对36例鼓膜中央性穿孔成年患者采用硬管内窥镜经外耳道行鼓膜成形术的作用进行评价。对诊断为鼓膜中央部干性穿孔的患者,先用测压法、内窥镜法及声阻抗测听仪检查咽鼓管功能。将长18cm、外周直径4.0mm、倾斜角为0°、30°、70°的Storzy硬管内窥镜通过外耳道观察鼓膜穿孔、残边、中耳粘膜、咽鼓管开口及听骨链情况,对外耳道狭窄的病人使用外周径2.7mm内窥镜。将内窥镜插入并检查
Thirty-six patients with central perforation of the tympanic membrane were evaluated by the endoscopic eardrum tympanoplasty with endoscopic canalization. Patients diagnosed with dry perforation of the central portion of the tympanic membrane should first be examined for Eustachian tube function using manometry, endoscopy, and acoustic impedance audiometry. The perforation, remnants, middle ear mucosa, eustachian tube opening and ossicular chain were observed through the external auditory canal using a Storzy tube endoscope with a length of 18 cm, a diameter of 4.0 mm and a tilt angle of 0 °, 30 ° and 70 °. Patients with narrowing of the auditory canal use a 2.7mm diameter endoscope. Insert and check the endoscope
