BACKGROUND
The aim of this study is to investigate the clinical effectiveness of Ponto in Korea, a recently released percutaneous bone-anchored hearing implant.
METHODS
16 patients with single-sided deafness (SSD) and mixed or conductive hearing loss who underwent Ponto implantation from December 2018 to September 2020 were enrolled in the study. Puretone audiometry, the Korean version of the Hearing in Noise Test (K-HINT), sound localization test (SLT), and Pupillometry were performed pre- and three months post-operation. Standardized questionnaires, the Hearing Handicap Inventory for the Elderly (HHIE) and Speech, Spatial and Qualities of Hearing Scale (SSQ), were administered.
RESULTS
The mean age of subjects was 55.5 (range, 48-67) years. Four males and 12 females participated in the study. The mean puretone average was 73.17 dB hearing level (HL) before surgery and significantly improved to 36.72 dB HL three months after surgery. The mean word recognition score improved from 26.0% to 90.75% after implantation. In the case of K-HINT, there was a significant difference in summation (Z = -2.250, = 0.024) and head shadow effects (Z = -3.103, = 0.002). There was no significant difference in root mean square error degree (RMSE) and hemifield identification scores for SLT testing. Pupillometry was performed to measure listening effort and the results revealed that the degree of pupillary dilatation decreased under the condition of quiet, 0 dB signal to noise ratio (SNR) and 3 dB SNR. The total score for HHIE decreased significantly ( = -3.130, = 0.002) while the SSQ score increased significantly ( = -2.216, = 0.027).
CONCLUSIONS
The Ponto bone-anchored hearing system showed significant clinical benefit in Korean patients with conductive and mixed hearing loss and SSD.
背景
本研究旨在探讨韩国最新推出的经皮骨锚式听力植入体 Ponto 的临床疗效。
方法
本研究纳入了 2018 年 12 月至 2020 年 9 月期间接受 Ponto 植入术的 16 例单侧聋（SSD）和混合性或传导性听力损失患者。术前和术后 3 个月分别进行纯音测听、韩国版噪声下言语测听（K-HINT）、声源定位测试（SLT）和瞳孔测量。同时采用老年人听力障碍问卷（HHIE）和言语、空间和听觉质量量表（SSQ）进行标准化问卷调查。
结果
受试者的平均年龄为 55.5 岁（范围 48-67 岁），男性 4 例，女性 12 例。术前平均纯音平均听阈为 73.17dB 听力级（HL），术后 3 个月显著改善至 36.72dB HL。植入术后言语识别率从 26.0%提高至 90.75%。在 K-HINT 方面，和值（Z=-2.250， =0.024）和头部阴影效应（Z=-3.103， =0.002）有显著差异。SLT 测试的均方根误差（RMSE）和半视野识别评分无显著差异。进行瞳孔测量以评估听力努力程度，结果表明在安静、0dB 信噪比（SNR）和 3dB SNR 条件下，瞳孔扩张程度减小。HHIE 总分显著降低（ =-3.130， =0.002），SSQ 评分显著升高（ =-2.216， =0.027）。
结论
Ponto 骨锚式听力系统在韩国传导性和混合性听力损失及 SSD 患者中具有显著的临床获益。
