To investigate the surgical and audiological outcomes of an installation of a bone-anchored hearing system (BAHS) procedure without tissue reduction using Ponto implants and abutments. Retrospective consecutive case series. Forty-nine patients, 18 years or older and eligible for treatment with a bone-anchored hearing system with tissue preservation surgery, were included in the study. Following a systematic scheme for medical outcomes, we collected the data regarding surgical intervention, quality of life (GBI), skin and soft tissue reactions (Holgers grading system), pain and numbness (VAS). Hearing performance (aided thresholds and speech recognition in noise) was recorded in 20 patients. No implants were lost, skin, and soft tissue reactions were mild in 96 % of the all visits. Quality of life (GBI) generally improved in the aided condition compared to prior to implantation. Audiologically, 100 % of the 20 patients examined showed improvement of speech reception and sound field thresholds comparing aided to unaided. An average improvement of 33 dB on PTA was recorded. The study, presenting data on a large population, treated with tissue preservation and modern titanium implants, shows that this treatment is a viable solution that results in fewer complications, high degree of predictability and good audiological results.
探讨使用Ponto种植体和基台进行无组织缩减的骨锚式听力系统（BAHS）植入手术的外科手术和听力结果。回顾性连续病例系列研究。本研究纳入了49例18岁及以上且符合采用保留组织的骨锚式听力系统治疗条件的患者。按照系统的医疗结果方案，我们收集了有关手术干预、生活质量（GBI）、皮肤和软组织反应（霍尔格斯分级系统）、疼痛和麻木（视觉模拟评分法）的数据。记录了20例患者的听力表现（助听阈值和噪声中的言语识别）。无种植体丢失，在所有就诊中，96%的患者皮肤和软组织反应轻微。与植入前相比，助听状态下的生活质量（GBI）总体有所改善。在听力方面，20例接受检查的患者中，100%的患者在助听与未助听时相比，言语接受和声场阈值均有改善。纯音平均听阈平均提高了33dB。该研究展示了大量采用保留组织和现代钛种植体治疗患者的数据，表明这种治疗是一种可行的解决方案，并发症较少，可预测性高，听力结果良好。
