Loud snoring needs to be checked for the cause of snoring in the hospital and surgical treatment can be performed to cure it. Snoring, also called snoring, is clinically called sleep apnea syndrome. It can be generally divided into two types: the first is the central type; the second is the obstructive type. The first type, the central type, is very rare and is caused by head trauma or head tumor compression and requires positive pressure ventilator for treatment. The second type is the obstructive type, such as obesity, nasal deformities and throat diseases or deformities of the lower jaw, which may cause blockage and lead to snoring and thus poor breathing, and require hospital examination with electronic rhinoscopy and laryngoscopy. Nasal diseases including chronic rhinitis, deviated septum, nasal polyps, adenoid hypertrophy and tonsillar hypertrophy, or high tongue root, soft palate hypertrophy and oral mucosa narrowing may cause obstructive snoring, which can only be completely cured by finding the cause.
