Which nerve is closely related to the superior thyroid artery?
ব্যাখ্যা
The recurrent laryngeal nerve is closely related to the inferior thyroid artery and any damage to it during surgery may result in hoarse ness of the voice.
Injury to the external laryngeal nerve is more common because of its proximity to the superior thyroid artery. This leads to loss of tension in the vocal cord with diminished power and range in the voice. Patients, particularly those who use their voice professionally, must be advised that any thyroid operation will result in change to the voice even in the absence of nerve trauma.
