Vocal cord polyps are benign neoplasms that occur on the vocal cords. Often, they are treated through surgical removal. After the removal of vocal cord polyps, there is a certain rate of recurrence.

This is because the inflammation in the vocal cord area has not been fully controlled after the surgery. Recurrent and frequent upper respiratory infections stimulate the vocal cords. Also, inappropriate use of the voice, such as frequent vocalization and loud screaming, can damage the vocal cords and lead to the recurrence of vocal cord polyps.

Other factors, such as diet, spicy and irritating foods, alcohol, and chili stimulation, can cause congestion and edema of the vocal cords to persist, leading to the recurrence of vocal cord polyps. Therefore, it’s important to be mindful of these aspects after surgery for vocal cord polyps.

Can vocal cord polyps disappear on their own?

Vocal cord polyps cannot disappear on their own because they are a benign tumor. Without local surgical treatment, vocal cord polyps will continue to grow, causing the patient's hoarseness to worsen further. In severe cases, it can cause the patient to have breathing difficulties, leading to choking and even death. Vocal cord polyps are caused by improper use of the voice over a long period, such as yelling loudly or excessive tiredness, leading to pathological changes in the vocal cord mucosa. They can cause persistent hoarseness in patients. During an examination with an electronic laryngoscope, a smooth, light red or pale white abnormal neoplasm can be found on the anterior-middle third of one vocal cord. The vocal cord moves well, but does not close completely. In terms of treatment, patients need to undergo local surgical excision to heal. After surgery, it is important to protect the vocal cords by avoiding yelling loudly or speaking entirely, and complete recovery can generally be achieved within about a week.

Do vocal cord polyps require a biopsy?

Vocal cord polyps are benign neoplasms located on the vocal cords, typically protruding from the surface or the free edge of the vocal cords. Therefore, the removal surgery for vocal cord polyps is generally performed under laryngoscopic and microscopic visualization. The procedure usually involves direct excision followed by pathological examination, and a biopsy is generally not conducted before the surgery. Thus, vocal cord polyps are typically treated through direct surgical removal without a pre-surgery biopsy. It is also important to avoid excessive misuse of the voice after the surgery to prevent recurrence of the vocal cord polyps.

The difference between vocal cord polyps and vocal cord nodules

Vocal cord polyps and vocal cord nodules are diseases caused by incorrect pronunciation or overuse of the voice, with the main clinical manifestation being hoarseness. The difference between vocal cord polyps and vocal cord nodules lies in their appearance under a laryngoscope: Vocal cord polyps often occur on one vocal cord, typically in the anterior one-third where a translucent, smooth swelling is found. This swelling can either have a broad stalk or a smaller stalk, and often, a hole can be observed with respiration. Vocal cord nodules are smaller and usually located symmetrically on the anterior one-third of both vocal cords. This implies that while polyps are commonly found on one vocal cord, nodules occur symmetrically on the anterior one-third of both vocal cords. From a general perspective, vocal cord polyps are wider and larger, whereas vocal cord nodules are only nodular lesions.

The causes of recurrent vocal cord polyps

The recurrence of vocal cord polyps is primarily due to patients not taking care to protect their voice usage, improper voice use, and failing to quit bad habits such as smoking and drinking. The main cause of vocal cord polyps is edema in the Reinke's layer of the vocal cord mucosa, which leads to the proliferation of the surface mucosa. The main symptom in patients is a hoarse voice. After undergoing support laryngoscopy and surgical removal of the vocal cord polyps, patients are required to refrain from speaking for three to four weeks to allow the vocal cord mucosa to recover and heal. If patients do not take care of their voice during this period, there is a possibility of recurrence of the vocal cord polyps.

Can vocal cord polyps turn cancerous?

Vocal cord polyps themselves are a type of benign lesion, with a very, very small chance of becoming malignant. However, if vocal cord polyps recur frequently, especially in conjunction with unhealthy lifestyle habits such as long-term smoking and drinking, there indeed exists a possibility of malignant transformation. Overall, though, this probability is relatively low, and the vast majority of cases are benign. However, in cases of frequent recurrence, it is important to watch for moderate or severe atypical hyperplasia, as this condition could potentially progress to cancer. Regular laryngoscopic examinations are needed in such cases, typically every three to six months. Additionally, it is important to avoid smoking and drinking, and to avoid excessive use of the voice.
