To investigate the surgical and audiological outcomes in adult bone-anchored hearing system (BAHS) users who underwent implantation using a minimally invasive, single-drill procedure (MONO procedure).
Retrospective cohort design.
University hospital.
Adult subjects (≥18 yr), with conductive and mixed hearing loss, or single-sided deafness (SSD), who underwent BAHS surgery using MONO from 2021 to 2023.
BAHS implantation.
Surgical and postoperative complications were investigated during the entire follow-up period. Preoperative unaided air- and bone-conduction thresholds, pure-tone average (PTA), air-bone gap (ABG), and monosyllabic word recognition scores (unaided- and softband-aided) were compared with the postoperative BAHS aided PTA, remaining ABG, functional gain, and monosyllabic word recognition scores.
Forty-four subjects aged between 20 and 70 (52 ± 15) years met the inclusion criteria. One subject (2.3%) required two punch incisions due to implant instability during surgery. Two subjects (4.6%) experienced adverse skin reactions. Pain (6.9%) and moisture (6.9%) at implant site were also reported. No other complications were reported over a mean follow-up time of 12.2 ± 5.7 months. The mean BAHS aided score was significantly greater than the mean unaided- and softband-aided scores. All subjects showed functional improvements after surgery (25-31 dB), and the average effective gain was 1.3 dB.
The MONO procedure was shown to be a viable option for routine BAHS surgery in adults. The auditory performance of the subjects improved postoperatively, and complications were minimal and easily resolved. Further studies are required to investigate the long-term outcomes of MONO in this population.
4-Retrospective review.
探讨采用微创单钻孔手术（MONO手术）植入成人骨锚式听力系统（BAHS）的手术及听力学效果。
回顾性队列研究。
大学医院。
2021年至2023年期间接受MONO手术植入BAHS的成年受试者（≥18岁），患有传导性和混合性听力损失或单侧耳聋（SSD）。
植入BAHS。
在整个随访期间调查手术及术后并发症。比较术前未助听气导和骨导阈值、纯音平均听阈（PTA）、气骨导差（ABG）以及单音节词识别分数（未助听和软带助听）与术后BAHS助听PTA、剩余ABG、功能增益和单音节词识别分数。
44名年龄在20至70（52±15）岁之间的受试者符合纳入标准。1名受试者（2.3%）因手术期间植入物不稳定需要两个冲孔切口。2名受试者（4.6%）出现皮肤不良反应。还报告了植入部位的疼痛（6.9%）和潮湿（6.9%）。在平均12.2±5.7个月的随访时间内未报告其他并发症。BAHS助听平均分数显著高于未助听和软带助听平均分数。所有受试者术后均显示功能改善（25 - 31 dB），平均有效增益为1.3 dB。
MONO手术被证明是成人常规BAHS手术的可行选择。受试者的听觉性能术后有所改善，并发症极少且易于解决。需要进一步研究来调查MONO手术在该人群中的长期效果。
