The symptoms of snoring like thunder are mainly caused by the patient’s severe pharyngeal stenosis and high tongue root. When a patient has a narrow pharyngeal gate and a high tongue root, the entrance to the pharynx is very narrow. When the patient is lying down or lying on the side, the tongue root drops back, and the enlarged tonsils, tongue and palate arch and pharyngeal and palate arch close to the midline, causing the entrance to the pharynx to be extremely narrow, and the airflow is restricted when breathing, and the patient then has inspiratory respiratory difficulty, at which time the airflow will excessively rub the pharyngeal mucosa and tongue root mucosa and produce loud snoring. If the patient is diagnosed with severe stenosis of the pharyngeal portal, he should undergo pharyngeal portal enlargement and tongue root plasma ablation under general anesthesia in time, and the snoring sound can be reduced after the pharyngeal portal is opened.
