: Is there any data available on the risks or incidence of damage to the
vagus/recurrent
laryngealCancer - throat or larynx
Laryngeal nerve damage nerveNerve biopsy
Nerve conduction velocity resulting from cutting the chest in bypass surgery?
Thanks for any help you may provide.
======================================================================
Recurrent laryngeal nerve damage is quite rare and seldom mentioned but
has been described in 1.9% of a survey of 270 patients undergoing
bypass in one survey. It can be caused by hypothermic
damage from ice used to cool the heart in some procedures, cannulation
of vessels in the neck and damage from the cuff of the Endotracheal tube.
Recurrent laryngeal nerve damage causes speech problems ,
swallowing problems are caused by damage to the vagus nerve.
I could find no reference to vagus nerve damage during bypass surgery in
a 20 year literature search.
