Do I have case for the surgery of the choclear device

Hello Stephen, Based upon the information which you have offered, there may be multiple responsible parties potentially involved; however, a great deal more information is required to make any type of determination concerning viability.  The answer to your question can only be obtained through medical expert review of your medical records to determine if and by whom the standard of care was breached and if that breach directly caused your injuries. A Personal Injury Attorney can assist you in exploring these issues by interviewing you in depth and reviewing your medical records prior to sending them out for review by the appropriate medical experts. Consequently, if you are interested in consulting with one of us, you will have to reach out, as attorneys are unable to directly solicit on this forum. Do not delay, as the Statute of Limitation for bringing a Medical Malpractice lawsuit  is relatively short given the complexity involved in such cases.
