The mucosal epithelium of the middle ear and Eustachian tube is in direct continuity with the upper respiratory tract. Since the otolaryngological aspects of cystic fibrosis (CF) are dominated by involvement of the paranasal sinuses, it might be assumed that children with CF would be expected to have a higher than usual incidence of middle ear disease. Eighty patients who were afflicted with CF had audiological evaluations, which consisted of hearing threshold levels (250 to 8,000 Hz) and speech and impedance audiometry. We found no greater incidence of a conductive or sensorineural hearing loss in patients with CF when compared with a normal age-adjusted population.
中耳和咽鼓管的黏膜上皮与上呼吸道直接相连。由于囊性纤维化（CF）的耳鼻喉科表现主要由鼻窦受累主导，因此可能会认为CF患儿中耳疾病的发病率会高于正常水平。80例CF患儿接受了听力评估，包括听阈水平（250至8000赫兹）以及言语和阻抗测听。与年龄匹配的正常人群相比，我们发现CF患者中传导性或感音神经性听力损失的发生率并无更高。
