摘要

目的

评估自动多模影像融合技术对人工耳蜗植入后电极蜗内位置评价的有效性、可靠性，并与传统影像融合重建技术相比较，讨论其在电极阶位判断中的临床价值和应用前景。

方法

回顾性分析2020年1月～2021年12月于上海交通大学医学院附属第九人民医院耳鼻咽喉头颈外科门诊随访调机的人工耳蜗植入患者，收集其术前电子计算机断层扫描（computed tomography，CT）、磁共振成像（magnetic resonance imaging，MRI）及术后CT的符合医学数字成像和通信协议（digital Imaging and communications in medicine，DICOM）的数据资料，排除有耳蜗畸形或蜗神经畸形的病例。由2位耳科医师分别用传统技术和定制耳科影像分析软件（耳科精细结构图像智能处理分析软件，V 1.0）进行自动影像融合、重建及分析，评估电极位置（植入深度、电极阶位），并记录评价时间。

结果

共68例患者（109耳）纳入本研究（男32，女36），平均年龄5.1±13.1岁。所有电极均全植入，无电极打折，1例（0.9%）发生电极穿阶，7例（6.4%）发生基底膜移位。两种评价技术下，电极深度测量一致性良好［ICC=0.0999（95%CI 0.999～1.000），

0.001］，电极异常阶位范围测量一致性良好［ICC=0.0999（95%CI 0.999～1.000），

0.001］。自动影像融合软件的平均评价时间为10.0±1.8分钟，相较于传统方法（30.0±4.0分钟）显著缩短（

0.001）。不同类型电极间评价时间有差异，其中抱轴电极的评价时间较长，（

=3.610，

=0.016）。

结论

不同评价者使用自动影像融合技术的重复性良好，与传统方法的一致性良好，大幅缩短评价时间，有利于普及人工耳蜗植入术后影像学分析，可作为一种新技术在临床上推广。

Abstract

Objective

To evaluate the effectiveness and reliability of automatic imaging fusion technique in evaluating scalar position after cochlear implantation

and compare it with the "gold standard" of traditional imaging reconstruction technology

and discuss its clinical value and application prospect.

Methods

The patients' digital data of preoperative computed tomography (CT)

magnetic resonance imaging (MRI) and postoperative CT were collected

who received mapping in the Department of Otorhinolaryngology

Head and Neck Surgery

the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from Jan 2020 to Dec 2021. Two senior otologists assessed the scalar position after cochlear implantation using both traditional image reconstruction technique and automatic imaging fusion reconstruction techniques (MUSARIO

Medical ultra-structure analysis and reconstruction software in otology

V 1.0). The insertion depth

scalar position and evaluation time were collected.

Results

68 patients with 109 ears were included in the study

32 males and 36 females

with average age 5.1±13.1 yrs. All electrode arrays were fully inserted without fold. The basilar membrane shift happened in 7 cases (6.4%)

and 1(0.9%) case presented translocation. Measured by two methods

there was good consistency with the insertion depth [ICC=0.0999 (95%CI 0.999-1.000)

0.001] and range of electrodes with basilar membrane shift or translocation [ICC=0.0999 (95%CI 0.999-1.000)

0.001]. The mean measurement time was 30±4.0 minutes with traditional technique and 10±1.8 minutes with MUSARIO

respectively (

0.001). The evaluation times of different types of electrodes were different

and the evaluation time of pre-curved electrode is longer (

=3.610

=0.016).

Conclusion

As a new technique

automatic imaging fusion reconstruction technique has no difference in reliability compared with traditional image reconstruction technique. It greatly shortens the evaluation time and is beneficial to popularize the imaging analysis after cochlear implantation. It can be clinically promoted as a new technology.
