| Abstract;Background: It is well known that surgical treatment for sulcus vocalis is extremely difficult; however, intracodal injection is one method for creating new free edges of a vocal fold by augmentation. Here, we report in detail good results achieved using autogenous fat as the injection material. We also discuss an additional approach for treating the sulcus itself. Method: Two subjects with sulcus vocalis were treated with intracordal injections of autogenous fat harvested by suction from the abdominal wall. Voice production was evaluated prior to injection and at intervals after injection. Results: Voice improved not only subjectively but also objectively. Discussion: A major disadvantage of this method is that lasting effectiveness is rather limited due to the absorption of fat after injection, so transplantation also should be considered. Moreover, a potential direct approach for treating the sulcus itself includes resectioning of the sulcus and medicating with Tranilast, which our experimental findings showed contribute to further voice improvement. Conclusions: Although we attained moderate improvement of phonation by autogenous fat injection, we conclude that resectioning of the sulcus and use of Tranilast as a direct approach for treating the sulcus itself might contribute to greater voice improvement.
