This study demonstrates that electric-acoustic stimulation (EAS) significantly decreases the subjective impairment in speech perception.
To assess the subjective benefit of EAS over the first 12 months after EAS fitting using the Abbreviated Profile of Hearing Aid Benefit (APHAB).
Twenty-three EAS users, implanted with either the PULSAR(CI)(100) FLEX(EAS) provided with the DUET EAS processor or the COMBI40+ Medium provided with the TEMPO+ speech processor, were included. Electric stimulation was activated about 1 month postoperatively; ipsilateral acoustic stimulation was added 2 months thereafter. EAS benefit was measured preoperatively with only a hearing aid and postoperatively at EAS fitting and then 3, 6 and 12 months after EAS fitting using the APHAB.
Subjects reported significant improvements in the global score with a mean decrease in impairment from 74% preoperatively to 45% after 3 months of EAS use. Furthermore, clinical relevance was demonstrated in multiple subscales between preoperative and first fitting reflecting a true benefit of EAS with a probability of 95%.
本研究表明，电声刺激（EAS）能显著降低言语感知方面的主观障碍。
使用助听器受益简表（APHAB）评估电声刺激（EAS）装置佩戴后头12个月内的主观获益情况。
纳入23名EAS使用者，他们植入的装置要么是配备DUET EAS处理器的PULSAR(CI)(100) FLEX(EAS)，要么是配备TEMPO+言语处理器的COMBI40+ Medium。术后约1个月开启电刺激；此后2个月添加同侧声刺激。术前仅使用助听器测量EAS获益情况，术后在EAS装置佩戴时测量，然后在EAS装置佩戴后3个月、6个月和12个月使用APHAB进行测量。
受试者报告整体得分有显著改善，使用EAS 3个月后，损伤平均从术前的74%降至45%。此外，术前与首次装置佩戴之间多个分量表显示出临床相关性，这反映了EAS具有真实的益处，概率为95%。
