慢性中耳炎患者,常有颞骨气房发育不良,一般认为慢性中耳炎和气房气化不良存在因果关系。然而,究竟是慢性中耳炎引起气房气化受阻,或是气房气化不良导致中耳炎症的发生和发展,尚无定论。作者用13头出生后7天内的颞骨气房气化尚未发育的仔猪,进行中耳感染和咽鼓管功能不全对乳突气房气化影响的实验性研究;实验Ⅰ组动物8头,从左咽鼓管口注入硅酮,造成咽鼓管狭窄,使中耳产生负压;实验Ⅱ组动物5头,经左鼓膜穿刺注入石蜡油,
Patients with chronic otitis media, often temporal atrioventricular dysplasia, chronic gastritis and chronic gastritis is generally believed that causal relationship exists. However, whether the chronic gastritis caused gasification blocked, or poor gasification of the middle ear caused by the incidence and development of inflammation, there is no conclusive. In this study, we used 13 experimental piglets of the temporal bone gasification of the undeveloped piglets within 7 days after birth to study the effects of middle ear infection and eustachian tube dysfunction on the gasification of the mastoid. Experimental group I 8 animals, Left eustachian tube into the silicone injection, resulting in eustachian tube stenosis, the middle ear to produce negative pressure; experimental group Ⅱ 5 animals, the left tympanic membrane into the paraffin oil,
