Laryngeal electromyography (LEMG) is a diagnostic procedure that is used to determine how strong the laryngeal nerves are. It is a nearly painless procedure that is done on an outpatient basis in conjunction with a neurologist.
The purpose of LEMG is to find out how strong the vocal nerves are. It is most commonly performed after a known vocal injury, such as vocal weakness after surgery (i.e., thyroid surgery, spine surgery, etc). It allows the physician to determine how strong the nerve is and may predict the likelihood of recovery.
This information can be critical in developing a treatment plan and ensuring the patient undergoes the correct procedure.
Very few physicians are able to perform LEMG as it requires specialized skills in needle placement as well as interpretation of results.
