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.

Can someone with difficulty breathing, chest tightness, and shortness of breath undergo vocal cord polyp surgery?

Difficulty breathing and chest tightness are very common symptoms in clinical practice. Since there are many triggering factors that can cause these symptoms, it is generally not recommended for patients experiencing difficulty breathing and chest tightness to undergo vocal cord surgery. It is advisable for patients to identify the triggering factors causing these symptoms and effectively improve these symptoms before considering vocal cord surgery. This is important because anesthesia, which is necessary for vocal cord surgery, could be harmful if the patient has underlying cardiovascular diseases. Therefore, it is recommended that such patients find and eliminate the triggering factors, improve their current discomforting symptoms, and only consider vocal cord surgery after their symptoms have fully improved.

Can vocal cord polyps be treated without surgery?

Vocal cord polyps must be surgically treated; otherwise, they will further aggravate. The cause of vocal cord polyps is often due to improper long-term vocal use, shouting loudly, or excessive fatigue. Alternatively, it can be caused by a digestive system disorder, where acid reflux stimulates and leads to vocal cord lesions. Patients will experience persistent hoarseness, and it tends to progressively worsen. Vocal cord polyps generally affect one side. During an examination with an electronic laryngoscope, a smooth, light red or light white abnormal growth can be observed at the anterior-middle third of one vocal cord. The growth is soft and painless, with good vocal cord mobility, but incomplete glottic closure. In terms of treatment, conservative management is ineffective, and the patient requires direct laryngoscopy for polyp removal. The surgery requires hospitalization, and the patient can typically recover and be discharged 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.

Is the recurrence rate of vocal cord polyps high?

Vocal cord polyps are a common and frequently occurring condition in otolaryngology. Usually, if patients strictly protect their voice after undergoing vocal cord polyp surgery, the recurrence rate is generally low. However, patients in professions such as teaching, sales, and singing, who often strain their voices, may experience recurrence of vocal cord polyps. The formation of vocal cord polyps is due to the rupture of capillaries and edema in the vocal cord mucosa, leading to neoplasm proliferation. An electronic laryngoscopy can be used to clearly diagnose the disease. Patients with vocal cord polyps should be advised to strictly rest their voice and avoid excessive vocal strain. Surgical removal of the vocal cord polyps is necessary to cure the condition.

Can vocal cord polyps cause loss of voice?

Vocal cord polyps are benign neoplasms that occur on the vocal cords. They protrude from the surface of the vocal cords. Generally, after the occurrence of vocal cord polyps, surgical treatment is performed to remove them, as vocal cord polyps can cause hoarseness, affecting our work, and impacting our career and life. Severe vocal cord polyps, if not treated, can lead to repeated friction between the vocal cords, which may even result in the potential malignancy. Of course, vocal cord polyps severely affect our voice quality, causing hoarseness and in severe cases lead to voice loss, causing a sensation of air leakage when we speak. In summary, vocal cord polyps can lead to loss of voice.
