Summary

This study tests whether mecobalamin, a form of vitamin B12, can speed up healing of the nerve that controls the vocal cords after thyroid surgery. About 528 adults having open thyroid surgery will receive either mecobalamin or a placebo for several weeks. The goal is to see if the vitamin improves voice quality and reduces complications like hoarseness or coughing when drinking.
