There are many causes of snoring, such as insufficient muscle tone in the oropharynx, anatomical abnormalities, pharyngeal space-occupying lesions, and restricted nasal ventilation, etc. Medication, general treatment, and surgical treatment are used depending on the cause of the problem. The most effective treatment for all cases of snoring does not exist. 1. Allergic rhinitis: patients with this disease may suffer from nasal congestion due to the edema of nasal mucosa, which causes open-mouth breathing and snoring. The application of nasal glucocorticosteroids such as budesonide and other nasal sprays, as well as decongestants such as hydroxymetholazoline, can reduce nasal resistance and the vibration of the soft palate caused by the change of the negative and positive pharyngeal pressures during inhalation. 2. Obesity: patients with this symptom may have localized fat accumulation and pharyngeal collapse leading to snoring, which can be achieved by adjusting the sleeping position, trying to take the lateral position or prone position to reduce the fall of the tongue root; weight loss treatment for the obese; the use of oral orthodontic appliances and so on, or snoring can be reduced. 3. Deviated nasal septum: Due to nasal obstruction caused by deformation of nasal septum bone and cartilage, oral airflow vibration of pharyngeal wall mucosa and secretion can lead to snoring. Nasal septum correction surgery can correct the abnormal ventilation of upper airway, restore the smoothness of the oral and nasal airway, and reduce the pathological oscillation of soft palate. It is recommended that patients go to the hospital for consultation to clarify whether snoring is simple snoring or obstructive sleep apnea syndrome is triggered, and choose standardized medication and treatment according to the specific causative factors and the degree of symptoms.
