在日本的第一例病例报告中，我们描述了2例使用骨传导助听器和皮肤穿透植入物或骨锚式助听器（BAHA）治疗的患者。两人都患有慢性中耳炎，并接受了双侧管下鼓室乳突切除术。病例1为61岁女性，右耳佩戴传统空气传导助听器。两耳均无耳分泌物。纯音平均值为右耳82.5dBHL（空气），44.3dBHL（骨），左耳93.8dBHL（空气），48.8dBHL（骨）。病例2是一名38岁的女性，左耳佩戴传统助听器，持续性耳分泌物。纯音平均值为右耳48.8dBHL（空气），15.0dBHL（骨），左耳60.0dBHL（空气），20.0dBHL（骨）。两例患者均接受了右耳BAHA植入，术后随访9个月无不良反应。BAHA和空气传导助听器之间的辅助听力水平或言语辨别评分没有差异，但两名患者都更喜欢BAHA，因为它更舒适和可听度。
In this first case report in Japan, we described 2 patients treated using a bone conductive hearing aid with skin-penetrating implant, or bone-anchored hearing aid (BAHA). Both suffered from chronic otitis media and had received bilateral canal down tympanomastoidectomy. Case 1 was a 61-year-old woman with a conventional air conductive hearing aid in her right ear. There was no aural discharge in either ear. A pure-tone average showed 82.5 dBHL (air), 44.3 dBHL (bone) in the right ear and 93.8 dBHL (air), 48.8 dBHL (bone) in the left ear. Case 2 was a 38-year-old woman with a conventional hearing aid in her left ear, from which there was persistent aural discharge. A pure-tone average showed 48.8 dBHL(air), 15.0 dBHL (bone) in the right ear, and 60.0 dBHL(air), 20.0 dBHL(bone) in the left ear. Both underwent BAHA implant in the right ear without adverse reaction during 9 months of postoperative follow-up after surgery. No difference was seen in the aided hearing level or speech discrimination score between BAHA and air conduction hearing aids but both patients preferred to BAHA because of its greater comfort and audibility.
