Eustachian tube function was assessed by tympanometry in 47 patients (94 ears) with anterior nasal packing placed after nasal surgery and in 12 patients (24 ears) requiring anterior and posterior packing for epistaxis. Twenty-four of the 94 ears (25.5%) in patients with anterior packing exhibited reductions in middle ear pressure (greater than or equal to --100 mm H2O), whereas 12 of 13 ears (92.3%) ipsilateral to and six of 11 ears (45.4%) contralateral to the posterior pack demonstrated comparable reductions in middle ear pressure. The observation that posterior packing is associated with a greater incidence of eustachian tube dysfunction than anterior packing suggests that the mechanism of this dysfunction may be related to stasis in the peritubal lymphatic plexus rather than to nasal obstruction per se.
通过鼓室导抗图对47例（94耳）鼻手术后行前鼻孔填塞的患者以及12例（24耳）因鼻出血需行前后鼻孔填塞的患者的咽鼓管功能进行了评估。前鼻孔填塞患者的94耳中有24耳（25.5%）中耳压力降低（大于或等于-100 mm H₂O），而后鼻孔填塞同侧的13耳中有12耳（92.3%）、对侧的11耳中有6耳（45.4%）中耳压力有类似降低。后鼻孔填塞比前鼻孔填塞导致咽鼓管功能障碍发生率更高这一观察结果表明，这种功能障碍的机制可能与咽鼓管周围淋巴丛的淤滞有关，而非单纯与鼻阻塞有关。
