Platelet gel in oral and maxillofacial surgery: a single-centre experience.

Blood Transfusion = Trasfusione Del Sangue
Andrea DominijanniMario Giudice

Abstract

Platelet gel is a blood product intended for non-transfusion, therapeutic purposes; it is produced by combining platelet concentrate with cryoprecipitate. Platelet gel stimulates tissue growth and is a key player in tissue regeneration. As an allogeneic product, platelet gel is obtained from the blood of a common type O blood donor, with a platelet count >200×10(3)/μL. Most of the beneficial effects of this product are due to the numerous growth factors (PDGF, TGF-β, IGF-1 and IGF-2, EGF, VEGF and FGF) contained in the alpha-granules of platelets. The aim of this study was to confirm that platelet gel is a valuable aid for the surgical repair of alveolar bone loss. Our study was carried out on 87 patients with inflammatory or dysembryoplastic osteolytic lesions >2 cm in diameter in jaw bones. For most patients the platelet gel was collected into a 450 mL bag and kept frozen at -40 °C until, whereas for a small group of patients the gel was prepared and activated in the sterile field of the operating theatre. All of our patients reported a decrease in painful symptoms immediately after surgery. Follow-up showed considerable acceleration of the healing processes in soft tissues and faster bone regeneration. Multicentre studies ar...Continue Reading
