The universality of middle ear diseases in infants with cleft lip and palate is well known. Middle ear disease is causally related to an eustachian tube dysfunction due to anatomical variations of the tubal lumen or muscles. Endoscopy of the nasopharynx, microscopic examination and impedance measurement of the ear was performed in 53 children with cleft lip, alveolus and palate. Dynamic and static documentation was performed with a videocamera or a reflex camera. The pharyngeal port of the eustachian tube was mechanically obstructed by the lateral part of the cleft palate muscle in nearly all patients. The degree of the mechanical obstruction seemed to be related to the extent of the cleft. Furthermore there were less pathologic ear findings in patients with less obstructed pharyngeal ports of the eustachian tube.
唇腭裂婴儿中耳疾病的普遍性是众所周知的。中耳疾病与咽鼓管功能障碍存在因果关系，这是由于咽鼓管管腔或肌肉的解剖变异所致。对53例唇、牙槽突和腭裂患儿进行了鼻咽部内镜检查、耳部显微镜检查和阻抗测量。使用摄像机或反光相机进行动态和静态记录。几乎所有患者的咽鼓管咽口都被腭裂肌肉的外侧部分机械性阻塞。机械性阻塞的程度似乎与腭裂的范围有关。此外，咽鼓管咽口阻塞较轻的患者耳部病理表现较少。
