Determine whether adult cochlear implant users with radiographic superior semicircular canal dehiscence experience clinically significant differences in audiological outcomes when compared to cochlear implant users with normal temporal bone anatomy.
Retrospective, single institution review. Adult, post-lingual deaf patients implanted between 2010 and 2020. Inclusion criteria included age 18 years or older, available preoperative computed tomography imaging, and preoperative and postoperative AzBio audiological data for at least 6 months of cochlear implant use. Preoperative and postoperative AzBio Sentence Test scores were compared between patients with normal temporal bone anatomy and those with radiographic superior semicircular canal dehiscence or near dehiscence.
110 patients met inclusion criteria. Mean AzBio score for normal temporal bone anatomy group improved from 35.2 % (SD 28.2) preoperatively to 70.3 % (SD 25.7) postoperatively, an improvement of 35.1 % (SD 28.6). Mean AzBio score for near dehiscent temporal bone anatomy group improved from 26.6 % (SD 28.9) preoperatively to 64.5 % (SD 30.6) postoperatively, an improvement of 37.9 % (SD 27.9). Mean AzBio score for dehiscent temporal bone anatomy group improved from 26.3 % (SD 20.4) preoperatively to 65.1 % (SD 27.6) postoperatively, an improvement of 38.7 % (SD 26.9). Utilizing the one-way analysis of variance test, there was no significant difference in audiologic outcomes between the three groups.
Patients with complete or near complete radiographic superior canal dehiscence at the time of cochlear implantation achieve similar improvements in speech perception scores compared to normal anatomy adult cochlear implant users.
比较影像学上表现为上半规管裂和正常颞骨解剖结构的成年人工耳蜗植入患者的听力结果，以确定前者是否存在临床上显著差异。
回顾性、单中心研究。纳入 2010 年至 2020 年期间植入人工耳蜗的成年、后天性聋患者。纳入标准为年龄 18 岁及以上，术前有计算机断层扫描影像学资料，且术前和术后至少有 6 个月的人工耳蜗使用的 AzBio 听力数据。比较正常颞骨解剖结构组和影像学上表现为上半规管裂或接近裂的患者术前和术后的 AzBio 短句测试评分。
符合纳入标准的患者共 110 例。正常颞骨解剖结构组的 AzBio 平均评分从术前的 35.2%（SD 28.2）提高到术后的 70.3%（SD 25.7），提高了 35.1%（SD 28.6）。颞骨接近裂组的 AzBio 平均评分从术前的 26.6%（SD 28.9）提高到术后的 64.5%（SD 30.6），提高了 37.9%（SD 27.9）。颞骨完全裂组的 AzBio 平均评分从术前的 26.3%（SD 20.4）提高到术后的 65.1%（SD 27.6），提高了 38.7%（SD 26.9）。利用单因素方差分析检验，三组患者的听力结果无显著差异。
在人工耳蜗植入时存在完全或接近完全的影像学上表现为上半规管裂的患者，其言语感知评分的改善与正常解剖结构的成年人工耳蜗植入患者相似。
