Patients with vocal cord nodules are advised not to smoke, as cigarettes have a relatively strong irritant effect and directly stimulate the vocal cords. This may exacerbate the condition of vocal cord nodules and may also cause further hoarseness. Moreover, smokers are at a higher risk of developing cancerous changes in the vocal cords. Therefore, patients should not smoke or drink alcohol and should regularly visit an otolaryngologist for a laryngoscopy to monitor the changes in the vocal cord nodules. Most patients can achieve good control and relief of their condition through timely medication treatment and nebulization, with only a small number needing to consider surgical treatment.
