传统上,外淋巴瘘(PLF)的确诊需要反复鼓室探查,而术中注入麻醉剂和渗出物的抽吸妨碍了PLF的准确诊断。文章比较PLF的内窥镜和手术探查的不同结果,指出中耳内窥镜可作为改善诊断PLF客观性的方法。方法:全麻,鼓膜作一辐射状切口,0°或30°1.9mmHopkins内窥镜进达中耳,当看见两窗无液体积存,通过麻醉师增加患者胸腔压力数次。内窥镜检查完后,行外耳道局麻,向前掀起鼓膜耳道皮瓣,显微镜下观察卵圆窗和圆窗。本文对3例PLF患者作了内窥镜
Traditionally, the diagnosis of a perilymph fistula (PLF) requires repeated tympanometry, while intraoperative anesthesia and exudate aspiration prevent the accurate diagnosis of PLF. The article compared the different results of PLF endoscopy and surgical exploration and pointed out that the middle ear endoscope can be used as a method to improve the objectivity of PLF diagnosis. Methods: General anesthesia, tympanic membrane for a radial incision, 0 ° or 30 ° 1.9mmHopkins endoscopy into the middle ear, when you see the two windows without liquid accumulation, by increasing the patient’s thoracic pressure several times. Endoscopy, the external auditory canal local anesthesia, set aside the tympanic membrane ear canal flap, under the microscope oval window and round window. In this paper, 3 cases of PLF patients made endoscopy
