BACKGROUND Chronic otitis media with cholesteatoma requires surgical treatment. One technique used is radical modified mastoidectomy. However, if there is subsequent hearing loss, the patient will often need to be provided with a hearing prosthesis, and one option is to use a bone-anchored hearing device. One of the percutaneous bone-anchored hearing aids available in clinical practice is the Ponto system (Oticon Medical). MATERIAL AND METHODS There were 27 patients enrolled in this study (13 females, 14 males), all of whom had previously undergone radical modified mastoidectomy. They were implanted with the Ponto bone-anchored hearing device from Oticon Medical. The mean age of the subjects at implantation was 59 years (36-75 years, SD=11). Five patients had moderate conductive hearing loss in the implanted ear, and 22 had moderate to very severe mixed hearing loss. Benefits of the Ponto system were assessed using tone and speech audiometry (free-field), as well as with APHAB (Abbreviated Profile of Hearing Aid Benefit) and SSQ (Speech, Spatial and Qualities of Hearing Scale) questionnaires. RESULTS The Ponto system resulted in a statistically significant improvement in hearing sensitivity and speech discrimination. The questionnaires confirmed the benefits of the Ponto system under various acoustic conditions. CONCLUSIONS Ponto was found to be a safe and effective tool in compensating for conductive or mixed hearing loss after radical modified mastoidectomy. The system can provide good support for auditory function in people who are at risk of recurrent otitis media with cholesteatoma and who may therefore require subsequent revision or further surgical intervention.
背景 伴有胆脂瘤的慢性中耳炎需要手术治疗。一种常用的技术是改良根治性乳突切除术。然而，如果术后出现听力损失，患者通常需要佩戴听力假体，一种选择是使用骨锚式听力装置。临床实践中可用的经皮骨锚式助听器之一是Ponto系统（奥迪康医疗公司）。
材料与方法 本研究共纳入27例患者（13例女性，14例男性），所有患者均曾接受改良根治性乳突切除术。他们植入了奥迪康医疗公司的Ponto骨锚式听力装置。植入时受试者的平均年龄为59岁（36 - 75岁，标准差 = 11）。5例患者植入耳有中度传导性听力损失，22例有中度至极重度混合性听力损失。使用纯音和言语测听法（自由声场）以及APHAB（助听器效益简表）和SSQ（言语、空间和听力质量量表）问卷评估Ponto系统的效益。
结果 Ponto系统在听力敏感度和言语辨别方面有统计学意义的改善。问卷证实了Ponto系统在各种声学条件下的效益。
结论 发现Ponto是补偿改良根治性乳突切除术后传导性或混合性听力损失的一种安全有效的工具。该系统可为有复发性胆脂瘤型中耳炎风险、可能因此需要后续翻修或进一步手术干预的患者的听觉功能提供良好支持。
