powerful piezoelectric surgery device (max 90 W) in combination with antibiotherapy. Results All patients healed and obtained a complete soft tissue closure within 1 month. No recurrence of the symptoms was observed during the present follow-up (10–54 months). Conclusion We hypothesize that healing of all treated sites might have resulted from the synergic effect of bone ablation, biofilm alteration, and antibiotic administration. Biofilm alteration might have permitted a better access of antibiotics to the involved germs. These encouraging results warrant further studies on the use of ultrasonic surgery to treat MRONJ patients in order to confirm or refute the hypothesized effect.

Abstract

Purpose There is no consensus on how to successfully treat medication-related osteonecrosis of the jaws (MRONJ). We report here on the application of piezoelectric bone surgery to treat MRONJ in combination with antibiotherapy and on its possible benefit.Materiel and methods A cohort of 18 consecutive patients has been treated for MRONJ; they involved 20 sites, 15 in the mandible, and five in the maxilla. Surgical removal of the necrotic areas and debridement was performed with a powerful piezoelectric surgery device (max 90 W) in combination with antibiotherapy. Results All patients healed and obtained a complete soft tissue closure within 1 month. No recurrence of the symptoms was observed during the present follow-up (10–54 months). Conclusion We hypothesize that healing of all treated sites might have resulted from the synergic effect of bone ablation, biofilm alteration, and antibiotic administration. Biofilm alteration might have permitted a better access of antibiotics to the involved germs. These encouraging results warrant further studies on the use of ultrasonic surgery to treat MRONJ patients in order to confirm or refute the hypothesized effect.
