ABSTRACT
Ortner’s syndrome, also
known as the syndrome cardiovocal, is characterized by the compression,
stretching or dissection of recurrent laryngeal nerve, secondarily caused by
cardiovascular abnormal. Through a systematic review about the issue, on the
main bases data, we named the main aspects which go around the syndrome, from
its symptoms to its treatments based on its different causes, such as, valvar
mitral stenosis, aortic aneurysm among others whose effect brings about a
compression of the recurrent laryngeal nerve. Therefore, the left recurrent
laryngeal nerve is more affected because of its anatomical position. Due to its
path surrounding aortic arch and passing between pulmonary artery and aortic
arch, it has a greater chance to compression. Its clinical importance is
related to differential diagnosis which is also connected to many different
pathologies such as neoplasia (pulmonary, thyroid, mediastinal, esophageal) and
surgical iatrogenic causes which may affect the recurrent laryngeal nerve
causing various symptoms related to this involvement.
