Introduction: The radiological diagnosis has a very important part in the evaluation of several otorhinolaryngological problems. Magnetic resonance imaging (MRI) is the gold standard examination technique for otorhinolaryngological problems because of its advantages such as the detection of abnormalities in soft tissues such as cochlear obliteration, cochlear nerve aplasia, and large endolymphatic saccule and retrocochlear lesions.

Objective: To analyze the MRI of patients with hearing loss of an audiology ambulatory in Bahia.

Materials and Methods: A prospective study that evaluated the MRI of 145 patients with sensorineural hearing loss in the audiology ambulatory of Otorrinos Hospital in Feira de Santana, Bahia, between 2012 and 2013.

Results: Of all the patients, MRI was not performed on 62.6%. From 54 patients on whom it was performed, 76% showed no alterations, 5.4% were with schwannomas, 1.9% had cochlear nerve atrophy, and large vestibular aqueduct, meningioma, and vert-basilar system alterations.

Conclusion: RMI is an essential tool for the diagnosis of otorhinolaryngological pathologies.
