Vocal cord polyps

Introduction to vocal cord polyps Vocal cord polyps refer to the grayish-white, smooth-surfaced polypoid tissue that occurs on the anterior central edge of one side of the vocal cords. It is mostly single or multiple on one side, pedicled or broad-based, often grayish-white translucent, or small red protrusions. Those with pedicles often move up and down with the breath, and the larger ones can block the glottis from breathing difficulties and affect pronunciation. The position is mostly located in the middle third of the vocal cord junction. In general, the vocal cord nodules in children can be temporarily not treated. Adults with small nodules or polyps are usually treated by surgery. After the operation, the patient should be routinely banned and can be treated with atomization. At the same time, pay attention to the pronunciation method and avoid excessive vocalization to prevent recurrence. basic knowledge The proportion of illness: 0.013% Susceptible people: no special people Mode of infection: non-infectious Complications: chronic laryngitis

Vocal polyps

Improper vocalization or excessive vocalization (30%):

The vocal cord polyps are mostly caused by improper vocalization or excessive vocalization. They can also be caused by a strong vocalization. Therefore, this disease is more common in patients who use occupational sounds or excessive use of sound, especially for long-term use of excessive sound, or improper use of sound. An extremely important motivating factor, the disease is common in occupational voicers and over-sounding people such as yelling, adult children can be sick.

Other causes (20%):

Can also be secondary to upper respiratory tract infections, various causes of chronic laryngitis, can cause vocal cord polyps. Chronic laryngitis is a chronic inflammation caused by a non-specific pathogen infection of the larynx mucosa. It is one of the most common laryngeal diseases, mainly characterized by bilateral vocal mucosal inflammatory lesions. It is characterized by hoarseness and increased secretion of the throat. Can be divided into chronic simple laryngitis, chronic proliferative laryngitis, chronic atrophic laryngitis, chronic hypertrophic laryngitis.

pathology:

At the beginning, at the edge of the vocal cord membrane, in the potential gap under the epithelium, there is accumulation of tissue fluid, local edema, vasodilation and hemorrhage, and then gradually pale edema-like translucent glassy degeneration or fibrosis, forming an ellipse or Round vocal cord polyps, sub-limited and broad-based 2 types.

Vocal cord polyp prevention

1, timely treatment of acute laryngitis, to prevent the evolution of chronic.

2, to prevent excessive use of sputum, for teachers, literary and art workers should pay attention to the correct method of vocalization, especially during the cold.

3. Strengthen labor protection, and properly handle harmful gases and dust in the production process.

4, the appropriate time to ban the sound, avoid excessive use of sputum, quit smoking and drinking hobbies, and actively treat adjacent organ lesions.

Vocal cord polyp complications Complications, chronic laryngitis

The occurrence of vocal cord polyps is mostly due to long-term vocalization, or after a strong vocalization. Can also be secondary to upper respiratory tract infections, colds, acute and chronic laryngitis, rhinitis can be the cause of the disease, smoking can stimulate the vocal cords, some menopausal women with this disease is related to decreased hormone levels, lighter only slight sound changes The heavy hoarseness is obvious and even the sound is difficult.

Symptoms of vocal cord polyps Common symptoms Throat sounds abnormal voice sound coarse dysfunction throat increased dyspnea vocal cords aging glottis short and narrow vocal band hypertrophic vocal cord atrophy

The main symptom is hoarseness, the extent of which varies depending on the size and type of polyp. The small localized polyps have only a slight change in sound. The broad polyp of the polyp is heavier, the tone is low and monotonous, can't sing, or even lose the sound, big polyp Can cause throat and difficulty breathing.

Vocal cord polyp examination

First, laryngoscopy: vocal cord polyps on one side of the gray-white or reddish-smooth scorpion, pedicle or broad-based or diffuse vocal cords on the edge of a gray sausage-like mass.

Second, optical examination: combined with laryngoscope and surgical microscope for laryngeal lesions or surgery, is a common examination of vocal cord polyps.

Third, dynamic laryngoscopy: used to identify organic and functional lesions; determine the extent and extent of organic lesions; determine the type or severity of vocal numbness, and with the ankle joint fixation, vocal cord polyps, trauma, etc.; Initially determine the nature of the vocal cord mass; perform various tests on the sound worker and guide the pronunciation practice.

Fourth, other inspections:

1 lateral X-ray can observe the epiglottis anterior space, the epiglottic throat and the soft tissue of the lower jaw, and can measure the vocal cords and observe the vocal cord numbness.

2 laryngeal tomographic fault for clinical observation of vocal cord vocalization and presence or absence of occupational changes, mainly to observe the vestibular vestibule, ventricular septum, larynx, vocal cord and subglottic area orbital changes, while also viewing glottic closure and The two-way change of the glottis is open.

3 laryngeal CT examination, used to understand the tissue and anatomy of the throat and nearby.

Vocal cord polyp diagnosis

diagnosis

1. Different levels of hoarseness.

2, laryngoscopy: vocal cord polyps on one side of the gray-white or reddish-smooth scorpion, pedicle or broad-based or diffuse vocal cord edge grayish sausage-like mass.

Differential diagnosis

Vocal cord polyps are a type of chronic laryngitis and should be differentiated from vocal cord nodules.
