Platelet‐rich plasma in treatment of scar, atrophy, and sulcus: Short‐ and long‐term results
Peak Woo
Abstract:ObjectivePlatelet‐rich plasma (PRP) is rich in growth factors and is easily obtained from blood samples. Long‐term data after PRP injection into the larynx should be improved. This study reports the short‐term (3 months) and long‐term (12 months) voice results after PRP injection.Materials and MethodsSixty‐three patients with scars (n = 34), sulcus vocalis (n = 17), recalcitrant nodules (n = 5), atrophy (n = 4), or a combination of these (n = 3) were included (158 injections; median follow‐up = 12.3 months).
