This patient suffered from a brain tumor. Brain surgery was performed, but her voice became hoarse due to paralysis of her left recurrent laryngeal nerve. We performed phonosurgery, arytenoid rotation operation (Isshiki), but improvement of the hoarseness was transient. We trained her voice with the pushing method. Gradually her hoarseness and maximum phonation time (MPT) improved. 1. Both phonosurgery and voice training were performed, and satisfactory results were obtained. 2. We introduced the treatment plan to improve hoarseness caused by unilateral recurrent laryngeal nerve paralysis. We also described the general outline of phonosurgery. We emphasized the importance of voice training to be performed along with phonosurgery. 3. We studied the use of computer acoustic analysis as a means of objectively evaluating improvement on voice hoarseness by various treatment methods.
