咽鼓管开放症是一常见病。多数患者为间歇性发作,不需特殊处理;仅少数症状严重者,须予治疗。作者应用腭帆张肌移位或切断术,使产生功能性咽鼓管闭塞以治本病。术中将翼突钩骨折并将腭帆张肌肌腱提过翼突钩,如仍觉有张力,则行切断术。13例(16耳)咽鼓管异常开放患者,术后平均随访2年,11耳(69%)永久地解除了症状,无并发症。5例无效。 Doyle和Rood指出,从解剖和功能上已证实,腭帆张肌有两纤维束,外侧束围绕翼突钩进入腭骨和腱膜。内侧束附着于咽鼓管外侧膜性壁的后1/3,与外侧束纤维相并列。然而,仍能见到内侧束的某些纤维终止于翼突内侧板的后外缘,
Eustachian tube disease is a common disease. Most patients with intermittent attacks, without special treatment; only a few severe symptoms, to be treated. The authors apply the parasellalocation muscle dislocation or surgery, so that functional eustachian tube occlusion in order to cure the disease. Surgery will be the wing fracture of the wing hook and the palatal Muscle tendon raised mention wing hook, if still feel a tension, the line cut off. Thirteen patients (16 ears) with open eustachian tube were followed up for an average of 2 years and 11 ears (69%) were permanently relieved of symptoms and no complications. 5 cases invalid. Doyle and Rood point out that anatomically and functionally, there are two fiber bundles in the palatal fan and the lateral bundles hook around the wing tab into the palatal bone and the aponeurosis. The inner bundle is attached to the posterior 1/3 of the outer membrane wall of the Eustachian tube, parallel to the outer bundle fibers. However, some of the fibers of the medial bundle can still be seen terminating at the posterior rim of the medial wing of the wing,
