There are two treatments for severe snoring: the first is to wear a positive pressure ventilator, and the second is to require surgery. But first of all, we need to distinguish whether the snoring is central or obstructive in nature, if it is caused by central, wearing a positive pressure ventilator is more effective. However, if it is obstructive, surgery is needed. The causes of obstructive snoring are usually nasal cavity diseases, pharyngeal diseases, which generally include chronic rhinitis, hypertrophic rhinitis, deviated nasal septum, nasal polyp, fibrovascular tumor of nasal cavity, malignant tumor of nasal cavity, nasopharyngeal cancer, tonsil hypertrophy, adenoid hypertrophy, soft palate hypertrophy, soft palate prolapse, excessive obesity, jaw deformity, etc. All these diseases can cause patients to snore, so they need to check electronic rhinoscopy as well as electronic laryngoscopy to confirm the diagnosis, then they need to carry out relevant surgical treatment in order to cure.
