骨导多频听觉稳态诱发反应的测试

Multiple auditory steady-state responses to bone conduction stimuli

目的:了解多频听觉稳态诱发反应(MASSR)对骨导客观听阈及对传导性聋评估的准确性。方法:对30例传导性聋患者进行气、骨导MASSR及纯音测听,并将MASSR反应阈和纯音听阈进行比较。结果:气、骨导MASSR反应阈和纯音听阈之间具有较好的相关性,MASSR对传导性聋评估的准确性和纯音测听相似。结论:MASSR可用作传导性聋患者客观听阈的评估。

Objective ： To assess the accuracy of threshold using the multiple auditory steady state responses （MASSR） to bone conduction stimuli in a group of patients with conductive hearing loss. Method： Thirty patients with conductive hearing loss were assessed by MASSR and by pure-tone audiometry, and compared the results of these two methods. Result：The thresholds of MASSR and those of PTA were significantly correlated, and the accuracy of MASSR were similar to PTA for the patients with conductive hearing loss. Conclusion： MASSR can be used to assess the hearing thresholds of patients with conductive hearing loss.
