Recently, the use of transcutaneous bone conduction implants (BCIs) has been increased. However, scarce data about BCI hearing recovery in noise conditions have been reported.
To investigate the audiological benefits obtained with transcutaneous BCI-Sophono Alpha System in noise conditions. To evaluate post-implantation clinical outcomes and patient satisfaction levels.
Fourteen patients suffering from conductive or mixed hearing loss implanted with the Sophono Alpha System were evaluated. Patients underwent physical examination, free-field pure-tone and speech audiometry both in unaided and aided conditions. The matrix sentence test was employed with fixed noise at 65 dB, and with a fluctuating primary signal, in three different conditions of noise presentations (S0/N0, S0/Ncontra, S0/Nipsi).
Hearing gain, expressed as the difference between pre-implant AC and post-implant SAS free field, was on average 26.7 dB. The unaided speech recognition score in quiet conditions had a mean value of 64.6%, and improved after SAS implantation, achieving mean values of 98.2%. SRT with the matrix sentence test improved in all three conditions of noise presentation.
Sophono Alpha System devices represent a valid treatment option for hearing rehabilitation of patients with conductive or mixed hearing loss. The audiological results regarding hearing gain in noise conditions were good.
最近，经皮骨传导植入物（BCI）的使用有所增加。然而，关于BCI在噪声环境中听力恢复的报道数据稀少。
研究经皮BCI-Sophono Alpha系统在噪声环境中获得的听力学益处。评估植入后的临床结果和患者满意度水平。
对14例植入Sophono Alpha系统的传导性或混合性听力损失患者进行评估。患者在未佩戴辅助设备和佩戴辅助设备的情况下均接受了体格检查、自由声场纯音听力测试和言语听力测试。矩阵语句测试在65dB的固定噪声下进行，并在三种不同的噪声呈现条件（S0/N0、S0/N对侧、S0/N同侧）下使用波动的主信号。
听力增益以植入前气导（AC）和植入后骨锚式助听器（SAS）自由声场之间的差异表示，平均为26.7dB。安静条件下未佩戴辅助设备时的言语识别得分平均值为64.6%，在植入SAS后有所改善，平均值达到98.2%。矩阵语句测试的言语接受阈（SRT）在所有三种噪声呈现条件下均有所改善。
Sophono Alpha系统设备是传导性或混合性听力损失患者听力康复的有效治疗选择。在噪声环境中听力增益方面的听力学结果良好。
