In life, we often encounter such scenes, even some people have hoarse voices, some people have loud and small voices, and they can hardly make a sound after speaking. If there is such a person, he may be caused by vocal nodules. Many people don't know much about vocal nodules, and think that the problem is not big, so they don't pay attention to it. This view is wrong. Vocal nodules will cause a lot of harm if they are not treated for a long time. So what? According to the clinical experience of experts in Shenzhen Otolaryngology Hospital for many years, the harm of vocal nodules is mainly manifested in the following aspects: First, vocal nodules may cause hoarseness of patients, resulting in patients' inability to communicate normally, and even affect their voice in serious cases, which will have a great impact on work, study and life. If the vocal nodules are large, there will be obvious hoarseness, which will develop from intermittent to persistent, making it difficult for patients to sing and speak loudly. Second, patients are prone to high-pitched voice cracking, voice fatigue is not lasting, and there will be staccato when doing bass. Things will get worse in the future, and you will be hoarse, because most of the sounds are broken. Vocal cord dysfunction may also be caused by vocal nodules, leading to hoarseness, and because of the increase of vocal cord weight, patients are likely to kick your sputum with blood and neck lymph node metastasis. If vocal nodules are not treated in time, not only will hoarseness gradually worsen, but it may also worsen and persist in the later stage, and vocal nodules may become cancerous unconsciously. The above are some introductions about the harm of vocal nodules.
