Vocal cord bleeding is relatively rare and generally occurs in two situations. The first is when the patient has undergone surgery on the vocal cords, such as surgery on vocal cord polyps or vocal cord nodules, where the bleeding is quite small and can be stopped in about 1-2 minutes to recover. In the second case, the patient has been hit by a serious external force and the cartilage of the patient’s larynx has collapsed or fractured, which may damage the patient’s vocal cords. In such cases, the patient’s bleeding is significant and often requires surgery to resolve. This is because avoiding severe bleeding from the patient’s vocal cords or other surrounding mucous membranes can lead to inadvertent choking and even life-threatening coughing. If treated aggressively, the patient’s condition can only improve and stabilize in about 2-3 days. Therefore, it is recommended that patients must pay attention to protecting their larynx from damage in their lives.
