When some patients’ vocal folds are more seriously damaged, they are still hoarse one month after surgery, which may be a normal performance; when the vocal folds are mildly diseased, they are still hoarse one month after surgery, which may be an abnormal reaction. 1. When the vocal folds are damaged more seriously, such as bilateral vocal polyps with wider bases and larger volumes, complete vocal abstinence is required after surgery, and some patients also need to follow the doctor’s instructions to standardize the use of medication, while allowing the vocal folds to be in a state of rest. One month later, there is still hoarseness, unable to return to normal, usually to review the laryngoscopy to clarify the cause, or reflux pharyngitis or scarring hyperplasia. 2. Some patients with unilateral vocal polyps or bilateral vocal polyps, the volume are small, the trauma in the operation is not serious, postoperative standardized nebulization, voice and other symptomatic treatment, a month’s time, such as those who have not fully recovered, should be timely review laryngoscopy, to check whether there is a residual body or postoperative adhesions, etc., these symptoms are not normal. Those who still have hoarseness one month after vocal cord surgery are recommended to actively seek medical attention, standardize medication and treatment after clarifying the cause.
