作者们借助显微手术于门诊修复外伤性鼓膜穿孔10例。年龄17～51岁,男3女7。手术器械:手术显微镜、扩大耳镜、耳用吸引管、耳科显微手术用各种针、外耳道异物钩、微型耳钳。为减少感染机会无需麻醉。除一例耳漏者外均未使用抗生素,亦未进行局部消毒。术式:在手术显微镜下仔细观察鼓膜,吸除异物及过多的血液。注意勿强烈吸引以免吸掉鼓膜瓣。穿孔时负压与正压交互作用,使破损鼓膜瓣或翻向外耳道或翻向鼓室。翻向外耳道者易找到其游离缘,可用针尖轻拨之复位;翻向鼓室者则常贴附鼓膜内面或卷到听骨上,需用呈直角弯针在鼓膜内面耐 The authors used microsurgery in the outpatient repair of traumatic tympanic membrane perforation in 10 cases. Age 17 ~ 51 years old, male 3 female 7. Surgical instruments: surgical microscope, to expand the otoscope, ear suction tube, ear acupuncture microsurgery with a variety of foreign body ear hook foreign body, miniature ear forceps. No anesthesia needed to reduce the chance of infection. No antibiotics were used except one case of ear leaks and no local disinfection. Surgery: Carefully observe the tympanic membrane under the surgical microscope, aspiration of foreign body and excessive blood. Be careful not to attract strongly to avoid aspiration of the tympanic membrane. Perforated negative pressure and positive pressure interaction, so that damage to the tympanic membrane flap or turn to the external auditory canal or turn to the tympanic cavity. Flip to the external ear canal easy to find its free edge can be used to reset the needle tip; turn to the tympanic membrane are often attached to the inner surface of the tympanic membrane or roll to the ossicles, the need to use a right angle lobe in the tympanic membrane surface resistance
