throat polyp
Introduction
Brief introduction of throat polyps Polyps are the most common pseudotumor of the throat. Men have more morbidity than women, and are more common in young adults. Polyps occur in the first 1/3 and the middle third of the free edge of the vocal cords. Other parts of the larynx (such as false vocal cords, larynx, sacral cartilage, small horny nodules, and subglottic) can also occur, but the incidence is low. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: blocked throat
Cause
Cause of laryngeal polyps
It is generally believed that vocal cord polyps are caused by edema of Renke's layer. The occurrence of edema is mostly due to improper vocalization, excessive vocalization, and the vocal cords are often damaged by mutual friction. Sudden submucosal bleeding is caused by sudden exertion. Smoking, industrial dust or chemical gas chronic stimulation, inflammation and allergic reactions make Renke's layer Venous plexus congestion, edema, hemorrhage and thrombosis occur, which begins with a polypoid change followed by fibrous tissue hyperplasia. There are also studies on vocal cord local circulatory disorders, decreased superoxide dismutase (SOD) activity in vocal cord mucosa, compensatory changes due to glottic insufficiency, local anatomical abnormalities, and autonomic dysfunction.
Prevention
Laryngeal polyp prevention
There is no effective preventive measure for this disease. Early diagnosis and early treatment are the key to the prevention and treatment of this disease.
Complication
Laryngeal polyp complications Complications
Those with large polyps may have serious consequences such as difficulty breathing and loss of sound.
Symptom
Symptoms of laryngeal polyps Common symptoms The frequency of hoarse speech is small, no... pharyngeal foreign body sensation sound abnormal breathing difficulty asthma
The main symptom is hoarseness, which varies with the size, shape and location of the vocal cord polyp, the change in sound quality, and the degree of hoarseness. The light is intermittent hoarseness, the sound is easy to fatigue, the tone is rough, the treble is difficult, and the heavy one is hoarse or even lost. Huge polyps are located between the vocal cords on either side, which can completely ruin and can even cause difficulty breathing and wheezing. Polyps falling in the lower glottis can cause cough due to irritation.
Examine
Laryngeal polyp examination
Laryngoscopy revealed a new organism with a smooth, translucent pedicle or pedicle in the middle of the vocal cords. Polyps are mostly grayish or light red, occasionally purple, often the size of mung bean and soy. Vocal cord polyps are usually more common on one side, or both sides. The pedicled vocal cord polyps can move up and down with the respiratory airflow, sometimes hidden in the subglottic cavity, which is easy to ignore when checking. Under the dynamic laryngoscope, the vocal cords are periodically deviated, and the symmetry, amplitude, and mucosal waves are weakened or disappeared, and the vibration-off phase is weakened.
Diagnosis
Diagnosis and differentiation of laryngeal polyps
According to the symptoms, local examination is generally not difficult to diagnose. If the vocal cords are unclear, they can be added for fiber vocal or electronic laryngoscopy. The diagnosis of vocal cord polyps is distinguished from vocal cord cysts, vocal cords, vocal cord adhesion, and vocal cord cancer. The diagnosis still relies on pathological examination.
