Bone anchored hearing solutions are a well-known option for patients with a conductive, mixed conductive-sensorineural hearing loss and those with single-sided deafness. The aim of the present study was to evaluate the Ponto bone-anchored hearing system in terms of behavioral performance and self-reported outcomes, by comparing unaided and aided performance (softband and abutment), as well as aided performance with the sound processor on softband (preoperatively) versus abutment (postoperatively). Fourteen adult bone-anchored candidates, with either a bilateral ( = 12) or unilateral ( = 2) conductive or mixed hearing loss, participated in the present study. Sound-field hearing thresholds were evaluated unaided and aided (softband and abutment). A speech-in-noise test was also performed unaided and aided for two spatial configurations (S0N90; implanted side; S0N90; nonimplanted side). The Glasgow Health Status Inventory and the Speech, Spatial and Quality of sound questionnaires were administered pre- and postsurgery to compare quality of life and perceived unaided and aided performance. Skin reaction (Holgers scores) was evaluated at 15 days, 6 weeks, and 10 weeks after surgery. Significant improvements postoperatively relative to unaided were obtained for sound-field thresholds at all tested frequencies. Additionally, sound-field thresholds were significantly improved with the sound processor on abutment relative to the softband at frequencies > 1 kHz. Improved performance postoperatively relative to unaided was also obtained in the speech-in-noise test and in self-reported outcomes. Improvements in behavioral performance and self-reported outcomes were obtained with the sound processor mounted on abutment.
骨锚式听力解决方案对于患有传导性、混合性传导性-感音神经性听力损失的患者以及单侧耳聋患者来说是一种广为人知的选择。本研究的目的是通过比较未佩戴辅助装置和佩戴辅助装置（软带和基台）时的行为表现以及自我报告结果，评估Ponto骨锚式听力系统，同时比较术前软带佩戴声音处理器与术后基台佩戴声音处理器时的辅助表现。14名患有双侧（n = 12）或单侧（n = 2）传导性或混合性听力损失的成年骨锚式听力植入候选者参与了本研究。评估了未佩戴辅助装置和佩戴辅助装置（软带和基台）时的声场听力阈值。还针对两种空间配置（S0N90；植入侧；S0N90；非植入侧）进行了未佩戴辅助装置和佩戴辅助装置时的噪声中言语测试。在手术前后发放了格拉斯哥健康状况量表以及言语、空间和声音质量问卷，以比较生活质量以及感知到的未佩戴辅助装置和佩戴辅助装置时的表现。在术后15天、6周和10周评估皮肤反应（霍尔格斯评分）。与未佩戴辅助装置相比，术后所有测试频率的声场阈值均有显著改善。此外，在频率>1kHz时，与软带相比，基台佩戴声音处理器时的声场阈值有显著改善。在噪声中言语测试和自我报告结果方面，与未佩戴辅助装置相比，术后也有改善。基台佩戴声音处理器时，行为表现和自我报告结果均得到改善。
