通过动物鼓室插管,研究其对中耳渗液的影响。用20只500克体重的健康灰鼠,右耳鼓室插管,左耳作对照,次日,劈开并去除部分软腭,每三天用耳镜观察鼓膜情况。将鼠分别于裂腭后1、5、10、21天杀死,有渗液者作鼓膜穿刺取中耳渗液作细菌培养,死后颞骨做病理检查。所有未插管耳,在裂腭24小时内耳镜检查有渗液;插管耳鼓膜为正常术后观,一耳于三天后发生化脓性耳漏。所有杀死鼠未插管耳证实有中耳渗
Through the animal intubation, to study its effect on the middle ear effusion. With 20 500 g body weight healthy squirrels, right ear drum intubation, left ear as a control, the next day, cleavage and removal of some soft palate, the eardrum observed every three days eardrum conditions. The mice were killed on the 1st, 5th, 10th and 21st days after the cleft palate respectively, and the effusion was taken as the tympanic membrane puncture for middle ear exudate for bacterial culture. After the death, the temporal bone was examined by pathology. All non-intubated ear, within 24 hours of cleft palate otoscopy exudate; intubation eardrum for normal postoperative view, one ear after three days of purulent otorrhea. All killed mice without intubation confirmed middle ear bleed
