Sulcus vocalis is a groove or indentation in the vocal fold that affects its ability to vibrate properly. It can be congenital or develop over time from chronic inflammation or prior vocal fold trauma. Because the groove is often subtle, it may go undiagnosed until the voice becomes significantly affected. Patients report a weak, breathy, or strained voice, often with limited vocal endurance. Voice quality may not improve with therapy alone. Treatment depends on severity. In mild cases, voice therapy may help improve compensation. For more significant sulci, we offer microlaryngoscopy with injection of PRP, fat, or hyaluronic acid to improve vocal cord vibration. Recovery is gradual, and therapy plays an important role before and post-procedure.
