The actual fact is that you will be able to get a lot more than just a few of these. The reason for this is as follows The laryngeal tinnitus in infants and children is caused by the collapse of the laryngeal cavity due to the soft and flaccid laryngeal tissues during inhalation, which is called congenital laryngeal tinnitus, also known as laryngeal cartilage softening. It often occurs shortly after birth, and as the laryngeal cartilage develops with age, the laryngeal tinnitus gradually disappears. The cause of laryngeal tinnitus is due to malnutrition during pregnancy and fetal calcium deficiency, resulting in weak laryngeal cartilage, increased negative pressure during inspiration, causing the edges of both sides of the epiglottis cartilage to curl inward and touch, or the epiglottis cartilage is too large and soft, and the two sides of the arytenoid folds are close to each other, narrowing the laryngeal cavity into a flap-like tremor. Inspiratory arytenoid cartilage prolapse is another cause. The laryngeal tinnitus of this child is not caused by the weakness of the laryngeal cartilage, but by the downward rotation of the arytenoid cartilage during inspiration, which causes the loose tissue on it to protrude toward the front of the vocal folds and block the vocal folds. The symptoms of laryngeal tinnitus are as follows: laryngeal tinnitus gradually occurs 1~2 months after birth. It is mostly persistent or intermittently aggravated. Laryngeal tinnitus occurs only during the inspiratory period and may be accompanied by inspiratory dyspnea. There are also cases where the laryngeal tinnitus is not usually obvious but occurs immediately after a slight stimulus. Some of them are position-related, aggravated when lying on their backs, but less so when lying prone or on their sides. Most children are in good general condition and do not have hoarse cries. If the symptoms are not severe, congenital laryngeal tinnitus usually resolves spontaneously by the age of 2 to 3 years. If it occurs, tracheotomy is required. Acute laryngitis can cause respiratory distress and requires special attention.
