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 understand the objective hearing threshold of multi-frequency auditory steady-state response (MASSR) and the assessment of conduction hearing loss. Methods: Thirty patients with conduction deafness underwent gas and bone conduction MASSR and pure tone audiometry. The MASSR threshold and pure tone threshold were compared. Results: There was a good correlation between gas and bone conduction MASSR threshold and pure tone threshold. The accuracy of MASSR in assessment of conductive hearing loss was similar to pure tone audiometry. Conclusion: MASSR can be used as an assessment of objective hearing threshold in patients with conductive deafness.
