一、鼻腔填塞对中耳压和咽鼓管功能的影响鼻腔填塞引起中耳压变化,从而影响咽鼓管功能。Bonding 等(1981)报告双侧前鼻填塞病人中有46％其中耳压降至-100mmH_2O 或以下,取除填塞迅速恢复。单侧前鼻填塞对中耳压无明显影响。单侧后鼻栓塞50％引起中耳压变 First, the impact of nasal packing on the middle ear pressure and Eustachian tube function Nasal packing caused by changes in the middle ear pressure, thus affecting Eustachian tube function. Bonding et al. (1981) reported that 46% of patients with bilateral anterior nasal obstruction had a reduction in middle ear pressure to -100 mmH 2 O or below, with rapid recovery after removal of the obstruction. Unilateral nasal packing had no significant effect on middle ear pressure. 50% of unilateral posterior nasal embolism caused by middle ear pressure
