Head trauma often leads to bilateral sensorineural hearing loss (SNHL), and determining the optimal side for cochlear implantation (CI) remains a critical issue that requires further investigation. Objective: To evaluate the role of preoperative aided threshold (AT) testing in selecting the optimal CI side for patients with bilateral SNHL caused by head trauma.
This study included 9 patients with bilateral SNHL resulting from head trauma. Preoperative audiological and radiological evaluations were performed. The correlation between preoperative AT, duration of deafness (DoD), radiological findings, and Nijmegen Cochlear Implant Questionnaire (NCIQ) scores was analyzed.
Preoperative AT showed a tendency for a negative correlation with advanced sound perception scores (r = -0.740, = 0.057), while DoD exhibited a significant negative correlation with auditory self-confidence (r = -0.803, = 0.029). Imaging combined with AT provides a foundational framework for selecting the implantation side; however, the limited sample size restricts the generalizability of the findings.
Lower preoperative AT and shorter DoD may predict better auditory rehabilitation outcomes following CI. It is recommended to integrate imaging and audiological evaluations for individualized decision-making. Future studies with larger sample sizes are necessary to validate these findings and explore the clinical implications of early CI.
头部创伤常导致双侧感音神经性听力损失（SNHL），确定人工耳蜗植入（CI）的最佳侧别仍是一个需要进一步研究的关键问题。目的：评估术前助听阈值（AT）测试在为头部创伤所致双侧SNHL患者选择最佳CI侧别中的作用。
本研究纳入9例因头部创伤导致双侧SNHL的患者。进行了术前听力学和影像学评估。分析术前AT、耳聋持续时间（DoD）、影像学检查结果与奈梅亨人工耳蜗植入问卷（NCIQ）得分之间的相关性。
术前AT与高级声音感知得分呈负相关趋势（r = -0.740，P = 0.057），而DoD与听觉自信心呈显著负相关（r = -0.803，P = 0.029）。影像学检查结合AT为选择植入侧别提供了一个基础框架；然而，样本量有限限制了研究结果的普遍性。
较低的术前AT和较短的DoD可能预示着CI术后更好的听觉康复效果。建议结合影像学和听力学评估进行个体化决策。有必要开展更大样本量的未来研究以验证这些结果并探索早期CI的临床意义。
