Summary

This study tested a surgery that reconnects nerves in the throat to help people with both vocal cords paralyzed. The goal was to improve breathing and voice without causing swallowing problems. Four adults who had not gotten good results from earlier treatments took part. Results took 6 to 9 months to appear, and some needed a follow-up procedure for voice improvement.
