Model Number 304-20
Event Date 12/03/2012
Event Type  Injury  
Event Description

On (b)(6) 2012 clinic notes were received from a vns treating physician. Review of the clinic notes dated (b)(6) 2012 indicated that the patient has been having hoarseness and difficulty swallowing since the recent full revision surgery. The patient has clear dysphonia and increased weakness of the left arm. The physician reprogrammed the device at 0. 25ma and 0ma which did not change anything. The physician stated that he thinks this is just a postsurgical disturbance of the vagal nerve. They decided to turn the vns for two weeks and then have the vns turned back on in the hope that there will be some healing going on. The physician reported that the patient has damage to her vagal nerve and is experiencing vocal cord paralysis. Previously it had been reported that the patient was experiencing an increased coughing with stimulation after recent full revision surgery on (b)(6) 2012. Additional information was requested from the physician but the only further information he would provide was that he has still not seen the patient since the (b)(6) 2012 visit and that he did not believe she had seen an ear, nose, and throat (ent) physician.
