MRI evidence of inner ear hemorrhage in prognostic assessment of sudden sensorineural hearing loss

Abstract

Objectives

This study sought to explore the association between MRI-detected inner ear hemorrhage and the prognosis and symptom of SSNHL.

Methods

A total of220 enrolled patients were asked to receive MRI and hearing test.

Results

Patients with MRI evidence of inner ear hemorrhage experienced significantly more severe hearing loss, differences in hearing before and after treatment, and subjective perceptions compared to individuals without these signs. The hearing recovery at speech frequencies (0.5, 1, 2 kHz) was better in the non-hemorrhage group compared to the hemorrhage group. Additionally, the non-hemorrhage group exhibited fewer symptoms of dizziness and a better prognosis for dizziness.

Conclusion

MRI played a crucial role in both identifying the location of hemorrhage and accurately predicting symptoms and prognosis.
