The bone-anchored hearing aid (BAHA) system can offer significant benefits to patients with single-sided deafness (SSD), primarily by lifting the head shadow effect.
To evaluate the efficacy of BAHA for SSD by comparing pre- and postoperative speech, spatial and qualities of hearing scale (SSQ) scores.
This was a prospective study conducted within a tertiary auditory implant department. The inclusion criteria were unilateral profound hearing loss with normal or mild high frequency hearing loss in the hearing ear (pure tone average better than or equal to 25 dBHL measured at 0.5, 1, 2 and 3 kHz) and subjective benefits reported by patients following a home trial with a BAHA Softband. Patients who met the above criteria and opted for surgery were asked to complete the SSQ questionnaire. The postoperative SSQ response was collected after at least 6 months of consistent BAHA usage.
This study included 25 adult patients (mean age at implantation 57.5 years). There was a statistically significant improvement in the average SSQ score in all three sections of the questionnaire with the use of the BAHA. Our patients experienced most marked benefits in speech hearing in challenging listening situations. All patients remain consistent users and there has been no explantation to date.
骨锚式助听器（BAHA）系统能为单侧耳聋（SSD）患者带来显著益处，主要是通过消除头影效应。
通过比较术前和术后言语、空间及听力质量量表（SSQ）评分，评估BAHA对SSD的疗效。
这是一项在三级听觉植入科室进行的前瞻性研究。纳入标准为患侧耳为单侧极重度听力损失且健侧耳高频听力正常或轻度损失（在0.5、1、2和3千赫兹处测量的纯音平均听阈优于或等于25分贝听力级），以及患者在家试用BAHA软带后报告有主观受益。符合上述标准并选择手术的患者被要求完成SSQ问卷。在持续使用BAHA至少6个月后收集术后SSQ回复。
本研究纳入了25名成年患者（植入时平均年龄57.5岁）。使用BAHA后，问卷所有三个部分的平均SSQ评分均有统计学意义上的显著改善。我们的患者在具有挑战性的聆听环境中的言语听力方面获益最为显著。所有患者均持续使用，迄今为止无移除装置的情况。
