Abstract
We experienced two cases of impaired vocal fold movement which occurred due to laryngeal trauma. At first, these cases were treated by thyroplasty. However, a sufficient improvement in the voice was not obtained. As a result, we operated on these cases using a special technique that is similar to a frontlateral laryngectomy which is generally performed on cases of laryngeal carcinoma. We show the method as follows. First, we removed the scar tissue. Next, we made a flap of skin and strup mascle in order to reconstruct the new vocal folds. The voice improved after operation, especially regarding the maximum phonation time. This method is therefore considered to be very useful for unilateral vocal fold impairment due to chronic laryngeal trauma.
