Medication-Related Osteonecrosis of the Jaw: evaluation of a therapeutic strategy in oral surgery.
Journal of Stomatology, Oral and Maxillofacial Surgery 2024 April 18
BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is a severe adverse illness linked to antiresorptive therapies (ART), for which there is no therapeutic gold standard. Many factors can influence MRONJ evolution such as cancer type, treatment, comorbidities, and accumulated dose of ART. The aim of this study was to determine the influencing factors of MRONJ treatments success.
METHODS: This retrospective study focused on patients treated for MRONJ in a French tertiary centre. Non-operative therapy was always applied, ART were suspended if appropriate, and surgery (MRONJ removal and musculo-mucosal flap reconstruction) was performed in the absence of contraindication. The evaluation criteria were bone and mucosal healing 3 months after surgery.
RESULTS: 81 MRONJ were included; medical treatment alone was administered to 26% while the remaining 74% received additional surgery. Therapeutic success reached 86.7% (52/60) for surgery compared to 42.9% (9/21) for medical treatment alone (p<0.001). Age (OR=1.08, p=0.014) and the absence of infection (OR=5.32, p=0.042) were in favour of success, while medical treatment alone (OR=0.03, p<0.001) was highly unfavourable.
CONCLUSION: MRONJ healing is influenced by age, non-infectious stages, and surgery. Additional surgery in MRONJ treatment should be advised if the health of the patient permits.
