Usually, the first thing to pay attention to is the vocal method, and don't let the vocal cords appear nodules.
Second, protect your voice. Girls should not use their voices during their physiological period. Be careful not to drink cold water or eat ice.
In recent years, the incidence of vocal cord diseases among professional vocal workers such as teachers and actors has gradually increased. The most common diseases are vocal cord inflammation, vocal cord polyps, vocal cord nodules, and even intractable vocal cord leukoplakia, laryngeal keratosis and vocal cord cancer. Many teachers think that hoarse voice is not a big problem, there is no need to make a mountain out of a molehill, just take some anti-inflammatory drugs. In fact, the first hiss is the beginning of the lesion, at least it has buried unpredictable hidden dangers. So remind the teacher to pay attention to protecting his voice.
People should use voice, and voice is the throat. It is an important vocal organ and the portal of lower respiratory tract, which is composed of cartilage, vocal cords and ventricular bands. Vocal cords are like two leucorrhea, similar to strings. When pronouncing, the air exhaled by the lungs impacts the vocal cords, and then passes through the vocal cords of the throat cavity, pharynx cavity, nasal cavity and chest cavity, plus the coordinated movement of lips and teeth, making a sound. In the process of vocalization, the tension, length and thickness of vocal cords play a decisive role in vocalization.
The sound is produced by the gas exhaled from the lungs impacting the closed vocal cords, forming language through the lips, teeth and tongue, and then forming a pleasant sound through the singing cavity. The front end of vocal cord is fixed at the intersection of thyroid cartilage, and the back end is fixed on the left and right cleft cartilage respectively. These two chapped cartilages rotate inward and outward with the vocal cords. When they turn inward, the vocal cords close and sound, and when they turn outward, the vocal cords open and breathe.
The vocal cords are like two leek leaves, with thin, neat and straight edges and free movement. If any one of them has problems, it will lead to hoarseness.
The voice of vocal cord hypertrophy will become hoarse, such as vocal cord swelling in acute laryngitis and vocal cord hypertrophy in chronic laryngitis.
Protrusion of vocal cord edge, such as vocal cord polyp, vocal cord nodule, papilloma, laryngeal cancer, etc. , making the vocal cords closed and relaxed, so the voice is hoarse.
Poor vocal cord tension, such as vocal cord relaxation, can not be tightened, when closed, a shuttle gap is formed between vocal cords, which is not closed tightly, resulting in hoarseness.
Limited vocal cord movement, such as vocal cord paralysis, laryngeal stenosis, etc. The damaged vocal cords can't get close to the middle. When you speak, you will feel tired and hoarse because you are exhausted.
The tension of vocal cords is too high, like male and female voices. The reason is that the vocal cords are too tight after voice change, so men speak like women.
The tension of vocal cords is poor, as thick as a female voice. This is because the vocal cords are looser after the voice change, so women speak like men.
Check in time after hoarseness. In addition to routine examination, early minor lesions can be found by examining the larynx with fibrolaryngoscope. Treatment methods mainly include the following:
Conservative treatment such as hoarseness caused by acute laryngitis can eliminate edema by using antibiotics. Chronic laryngitis can be treated by physical therapy, aerosol inhalation and other methods.
Tumor resection caused by hoarseness can be performed under laryngoscope, and the effect is very good. After the operation, you can keep your voice function and talk as usual.
Vocal cord correction male and female voices, female male voices or vocal cord paralysis can be corrected by surgery, and satisfactory results can be achieved.
Besides, it is very important to learn scientific pronunciation. We should be good at using high, low and tenor alternately, because we use 1/3 in front of the vocal cords for high notes, 1/3 in the vocal cords for middle notes and 1/3 behind the vocal cords for low notes. This pronunciation is not only vivid, but also allows the vocal cords to rest alternately. Also be careful not to use the voice too long, too high and too tired. Quit smoking, drink less, treat acute inflammation, acute laryngitis and respiratory diseases in time, and reduce vocalization when voice changes, colds and menstrual periods.
