Abstract
PURPOSE: Bisphosphonate drug therapy provides benefits in the case of osteoporosis and carcinomas metastasizing to the bones, but it exposes patients to important side effects. The aim of this study was to investigate the incidence and the appropriate surgical treatment of bone lesions and fractures due to antiresorptive drug-related osteonecrosis of the jaws (ARONJ). METHODS: Patients presenting with osteonecrosis lesions of the jaw, who were referred to the Maxillo-Facial unit of the University of L'Aquila, were considered for inclusion. Grade of the lesion and treatment choice was recorded for each patient. Descriptive statistics were calculated and the data were analysed with Chi-squared tests. A representative case of a fracture reduction with a supra-periostal approach is reported. RESULTS: Among the 165 patients with ARONJ lesions, 112 were female and 53 were male. In total, 115 patients received intra-venous bisphosphonate therapy and 50 received oral bisphosphonate therapy. Five stage 2 lesions, three stage 2 lesions and two stage 3 lesions were not a consequence of dental procedures. Eighteen surgical bone excisions were performed and four pathological fractures were reduced. In one case (the reported one), the combined use of platelet-rich plasma and the supra-periostal approach leads to a successful 1-year follow-up. CONCLUSIONS: ARONJ lesions are a type of pathological bone disease affecting the jawbones. The pathology pathway remains a controversial and frequently discussed topic. A surgically conservative strategy seems to be the best way to assure a comfortable quality of life to those patients negatively affected by this condition.
