The symptoms of snoring will appear when patients are sleeping flat on their backs, mainly because the posture of sleeping flat on their backs is prone to falling back, which will cause the respiratory passages in the throat to become narrower, affecting the normal respiratory ventilation, and will easily trigger the symptoms of snoring. If the patient adopts the sleeping position of side-lying, it can help to reduce the factor of falling back of the tongue root, and reduce the obstruction of the respiratory passage in the throat area, which will improve the degree of snoring to a certain extent. For patients with snoring symptoms, it is necessary to further improve the detailed examination of the entire upper respiratory tract, usually in the form of electronic nasopharyngoscopy, and it is also often necessary to further do the sleep monitoring examination, to comprehensively determine the specific causes of snoring and the degree of inflammation of snoring, and then take targeted treatment and improvement measures.
