The postnasal drip(PND) is an important feature of chronic sinusitis(CS). PND frequently causes abnormal sensations in the nasopharynx, cough, and sputum. The viscosity and the elasticity of the nasal mucus of CS patients has been found to be much higher than in normal　subjects. This means that the　nasal mucus of patients is stiffer and more elastic, and　this results in a rope of mucus streching form a sinus ostium along the mucus path into the nasopharynx. Hyperplasia and hypertrophy of glands in the nasal and sinus mucosa cause the hypersecretion of mucus. This phenomenon also contributes to the etiology of PND . Mucociliary clearance occurs form the anterior to the posterior part of the nose,　and clearance was slower in about half of the patients. Under these circumstnces,nasal mucus is retained in nasal cavity and drips into the nasopharynx when the quantity of the retaind mucus increases.
