There is very little information in the literature regarding outcomes of cochlear implantation in patients profoundly deafened after head injury. The aim of this study was to assess outcomes in this group of patients.
Retrospective case review.
The Manchester Cochlear Implant Programme, University of Manchester.
Profoundly deafened patients after head injury who proceeded to cochlear implantation for auditory rehabilitation.
Mean age and duration of deafness at implantation. Preimplantation and postimplantation speech perception outcomes were measured using Bench Kowel Bamford (BKB) sentences in quiet and noise, City University of New York sentences with lip reading and Arthur Boothroyd words scoring the percentage phonemes correct.
Twenty patients received 23 cochlear implants. Mean age at implantation was 51 years (standard deviation, 12 yr). Mean duration of deafness at implantation was 12 years (range, 1-30 yr).Preimplantation BKB score in quiet of 0%. Mean postimplantation BKB score in quiet was 64% (range, 0%-100%) and in noise was 61% (range, 0%-97%). Three were nonusers, and 1 required reimplantation. There was a moderately negative correlation between outcome and age at implantation (r = -0.41, p < 0.05) and between outcome and duration of deafness (r = -0.52, p < 0.05).
Cochlear implantation is an effective method for hearing rehabilitation in profoundly deafened patients after head injury. However, negative factors, such as significant injury to the central auditory pathway, basal turn obliteration, long duration of deafness, and nonauditory stimulation, should be considered in the preoperative assessment of these patients.
关于颅脑损伤后极重度聋患者行人工耳蜗植入的预后资料十分有限。本研究旨在评估此类患者的预后。
回顾性病例研究。
曼彻斯特人工耳蜗植入项目，曼彻斯特大学。
颅脑损伤后极重度聋患者，行人工耳蜗植入以进行听觉康复。
植入时的平均年龄和耳聋持续时间。使用 Bench Kowel Bamford（BKB）句子在安静和噪声中、纽约城市大学句子配合唇读以及 Arthur Boothroyd 单词测试正确音素百分比来评估植入前和植入后的言语感知结果。
20 例患者共植入 23 个人工耳蜗。植入时的平均年龄为 51 岁（标准差，12 岁）。植入时耳聋的平均持续时间为 12 年（范围，1-30 年）。植入前 BKB 安静测试得分为 0%。平均植入后 BKB 安静测试得分为 64%（范围，0%-100%），噪声环境下得分为 61%（范围，0%-97%）。3 例患者为非使用者，1 例需要再次植入。术后结果与植入时的年龄（r = -0.41，p < 0.05）和耳聋持续时间（r = -0.52，p < 0.05）呈中度负相关。
人工耳蜗植入是颅脑损伤后极重度聋患者进行听力康复的有效方法。然而，术前评估这些患者时应考虑到一些负面因素，如中枢听觉通路的严重损伤、基底转管闭塞、耳聋持续时间长以及非听觉刺激等。
