The Role of Autologous Platelet Concentrates in the Treatment of Medication-Related Osteonecrosis of the Jaw

Abstract The frequent refractory response of patients to the treatment of medication-related osteonecrosis of the jaw (MRJON) has attracted clinicians’ attention to several treatments. However, they are at best, palliative, and have a higher failure rate than previous treatments. The present meta-analysis was performed to evaluate the clinical effectiveness of autologous platelet concentrates (APCs) combined with surgery in the treatment of MRONJ. The authors conducted a meta-analysis involving a systematic search of PubMed, EMBASE, Wiley Online Library and the Cochrane Library for eligible studies from their inception to November 2019, in accordance with preselected criteria. The inverse variance method was applied to fixed or random effects models based on the heterogeneity of the studies. Thirteen studies that investigated APCs in the treatment of MRONJ were eligible for inclusion in the meta-analysis of 223 patients and 33 lesions. The pooled success rate of APCs combined with surgery for MRONJ was 90% (95%CI, 80%–97%) and the pooled OR was 7.67 (95%CI, 2.10–27.98), indicating the combination was 7.67 times more effective than surgery alone. The results suggest that the use of APCs is a promising therapeutic regimen, as it provided additional benefits to surgery in the treatment of MRONJ. To achieve the benefits, a tension-free primary closure of the soft tissue is recommended as well. Randomized studies with large sample sizes is warranted to confirm our finding.
