Abstract

Objective: This study emphasizes the role of preoperative high-resolution computed tomography (HRCT) temporal bone in evaluating the variation in cochlear orientation and proposes a grading system to determine the level of intraoperative difficulties encountered.

Methods: Preoperative correlation of middle ear and inner ear structures along with the basal turn angle (BTA) was done to assess the orientation. Patients were divided into three groups depending on BTA and radiology findings.

Results: Group A (BTA = 55°-60°) had statistically significant (p < 0.05) correlation between middle ear to inner ear structures on HRCT, whereas group B (BTA >60°) and C (BTA <55°) had variations in the alignment of middle ear structures to their corresponding inner ear structures.

Conclusion: The association of BTA to the correlation between middle ear and inner ear structures can determine the orientation of the cochlea. This evaluation makes the surgeon aware of intraoperative challenges and helps in surgical planning.

术前颞骨 HRCT 对耳蜗方向的重要性及其与人工耳蜗植入术中困难的关系--预测困难等级。

目的：本研究强调术前高分辨率计算机断层扫描（HRCT）颞骨在评估耳蜗方位变化中的作用，并提出一个分级系统来确定术中遇到的困难程度：方法：术前对中耳和内耳结构以及基底转角（BTA）进行相关性分析，以评估方向。根据 BTA 和放射学检查结果将患者分为三组：结果：A 组（BTA = 55°-60°）和 C 组（BTA = 55°-60°）的 BTA 和放射学结果有显著的统计学意义（P 60°）：BTA 与中耳和内耳结构之间的相关性可以确定耳蜗的方向。这一评估使外科医生意识到术中的挑战，并有助于手术规划。

期刊介绍： Cochlear Implants International was founded as an interdisciplinary, peer-reviewed journal in response to the growing number of publications in the field of cochlear implants. It was designed to meet a need to include scientific contributions from all the disciplines that are represented in cochlear implant teams: audiology, medicine and surgery, speech therapy and speech pathology, psychology, hearing therapy, radiology, pathology, engineering and acoustics, teaching, and communication. The aim was to found a truly interdisciplinary journal, representing the full breadth of the field of cochlear implantation.
