Transitions in auditory rehabilitation with bone conduction implants (BCI)

Abstract

Background: The bone conductive implants (BCI) are nowadays a reliable alternative for rehabilitation of specific forms of hearing loss, i.e. conductive, mixed or single sided deafness (SSD).

Aims/Objective: To analyse the various factors in play when considering an auditory rehabilitation with a bone-conductive device (BCI).

Materials and Methods: The clinical charts of subjects who underwent BCI application at the same Implanting Center from 2005 to 2018 were retrieved analysing also the reason for eventual explantation and the alternative option (transition) for hearing rehabilitation.

Results: Nine BAHA Compact, 4 BAHA Intenso, 21 BAHA Divino, 3 BAHA BP100, 4 Ponto, 2 Sophono, 5 Bonebridge, 5 BAHA5 Attract; 11 BAHA5 Connect were used in 12 unilateral COM; 16 bilateral COM; 3 unilateral cholesteatoma; 6 bilateral cholesteatoma; 2 unilateral otosclerosis; 5 bilateral otosclerosis; 9 congenital malformations; 6 major otoneurosurgical procedures; 5 sudden deafness. Explantation was necessary for five subjects.

Conclusions: Middle ear pathology and sequels from surgery represent the most common reason for BCI implantation, both in unilateral and in bilateral cases. Transition from one implantable device to another one can be predictable, mostly when explantation is necessary.

Significance: The role of BCI for rehabilitation in middle ear pathology may be extremely important.

背景：如今, 骨传导植入体（BCI）是康复某些特定形式的听力损失（即传导性的、混合的或单侧耳聋（SSD））的可靠的替代方案。

目的：分析各种考虑使用骨传导植入体（BCI）进行听觉康复的影响因素。

材料和方法：检索2005年至2018年在同一植入中心接受BCI的受试者的临床图表, 分析最终移出的原因和听力康复的替代选择（过渡）。

结果：9个BAHA Compact, 4个BAHA Intenso, 21个BAHA Divino, 3个BAHA BP100, 4个Ponto, 2个Sophono, 5个Bonebridge, 5个BAHA5 Attract; 11个BAHA5 Connect用于12个单侧COM; 16个双侧COM; 3例单侧胆脂瘤; 6例双侧胆脂瘤; 2例单侧耳硬化症; 5例双侧耳硬化症; 9例先天性畸形; 6项大的耳鼻喉科手术; 5例突然耳聋。五名受试者需要进行移植手术。

结论：中耳病理和手术后遗症是BCI植入最常见的原因, 无论是单侧还是双侧。从一个植入体转用另一个植入体是可预测的, 主要是当移出是必须的时候。

意义：BCI在中耳病理康复中的作用可能非常重要。
