summary

When cold, sometimes inflammation spread to the throat, laryngitis. The main characteristics are throat congestion, vocal cord congestion, edema, resulting in laryngeal stenosis, resulting in hoarseness. So what is the cause of cold hoarseness?

How is child cold voice hoarse to return a responsibility

First: vocal cord mucosal lesions: the vocal cord mucosa has a certain viscoelasticity, with the help of laryngeal joint and muscle movement, so that the two sides of the glottis free edge of each other, due to Bernoulli's phenomenon, the vocal cord vibration. Due to the different vibration frequency and intensity, the performance of different tones and sound. When the lesions on one or both sides of the vocal cord edge, whether inflammation or new organisms, affect the vibration of the mucosal edge, there is a difference in the vibration frequency between the two sides, resulting in a murmur, which is characterized by hoarseness.

Second: vocal cord quality change: both sides of the vocal cord quality should be consistent, when the weight of abnormal, such as vocal cord submucosal edema, bleeding, vocal cord unilateral atrophy, can make vocal cord weight change, affect vocal cord elasticity, vibration disorder is not synchronous, noise, hoarseness.

Third: vocal cord paralysis: vocal cord movement is dominated by the external branch of superior laryngeal nerve and recurrent laryngeal nerve, especially the latter. Recurrent laryngeal neuropathy can affect glottic movement regardless of the cause. The main reason is that the muscle tension of paralyzed vocal cord is weakened, which affects the vibration frequency. The vocal cord vibration is obviously affected, resulting in hoarseness.

matters needing attention

Our daily use of pangdahai is not the fresh fruit of pangdahai, but the dry fruit. If it's just for prevention, generally use one or two boiling water to make tea. If it is used to treat hoarseness, the dosage can be slightly increased, and appropriate with honey.
