On (b)(6), 2013, the patient's father reported that the patient has been experiencing several adverse events after having his most recent vns replacement on (b)(6), 2013. The adverse events included losing his voice, coughing and choking while he eats, aspiration pneumonia, and a hole in an unspecified location. Attempts for additional information have been made; however, they were unsuccessful. No additional information has been provided.

Event Description

The patient was seen for follow-up with the surgeon. The device interrogation was within normal limits. The surgeon indicated that he initially thought the patient's issues were due to the patient being intubated for implant surgery. The surgeon indicated that the patient likely has recurrent left laryngeal polyps which he feels will continue to heal over the next six months. The surgeon offered the patient a follow-up appointment in three months. The surgeon reported that it is reasonable that scar tissue could have been dissected and such outcomes would be reasonable to occur.
