鼻出血或鼻腔、鼻窦手术后常需进行鼻腔填塞止血.此时患者因鼻腔通气受阻,可影响咽鼓管功能及鼓室压变化.为了探讨填塞后咽鼓管气压调节、引流受影响的程度,我们对50例鼻腔、鼻窦手术后行双侧鼻腔填塞及2例鼻出血、鼻咽部手术后行前后(单侧)鼻孔填塞, Epistaxis or nasal sinus surgery often require nasal packing to stop bleeding.At this time due to nasal ventilation blocked patients, can affect the eustachian tube function and tympanic pressure changes.In order to explore the eustachian tube pressure regulation after drainage, the degree of drainage affected, We performed 50 cases of nasal and sinus surgery after bilateral nasal packing and 2 cases of nasal bleeding, nasal pharyngeal surgery before and after (unilateral) nasal packing,
