Recurrent vocal cord polyps can potentially lead to cancerous changes. Vocal cord polyps are caused by improper use of the voice over an extended period, such as yelling loudly or excessive fatigue, leading to changes in the vocal cords. Generally, it affects one vocal cord and causes the patient to experience persistent, progressive hoarseness. During an examination with an electronic laryngoscope, a neoplasm can be observed on the anterior-middle third of the affected vocal cord. This neoplasm is smooth, pale white or pale red, and has a thin stalk, leading to incomplete closure of the vocal folds and subsequent hoarseness. In terms of treatment, conservative methods are ineffective. The patient requires a microlaryngoscopy under general anesthesia to remove the vocal cord polyp. Postoperative care includes antibiotics to prevent local infections, and the patient can typically recover and be discharged about a week after the surgery.

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.

The difference between vocal cord polyps and pharyngitis

Pharyngitis is primarily a nonspecific inflammation of the throat, which can be divided into acute pharyngitis and chronic pharyngitis. Acute pharyngitis is mainly caused by bacterial infections affecting the mucous membrane and submucosal tissues of the throat, leading to symptoms such as dry throat, burning sensation, sore throat, and pain when swallowing. The main pathogens involved are often streptococcus and staphylococcus, among others. Patients with chronic pharyngitis mainly experience a foreign body sensation in the throat, along with dryness and itchiness. In contrast, patients with vocal cord polyps, which mainly differ from pharyngitis, exhibit hoarseness. Typically, pharyngitis patients do not exhibit obvious hoarseness. Differentiation between the two can be achieved through an examination with a laryngoscope, which can determine the presence of obvious polyp growth on the vocal cords, thereby distinguishing between vocal cord polyps and pharyngitis.

Can vocal cord polyps be treated without surgery?

Vocal cord polyps are an occupying lesion in the throat area, taking the form of relatively larger polypoid formations. Vocal cord polyps typically require surgical removal, mainly performed under a microscope-supported laryngoscope. In the early stages of vocal cord polyps or when the polyps are small, some doctors may use medications, such as corticosteroid hormones or certain traditional Chinese medicines that clear the voice and benefit the throat. However, as vocal cord polyps tend to grow larger, reaching the extent of polyp development, it is difficult to treat them with medications alone and eliminate them pharmacologically. Thus, the prevailing recommendation for vocal cord polyps is surgical removal.

Early symptoms of recurrent vocal cord polyps

Vocal cord polyps are a relatively common otolaryngological disease. If vocal cord polyps recur, they can cause related clinical symptoms, the most common being a hoarse voice. Some patients experience persistent hoarseness, while others have sporadic hoarseness. Moreover, the hoarseness generally becomes more pronounced after excessive use of the voice. In terms of treatment, the first step is to visit an otolaryngologist. It is recommended to undergo a laryngoscopy to examine the size of the polyp in detail. If the polyp is relatively small, conservative treatment may be considered, commonly involving oral medication combined with nebulization therapy. However, if the polyp is particularly large, surgery might be necessary.

The difference between vocal cord polyps and laryngeal cancer

The difference between vocal cord polyps and laryngeal cancer is firstly notable in their nature. Vocal cord polyps are benign lesions, and their removal generally does not significantly affect the patient's quality of life or lifespan. Laryngeal cancer, as the name implies, is a malignant lesion that greatly affects both the patient's quality of life and lifespan. Location-wise, vocal cord polyps are found on the vocal cords, while laryngeal cancer can be located in one of three areas: on the vocal cords, known as glottic laryngeal cancer; below the vocal cords, known as subglottic laryngeal cancer; and above the vocal cords, known as supraglottic laryngeal cancer. The prognosis for vocal cord polyps is very good; after surgery, if the patient rests well, their future quality of life is generally unaffected. Laryngeal cancer is divided into three types: glottic, supraglottic, and subglottic, with glottic being the most common, accounting for about 80%. This type of laryngeal cancer usually presents early symptoms such as hoarseness, similar to vocal cord polyps. Therefore, glottic laryngeal cancer can often be detected early. With prompt and correct treatment, the postoperative results can be good. As it typically involves highly differentiated squamous cell carcinoma, if it is completely excised surgically and regularly reviewed postoperatively, it doesn't greatly impact lifespan or quality of life. In contrast, subglottic and supraglottic laryngeal cancers often show symptoms later, which means they tend to be diagnosed at a later stage, usually at a mid to advanced stage. Supraglottic laryngeal cancer, in particular, is prone to cervical lymph node metastasis, thus usually having a poorer prognosis compared to glottic laryngeal cancer. There's also a higher likelihood of recurrence and metastasis, and the surgery may involve greater trauma. These are the main differences.
