A 31-year-old woman presented with a complaint of hearing loss of a two-year history. Otoscopic examination revealed a central ear drum perforation without discharge. The air-bone gap was 35 dB at 0.5, 1, 2, and 3 kHz. Under general anesthesia, the patient underwent tympanoplasty for chronic otitis media. At surgery, the ossicular chain was intact except for discontinuity by a 2-mm gap between the long process of the incus and the head of the stapes. The gap was reconstructed with the use of a fluoroplastic prosthesis. Myringoplasty was successful, but the patient complained of hearing loss at the end of six months. Transcanal posterior tympanotomy was performed under local anesthesia for decreased conductive hearing. The prosthesis was still in place, but was not conducting the movements of the malleus to the stapes. It was removed and glass ionomer cement (Ketac-Cem) was applied for rebridging. The average air-bone gap measured in the postoperative sixth month was less than 10 dB.
一名31岁女性因听力损失两年前来就诊。耳镜检查发现中耳鼓膜中央穿孔,无分泌物。在0.5、1、2和3千赫兹频率下,气骨导差为35分贝。患者在全身麻醉下接受了慢性中耳炎鼓室成形术。手术中,听骨链完整,只是砧骨长突与镫骨头之间有2毫米的间隙导致连续性中断。使用氟塑料假体修复该间隙。鼓膜成形术成功,但患者在六个月后仍诉说听力损失。因传导性听力下降,在局部麻醉下进行了经耳道后鼓室切开术。假体仍在位,但无法将锤骨的运动传导至镫骨。将其取出,应用玻璃离子水门汀(Ketac-Cem)重新连接。术后第六个月测得的平均气骨导差小于10分贝。
