Abstract
|
|
|
A non-recurrent laryngeal nerve is rarely encountered condition, and its anomalous path makes it more vulnerable to injury during thyroid surgery and compression by a thyroid mass. This anomaly appears as a consequence of an aberrant subclavian
artery,
which arises from an anomaly in the primitive forth aortic arch. So, the surgeon must always be aware of the possibility of a nonrecurrent laryngeal nerve. Pre-operative recognition of this nerve allows surgeons to avoid the nerve injury. In some
cases,
surgeons are able to predict the presence of this nerve pre-operatively by way of clinical symptoms, chest X-ray or barium swallow. We experienced a case of right nonrecurrent laryngeal nerve during a total thyroidectomy in a 47-year-old female,
and
report with literature review.
