ABSTRACT
OBJECTIVE: To present the first reported case of intraneural direct cochlear nerve stimulation in a human being. STUDY DESIGN: This is a case report. RESULTS: A 23-year-old patient with bilateral progressive hearing loss associated with bilateral complete semicircular canal aplasia and ossified cochleas underwent cochlear implantation. During surgery, a patent cochlear lumen could not be found, and the array was positioned in the internal auditory canal adjacent to the cochlear nerve. Against our expectations, an assiduous rehabilitation and frequent fitting adjustments have led to a word recognition score, in open set speech with lip reading, of 18/25 and acceptable frequency discrimination. CONCLUSIONS: We are aware that this was an anomalous use of the cochlear implant, and it is not our aim to suggest a new indication for cochlear array positioning. However, this case shows that auditory perception, to some degree, can be obtained with intraneural direct cochlear nerve stimulation.

A high incidence of oropharyngeal dysphagia (OD) in acute-care settings has been reported; however, no data on its management are found in the literature. Here we report the experience with rehabilitative management of OD in a large Italian hospital. The characteristics of inpatients with OD during 2004 have been studied prospectively. For each patient, demographic data, the department referring the patient, the disease causing OD, and the presence of a communication disorder were registered. The swallowing level at the beginning and at the end of rehabilitation were recorded. Of the 35,590 inpatients admitted to San Giovanni Battista Hospital of Turin during 2004, 222 of them were referred for the assessment and rehabilitation of OD. The inpatients with OD came from different departments and mainly had a neurologic disease. In 110 patients a communication disorder was present. The swallowing impairment was moderate to severe at the moment of referral, while on average patients were able to eat by mouth after swallowing therapy. Dysphagia rehabilitation in an acute care setting is requested from different departments because of its prevalence and severity; skilled specialists are needed for early assessment and the best management.
