What causes hoarseness in children?

Everyone knows that human voice is produced through the vibration and closure of the vocal cords in the throat, so once the throat is infected or inflamed, it will naturally affect a person's voice. This is why people have hoarse voices when they have a cold. Many children often have hoarse voices. Parents are very worried about hurting their children's vocal cords. So what causes hoarse voices in children?

(1) Respiratory tract infection: Acute and chronic laryngitis can cause hoarseness due to congestion, edema, and hypertrophy of the laryngeal mucosa.

(2) Allergic reaction: It can cause allergic edema of the laryngeal mucosa and lead to hoarseness

(3) Laryngeal trauma: such as stabbing, bruising, and damage to the vocal cords caused by excessive or improper use of the voice. Not only can this injure the edges of the vocal cords, but severe trauma can also damage the muscles and nerves in the larynx.

(4) Laryngeal tumors such as laryngeal papilloma and laryngeal cyst can cause incomplete glottal closure and hoarseness.

(5) Recurrent laryngeal nerve paralysis: It can cause paralysis of the laryngeal muscles and result in hoarseness or even inability to make any sound, i.e. aphonia.

(6) Systemic diseases: such as rheumatism and rheumatoid arthritis, if they invade the joints of the larynx, they may cause laryngeal movement disorders and lead to hoarseness. Nephritis, heart disease, hypothyroidism and diabetes can all cause vocal cord edema and lead to hoarseness. Myasthenia gravis causes weakness of the laryngeal muscles, which is also one of the causes of hoarseness. Endocrine changes such as the menstrual period of a teenage girl and the voice change period of a teenager can also cause mild congestion and edema of the vocal cords and hoarseness.

What causes hoarseness in children? After reading the above introduction, you should have a clear understanding. Whether it is respiratory infection or laryngeal trauma and other diseases that cause the voice to become hoarse, everyone should not worry too much. As long as the throat recovers, the voice will naturally return to normal, so don't force your child to change his normal pronunciation method.
