Also , you may want to ask whether the doctor you are choosing is using the nerve monitoring device - it is a special tube , either Endotracheal tube-based EMG monitoring, used for prevention of injuring laryngeal nerves which are very small in diameter, and
in consequence relatively easy to injure by traction , or Dedicated EMG
endotracheal tube(used by Anesthesiologist)
It is a standards of care to use it , but not all surgeons are comfortable with it and not all use it.
