One, the cause of snoring: the airway received an obstruction, such as enlarged tonsils, hyperplastic adenoids, incorrect body position, causing local narrowing of the airway, causing vibration of the airway airflow, causing snoring. Second, exclude improper posture caused by: occasional occurrence, after changing the sleeping posture is gone, due to improper posture, caused by airflow restriction, no need to be anxious. Third, snoring occurs every day: you need to go to the hospital for further examination and treatment. 1, adenoid hypertrophy: If a child with adenoid hypertrophy must be examined to be able to detect it, rhinoscopy or lateral nasopharyngeal or CT examination of the nasopharynx can be performed. If the pressure on the airway is more than 2/3, it should be treated surgically, otherwise it will affect the normal growth and development of the child. 2, tonsillar hypertrophy: If the tonsils are hypertrophied by more than 2 degrees, the symptoms of snoring will appear. If more than 3 degrees with obvious sleep breathing disorder, surgical treatment can be performed. 3. Deviated septum: Sometimes the septum (the bone that separates the two nostrils) will be pushed to one side, obstructing the airflow to the nostrils, and as a compensation, the child will inhale more air with the nostril that is not blocked on that side, and so make noise. Surgical correction is the only way to treat deviated septum. 4. Softening of laryngeal cartilage: In the first few months of life, the cartilage around the trachea sometimes softens, causing the child’s trachea to partially fold when he or she breathes. If this happens, the doctor will see the normal indentation just above the sternum sink in slightly when the baby inhales. As the baby grows, it will slowly disappear. 5, rhinitis, sinusitis: symptomatic drug treatment.
