Abstract
Aim. Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a well-known potential complication of bisphosphonates (BPs) therapy and its treatment could reckon on different approaches. Recently, encouraging results for BRONJ were showed from some clinical studies using Er, Cr: YSGG laser-assisted surgery. Platelet-Rich Plasma (PRP), a new approach to promote tissue regeneration and healing, may be a promising complementary therapy. The aim of this pilot study is to study the effectiveness, in terms of clinical healing, of a combined treatment (laserassisted surgery and topical PRP) for BRONJ in a group of cancer patients. Methods. Ten oncological patients (3 males, 7 females; aged 69-89 years, mean age 76.2±5.8) with BRONJ were consecutively recruited. BRONJ was classified (T0) according to. All patients underwent pre- and peri-operatory antibiotic prophylaxis, and preparation of autologous PRP; the following combined surgical protocol was applied: i) exposure of the surgical area, through the creation of surgical edges; ii) courettage of the necrotic bone and, if present, sequestrectomy, by using a Er, Cr: YSGG laser; iii) application of autologous PRP over the entire bone cavity; iiii) suture of surgical flaps. All patients performed a CT after 3 months from surgery (T1) in order to re-stage of the disease. Successful treatments were considered the complete healing and the radiological improvement (transition from a higher stage to a lower one). Results. At T0 6/10 patients were stage IB, 2/10 were stage IIA and 2/10 were stage IIB. At T1, 3/10 (30%) cases (2 cases IB and 1 case IIB) showed no clinical and radiological signs of BRONJ relapse; 5/10 (50%) cases (4 cases IB and 1 case IIB) showed clinical improvement, whereas 2/10 (20%) (both IIA) showed no-improvement. Conclusion. The association of laser-assisted surgery and topical PRP, firstly investigated in this study, seems useful in BRONJ healing among cancer patients. Further investigation is necessary in order to validate these preliminary results
