vocal cord injury in children
Introduction
Introduction Children's vocal cords are weak and vulnerable to injury. In the early days, the treble was broken, the sound was easy to fatigue and not long-lasting, and the bass was unchanged. In the future, it gradually worsened. Because most of the sounds ruptured and the hoarseness progressed from intermittent to continuous, the patient could not sing and could not speak loudly.
Cause
Cause
Some children are lively and active, eager to win, to attract the attention of others, to answer questions in the classroom or to greet children in the game, there is a habit of screaming and screaming; some children always think that the sound is louder when singing or singing songs. Good, and some children develop a petite personality. When they are not satisfied, they often use loud crying and screaming methods, which will bring the consequences of damage to the vocal cords.
In addition to shouting, children with chronic tonsillitis, proliferative hypertrophy and chronic paranasal sinusitis, because the secretions adhere to the throat wall, so that children often involuntarily frequently "giggle" clear sound, over time will damage vocal cord. Some children with hearing disabilities develop a habit of talking loudly and can also damage the vocal cords. Severe childhood vocal cord injury may affect the development of the vocal cords until the child's youthful voice changes.

It is difficult to pronounce and speak, hoarse or only make a short, hoarse voice. Diagnosing patients often involves intermittent or persistent hoarseness in inappropriate or over-sounding. Both sides of the vocal cords have the same symmetry lesions, such as corn, grayish white, smooth surface, slightly basal part of the blood. A small number of small blood vessels can be seen on the base, and the knots on both sides of the sound are attached to each other to prevent the vocal cords from closing.
Diagnosis
Differential diagnosis
Differential diagnosis of vocal cord injury in children:
1. Vocal cord paralysis: Paralysis of vocal cord or throat paralysis is a clinical manifestation, not an independent disease. When the motor nerve (recurrent laryngeal nerve) of the larynx is damaged, there are three types of paralysis: vocal cord abduction, adduction, or muscle tension relaxation. Clinically, due to the longer stroke of the left recurrent laryngeal nerve, the left vocal cord paralysis is more common.
2, glottic dyskinesia: glottic dyskinesia is caused by a variety of causes of glottal motor dysfunction, clinical vocal disorders as the main manifestation of a type of disease. Can be divided into neurological, muscular, joint and functional.
3, hoarse voice: hoarse voice, or hoarseness, refers to the loss of a round and clear sound quality when the sound. Clinically, there are varying degrees of changes in sound quality. The lightest is called "hair", that is, there is a certain degree of sound quality change when the treble is high, and the sound becomes rough. "Sand" means that the sound quality of almost all tones has changed. Moderate changes in sound quality are called . At this time, in addition to the rough and impure quality, there is still a leak, indicating that the bilateral vocal cords have significant gaps in pronunciation. Severe sound quality changes are called "dumb", that is, the glottal gap is large when the sound is emitted, the vocal cords cannot vibrate, and only the whisper can be heard.
It is difficult to pronounce and speak, hoarse or only make a short, hoarse voice.
