Introduction: Deafness is defined as hearing impairments that can occur at any age and can be of genetic or idiopathic origin. They can occur both abruptly and gradually. The aim of this work is to underline the diagnostic and above all etiological contribution of spiral CT and MRI during deafness, which makes it possible to orient the therapeutic conduct. Materials and methods: We conducted a prospective work on patients explored in the radiology department of August 20 Hospital in Casablanca for deafness apart from chronic otitis media and post-traumatic deafness, between March 2012 and December 2013. 43 patients were explored by computed tomography (CT) of the rocks with multiplanar reconstructions (16 strips) and 37 patients were explored by magnetic resonance imaging (MRI) 1.5 Tesla. Results: There were 80 patients with an average age of 42 years. There was a female predominance (55 women for 25 men). Hearing loss was bilateral (75%), usually symmetrical 3 times greater than unilateral involvement (25%). This deafness was sudden in 30 patients (37.5%) and progressive installation in 50 patients (62.5%). Conductive hearing loss was found in 22 cases (27.5%), sensorineural hea
