Analysis of long-term voice changes post-thyroidectomy indicates varying recovery influenced by demographic factors.
Voice changes may occur even when the recurrent laryngeal nerve and the external branch of the superior laryngeal nerve are preserved during thyroidectomy. Although most alterations improve over time, some voice parameters may not fully recover, with outcomes influenced by sex, age, surgical extent, and F0pre. These findings may aid in counseling patients with non-neural PTD.
