气化差的乳突气房系统往往见于慢性中耳炎患者,然而气化差究系炎症的因或果仍有争论。作者曾根据用猪(猪中耳气房系统相似于人乳突气房系统)作实验研究,报告在生命早期的慢性中耳炎症抑制气化过程。本文则分析炎症的起病与气化程度的关系。作者用8只小猪,按实验性慢性中耳炎起病的时间分4组(每组2只):组1为出生后1周;组2出生后1月;组3出生后2月;组4出生后4月。所有猪的右耳为致炎耳,用纯甘油经鼓膜注入引起实验性中耳炎;各组的1只猪左耳为对照耳,
Poor gasification of the mastoid air chamber system is often found in patients with chronic otitis media, however, gasification difference is still due to inflammation or contention. Based on experimental studies using pigs (porcine middle ear atrial system similar to human mastoid air system), the authors report that chronic otitis media suppresses gasification during early life. This article analyzes the relationship between the onset of inflammation and the degree of gasification. The authors used 8 piglets divided into 4 groups (2 in each group) according to the onset of experimental chronic otitis media: group 1 was 1 week after birth; group 2 was born 1 month after birth; group 3 was born 2 months after birth; group 4 April after birth. The right ear of all pigs was caused by inflammatory ear, which was injected into the tympanic membrane with pure glycerol to induce experimental otitis media. The left ear of each pig was the control ear,
