The most common cause of vocal cord damage is edema and congestion of the vocal cord mucosa caused by viruses or bacteria. Anti-inflammatory and anti-viral drugs are mainly used, such as Blue Scutellaria Oral Liquid or Paediatric Shuangjin Qinghe Oral Liquid, together with Golden Voice and Open Voice Pill or Golden Voice and Throat Pill. If the vocal cord is damaged due to viral or bacterial vocal cord nerve paralysis and vocal cord fixation, anti-viral drugs and nerve nourishing drugs can be applied. If there is some trauma to the vocal cords, depending on the severity of the vocal cords, anti-inflammatory drugs are also generally used. However, if the vocal cords have benign or malignant tumors, drug treatment is not effective, and surgery is generally considered.
