Vocal cord nodules are small, benign growths that develop on the vocal cords due to overuse or strain. They are often referred to as "teacher's nodules" because individuals who frequently use their voice, such as teachers or singers, are more prone to them. These nodules can cause hoarseness, a raspy voice, and difficulty speaking. Treatment typically involves voice therapy to reduce strain and improve vocal technique. In some cases, surgery may be necessary to remove the nodules if conservative measures do not provide relief. Early intervention can help prevent further vocal damage and promote healing.
