In cases of a severe to profound sensorineural hearing loss following head injury, the cochlear implant (CI) is the primary option for auditory rehabilitation. Few studies, however, have investigated long-term CI outcomes in patients following head trauma, including those without temporal bone fracture (TBF). Herein, the aim of this study is to examine CI outcomes following cases of head injury with and without TBF.
Audiometric outcomes of patients who received a CI due to a head injury resulting in severe to profound hearing loss at two tertiary care hospitals were analyzed. Patients were divided into those who received a CI in a fractured temporal bone (group A, n = 11 patients corresponding to 15 ears) and those who received a CI in a non-fractured temporal bone (group B, n = 8 patients corresponding to nine ears). Primary outcomes included duration of deafness prior to CI and postoperative consonant-nucleus-constant whole word (CNC) scores.
Nineteen patients (84% male), corresponding to 24 CIs, were identified. Fifteen CI were performed on ears with TBF (group A), and nine CI were performed on ears without TBF (group B). No patients had an enlarged vestibular aqueduct (EVA). The mean duration of deafness was 5.7 and 11.3 years in group A and group B, respectively. The mean duration of CI follow-up (CI experience) was 6.5 years in group A and 2.1 years in group B. The overall mean postoperative CNC score for all subjects was 68.6% (±21.2%, n = 19 with CNC testing). There was no difference in CNC score between group A and group B (69.8% and 66% respectively, = .639).
The study is among the largest series examining long-term outcomes of CI after head injury. CI is an effective method for auditory rehabilitation in patients after head injury.

对于头部受伤后出现重度至极重度感音神经性听力损失的病例，人工耳蜗植入（CI）是听觉康复的主要选择。然而，很少有研究调查头部外伤患者的人工耳蜗长期植入效果，包括那些没有颞骨骨折（TBF）的患者。在此，本研究的目的是检查有和没有颞骨骨折的头部受伤病例后的人工耳蜗植入效果。
分析了两家三级医院中因头部受伤导致重度至极重度听力损失而接受人工耳蜗植入的患者的听力测量结果。患者分为在骨折颞骨中接受人工耳蜗植入的患者（A组，n = 11例患者，对应15只耳）和在未骨折颞骨中接受人工耳蜗植入的患者（B组，n = 8例患者，对应9只耳）。主要结果包括人工耳蜗植入前的耳聋持续时间和术后辅音-核-恒定全词（CNC）得分。
确定了19例患者（84%为男性），对应24次人工耳蜗植入。15次人工耳蜗植入在有颞骨骨折的耳上进行（A组），9次人工耳蜗植入在没有颞骨骨折的耳上进行（B组）。没有患者有扩大的前庭导水管（EVA）。A组和B组的平均耳聋持续时间分别为5.7年和11.3年。A组人工耳蜗随访的平均持续时间（人工耳蜗使用经验）为6.5年，B组为2.1年。所有受试者术后的总体平均CNC得分为68.6%（±21.2%，n = 19例进行了CNC测试）。A组和B组的CNC得分没有差异（分别为69.8%和66%，P = 0.639）。
该研究是检查头部受伤后人工耳蜗长期效果的最大系列研究之一。人工耳蜗植入是头部受伤患者听觉康复的有效方法。
