What happens when the recurrent laryngeal nerve is damaged?
Injury to the recurrent laryngeal nerve has the potential to cause unilateral vocal cord paralysis. Patients with this typically complain of new-onset hoarseness, changes in vocal pitch, or noisy breathing.
What is Ligamentum Berry?
The Ligament of Berry is a dense condensation of pre-tracheal vascular fascia that attaches the thyroid to the crico-tracheal structures posteriorly. It was first described by Berry in 1888 who coined the suspensory ligament of the thyroid gland [21].
What is tracheoesophageal groove?
Tracheoesophageal groove is. the sulcus formed because of the abutment of the trachea. anteriorly and esophagus posteriorly and is useful for. identifying the RLN.
Which of the following is the most common type of injury on the recurrent laryngeal nerve after thyroidectomy?
The external branch of the SLN is probably the nerve most commonly injured in thyroid surgery. The rate of injury to the external branch of the SLN is estimated at 0-25%. This rate is probably underestimated, because the diagnosis is frequently missed.
Why are recurrent laryngeal nerves recurrent?
The recurrent laryngeal nerves branch from the vagus nerve, relative to which they get their names; the term “recurrent” from Latin: re- (back) and currere (to run), indicates they run in the opposite direction to the vagus nerves from which they branch.

What is the organ of zuckerkandl?
The organ of Zuckerkandl is a chromaffin body derived from neural crest located at the bifurcation of the aorta or at the origin of the inferior mesenteric artery. It can be the source of a paraganglioma.
What is tracheoesophageal fistula?
Esophageal atresia/tracheoesophageal fistula (EA/TEF) is a condition resulting from abnormal development before birth of the tube that carries food from the mouth to the stomach (the esophagus ).
What nerve is in the tracheoesophageal groove?
left recurrent laryngeal nerve
The left recurrent laryngeal nerve comes from the left vagus nerve, loops posteriorly around the arch of the aorta, and ascends in the tracheoesophageal groove posterior to the left lobe of the thyroid, where it enters the larynx and innervates the musculature in a similar fashion as the right nerve.
