Purpose of review Sulcus vocalis is a benign condition of the vocal folds that, according to its severity, can affect the quality of the voice of those who have it. Voice symptoms can range from mild to severe, affecting the quality of life of patients with this condition. Although different surgical and no surgical options have been described, no gold standard treatment has been described. Recent findings New evidence supports congenital, inflammatory, and acquired theories for sulcus vocalis. Also, recent literature demonstrated the role of the epithelium in the pathogenesis, which makes the absence of superficial lamina propria no longer the only accepted hypothesis. Technological developments improved the in-office diagnostics capabilities for this condition, but vocal fold palpation remains the gold standard. Different benign laryngeal conditions are associated with sulcus vocalis and knowing when to treat those is very important. Different treatment options are available for sulcus vocalis, however, results are diverse and no strong recommendations for one over the other can be made. Summary Progress continues to be made in our understanding of sulcus vocalis from diagnosis to treatment. Novel and promising therapeutic strategies have been recently developed for this condition; however, more data and investigations are needed to improve their accuracy and reproducibility.
