The Ear in Head Trauma  After skull trauma, according to Piquet and Decroix,217 it is possible to find many varying clinical characteristics of deafness —in short, the most frequent nature of hearing loss is a perception deafness, but we also see the mixed type. Pure transmission or total hearing loss are exceptional. Frequently the hearing recovers during the first or second month after the trauma, but in some cases the defect persists. We can consider it as permanent when it is present for six months. The hearing tests often show that recruitment is at first negative, then positive. The authors think that it is the result of vascular phenomena which appear in the circulation of the inner ear and of the cochlear nerve and which are due to the fragility provoked by the trauma.From anamnestical data of 1,188 cases with craniocerebral injuries, damage to the cochlear nerve was established
