This study aims to investigate the application value of magnetic resonance (MR) hydrography of the inner ear in cochlear implantation.
146 patients were enrolled. MR hydrography and spiral CT examinations for the intracranial auditory canal were performed before surgery, and all imaging results were statistically analyzed in order to explore the application value of MR hydrography of the inner ear in cochlear implantation.
146 patients (292 ears) were examined. Among these patients, 13 were diagnosed with abnormal vestibular aqueducts (20 ears) by MR hydrography, while five were diagnosed with this disease by CT; 15 patients were diagnosed with inner ear malformation (19 ears) by MR hydrography, while 11 were diagnosed by CT (four were misdiagnosed); five patients were diagnosed with internal acoustic canal stenosis (eight ears) by MR hydrography, while two were diagnosed by CT (three were misdiagnosed); and four patients were diagnosed with cochlear fibrosis (five ears) by MR hydrography, while four were diagnosed by CT (four ears). The correct rate of diagnosis was 77.40% (113/146) based on CT, while the rate was 93.84% (137/146) based on MR hydrography.
MR hydrography imaging technique can be applied to the preoperative evaluation of cochlear implantation, providing accurate and reliable anatomic information on the inner membranous labyrinth and nerves in the internal acoustic canal and an accurate basis for the diagnosis of cochlear fibrosis and nerve development. This has a guiding significance for the selection of treatment schemes.
本研究旨在探讨内耳磁共振水成像（MR）在人工耳蜗植入中的应用价值。
纳入146例患者。术前对颅内耳道进行MR水成像和螺旋CT检查，并对所有影像学结果进行统计学分析，以探讨内耳MR水成像在人工耳蜗植入中的应用价值。
对146例患者（292耳）进行了检查。在这些患者中，MR水成像诊断出13例前庭导水管异常（20耳），而CT诊断出5例；MR水成像诊断出15例内耳畸形（19耳），而CT诊断出11例（4例误诊）；MR水成像诊断出5例内耳道狭窄（8耳），而CT诊断出2例（3例误诊）；MR水成像诊断出4例耳蜗纤维化（5耳），而CT诊断出4例（4耳）。基于CT的诊断正确率为77.40%（113/146），而基于MR水成像的诊断正确率为93.84%（137/146）。
MR水成像技术可应用于人工耳蜗植入的术前评估，为内耳膜迷路和内耳道神经提供准确可靠的解剖信息，为耳蜗纤维化及神经发育的诊断提供准确依据。这对治疗方案的选择具有指导意义。
