Sulcus Vocalis.

Sulcus vocalis, defined as a type of groove along the free edge of the vocal fold, disrupts the normal, pliable vocal fold cover, causing alterations in the intrinsic mucosal wave. The primary symptom is breathy, effortful dysphonia. Diagnosis may be challenging, and this classically has led to difficulties with identification and management. Treatment options, although often promising, have been notoriously unreliable. Current understanding, considerations for management, and future treatment options are explored.
