Symptoms of vocal cord paralysis in children

summary

Pediatric vocal cord paralysis, or laryngeal paralysis, is a clinical manifestation rather than an independent disease. When the laryngeal motor nerve (recurrent laryngeal nerve) is damaged, there are three types of paralysis: vocal cord abduction, adduction or muscle relaxation. Clinically, because the left recurrent laryngeal nerve has a long course, the left vocal cord paralysis is more common. Let's talk about the symptoms of infantile vocal cord paralysis.

Symptoms of vocal cord paralysis in children

（1） Unilateral incomplete paralysis: mainly vocal cord abduction disorder, mostly not significant. Under indirect laryngoscope, one side of the vocal cord was close to the midline, which could not be abducted when inhaled, but could be closed when pronouncing.

(2) unilateral complete paralysis: the function of vocal cord abduction and adduction disappeared. The examination showed that the vocal cord was fixed in the paramedian position, arytenoid cartilage was tilted forward, the affected vocal cord was lower than the healthy side, the vocal cord could not be closed when pronouncing, and the voice was hoarse and weak.

(3) bilateral incomplete paralysis: rare, mostly due to thyroid surgery or laryngeal trauma. The vocal cords on both sides can not be abducted but close to each other's midline. The glottis is like a small fissure. The patient may have no symptoms when he is calm, but he often feels difficult in physical activity. In case of upper airway infection, severe aspiration difficulty may occur.

matters needing attention

1. Drink 1000 to 2000 ml boiled water a day to keep your throat moist to replenish the water lost by long-term use of vocal cords. 2. Speak with appropriate volume and use microphone flexibly. To have a stable mood, adequate sleep, appropriate exercise, in order to maintain good vocal cord elasticity. 3. Don't smoke or drink, and avoid other things such as coffee, strong tea, chili, cold drinks, chocolate or dairy products. Pay attention to the tone of speech, not too low or too high, so as to reduce the resistance and vocal cord tension. Some people think that speaking in low voice can make vocal cords rest. In fact, speaking in low voice is a sound made under the condition of tense vocal cords, and vocal cords will be more tired after a little longer.
