[Management of the acoustic tumor in an only/better hearing ear].

Because profound bilateral hearing impairment is a catastrophic event, the management and care of an individual with an 8th nerve lesion in an only/better hearing ear remains a significant challenge for both patient and physician. Current options regarding the treatment of the acoustic tumor in an only/better hearing ear include: observation, attempted hearing preservation surgery and stereotactically guided radiation therapy. In this article, we present 3 cases of acoustic tumor within the internal auditory canal in an only/better hearing ear diagnosed by gadolinium-enhanced MRI and discuss the recommendations, especially observation, available in the care of these cases. In one patient, hearing disturbance caused by the tumor in a better hearing ear made the patient quite depressive and desperate. One of the most important consideration is for the physician to provide the patient with adequate informed consent regarding the possibility of profound bilateral hearing loss caused by either the natural growth or surgical removal of the tumor in the future, and alternative methods of communication with others such as: hearing aid and lip reading, cochlear implant and brainstem implant.
