OBJECTIVES/HYPOTHESIS: The purpose of the present study was to show our preliminary results regarding the endoscopic ear surgery application in malleostapedotomy surgery.
Case series.
Six patients (four females and two males) who underwent endoscopic ear surgery as revision surgery for otosclerosis were enrolled in this study. For endoscopic malleostapedotomy surgery, rigid angled endoscopes at 0 ° and 30 ° with a length of 14 cm and an outer diameter of 3 and 4 mm were used. A superelastic nitinol stapes prosthesis was used to connect the malleus neck to the oval window.
During endoscopic ear surgery, a lateral ossicular chain fixation was present in all cases. The mean operative time in the study group was 81 minutes (range, 73-89 minutes). A statistically significant difference between preoperative and postoperative hearing findings was observed (P = .007). No cases of sensorineural hearing loss or persistent vertigo were observed in the study sample. No cases of prosthesis displacement or prosthesis extrusion occurred after a mean follow-up of 11.5 months.
In 100% of treated cases, the endoscope proved to be adequate for the visualization of the malleus handle and incus, and of their possible abnormalities. Despite the difficulty related to endoscopic single-handed work, none of the surgical steps of endoscopic malleostapedotomy were considered not feasible by endoscopic ear surgery.
目的/假设：本研究的目的是展示我们在内镜耳手术应用于镫骨切除术方面的初步结果。
病例系列研究。
本研究纳入了6例接受内镜耳手术作为耳硬化症翻修手术的患者（4例女性和2例男性）。在内镜镫骨切除术手术中，使用了长度为14厘米、外径分别为3毫米和4毫米的0°和30°硬性角形内镜。使用超弹性镍钛合金镫骨假体将锤骨颈连接到椭圆窗。
在内镜耳手术期间，所有病例均存在外侧听骨链固定。研究组的平均手术时间为81分钟（范围为73 - 89分钟）。术前和术后听力检查结果之间观察到统计学上的显著差异（P = 0.007）。研究样本中未观察到感音神经性听力损失或持续性眩晕病例。平均随访11.5个月后，未发生假体移位或假体脱出病例。
在100%的治疗病例中，内镜被证明足以观察锤骨柄和砧骨及其可能的异常情况。尽管内镜单手操作存在困难，但内镜镫骨切除术的任何手术步骤在内镜耳手术中都不被认为不可行。
