Intrafold Injection Considering the Cause of Disease

Abstract

Since adjuvant disease related to silicone was reported, the indication of intrafold silicone injection for the patients with unilateral recurrent laryngeal nerve paralysis (ULRLNP) has been re-considered. In particular, the autologous fat injection technique has been reported as a safe method, and this procedure is now carried out frequently in Japan. In the present study, we compared the results of sillicone injection in 349 cases with the results of fat injection in 18 cases and found that postoperative voice function was excellent in both methods. In addition, no patients suffered from adjuvant disease in either group. Although intrafold autologous fat injection is a less invasive and safe alternative method for patients with ULRLNP, this procedure is not practical in thin patients. Our results indicate that percutaneous intrafold silicone injection is a usuful therapy for ULRLNP terminal patients, such as those with esophageal or lung cancer.
