Patients with vocal cord nodules usually do not undergo cancerous changes. The main causes of vocal cord nodules are related to improper use of the voice, excessive vocalization, and other factors. The pathological basis for the formation of vocal cord nodules involves edema in the Reinke's layer of the vocal cord mucosa, causing symmetrical hyperplasia of the vocal cords on both sides. The main symptoms in patients are hoarseness and difficulty in producing high-pitched sounds. The primary treatments for patients with vocal cord nodules currently include medication and surgery. Additionally, it is important for patients to protect their voice in daily life, practice voice rest, and reduce unhealthy habits like smoking and alcohol consumption to help prevent the occurrence of vocal cord nodules. (Medication should be used under the guidance of a doctor.)
