The importance of pyramidal lobe in thyroid surgery.

Abstract

The intraoperative frequence of PL is 12%, and it is considered a normal component of the thyroid. Scintigraphic visualization of the PL depends on the kind of thyroid disorder and on the experience of radiologist, so the PL can often not be diagnosed by scintigraphic imaging. Finally, the whole anterior cervical region has to be investigated very carefully during thyropidectomy not to overlook a long or thin pyramidal lobe or other ectopic thyroid tissue because actually doesn't exist the goldstandard preoperative method to diagnoses PL.
