BACKGROUND: With the development of inner ear gadolinium imaging technology, its clinical application is more and more frequent.
OBJECTIVES: To explore the application value of inner ear MRI after intravenous gadolinium injection in sudden sensorineural hearing loss.
MATERIAL AND METHODS: The clinical data of 28 patients who were preliminarily diagnosed with sudden sensorineural hearing loss and the results of intravenous gadolinium MRI examination were analyzed to find the relationship between them.
RESULTS: Of the 28 patients (30 ears) with idiopathic sudden sensorineural hearing loss, 20 (71.4%) showed normal MRI. MRI abnormalities related to hearing loss were found in 8 cases (28.6%), of which 5 cases (17.9%) showed hydrops in the inner ear membrane labyrinth, 2 cases (7.1%) showed mastoiditis on the affected side, and 1 case (3.6%) showed vestibular schwannoma.
CONCLUSIONS AND SIGNIFICANCE: Inner ear MRI after intravenous gadolinium injection can be used as an index to detect the cause of sudden deafness, one of the factors to guide clinical treatment, and an important means to further explore the relationship between hydrops of membranous labyrinth and SSNHL.
