The objective of this study is to retrospectively analyze the imaging characteristics of patients with congenital aural atresia who underwent Vibrant Soundbridge implantation, and to investigate the importance of preoperative evaluation of vibroplasty.
The study included 16 patients with bilateral congenital aural atresia aged 6-25 years (mean age, 14.7 years). All patients underwent Vibrant Soundbridge implantations.
Among the 16 patients, 15 successfully underwent stapes implantation. The average height of the stapes of these 15 patients was 2.93 mm, which was significantly different from that of the control group with normal hearing (p ≤ .001). The average distance between the tympanic segment of the facial nerve and the stapes was 1.41 mm in patients in whom the oval window was occluded by the displaced facial nerve. In the non-occluded group, the average distance was 2.00 mm. No significant difference was observed between the two groups (p = .08).
The distance between the facial nerve and stapes, as well as the height of the stapes, could be important predictors of successful stapes implantation of Vibrant Soundbridge.
本研究旨在回顾性分析接受振动声桥植入术的先天性外耳道闭锁患者的影像学特征，并探讨术前镫骨成形术评估的重要性。
本研究纳入了16例年龄在6至25岁（平均年龄14.7岁）的双侧先天性外耳道闭锁患者。所有患者均接受了振动声桥植入术。
16例患者中，15例成功进行了镫骨植入。这15例患者的镫骨平均高度为2.93毫米，与听力正常的对照组相比有显著差异（p≤0.001）。在椭圆形窗口被移位的面神经阻塞的患者中，面神经鼓室段与镫骨之间的平均距离为1.41毫米。在未阻塞组中，平均距离为2.00毫米。两组之间未观察到显著差异（p = 0.08）。
面神经与镫骨之间的距离以及镫骨的高度可能是振动声桥镫骨植入成功的重要预测指标。
